New Federal Data Shows Decrease in Drunk Driving Rates

Image result for decrease in dui

According to reporter Christopher Ingraham of the Washington Post, new federal statistics show that the rate of drunken driving in the United States fell to a 13-year low in 2014, the latest year for which data is available. The rate of driving under the influence of illicit drugs has not changed meaningfully in recent years but remains slightly lower than it was in 2008 and 2009 at the start of the Obama administration.

Here’s a summary of some other findings:

  • In 2014, 27.7 million people aged 16 or older (11.1 percent) drove under the influence of alcohol in the past year, and 10.1 million (4.1 percent) drove under the influence of illicit drugs in the past year. About 7.0 million (2.8 percent) drove under the influence of alcohol and illicit drugs in the past year, including 5.9 million (2.4 percent) who drove under the simultaneous influence of alcohol and illicit drugs in the past year.
  • The percentage of people driving under the influence generally increased with age through the young adult years and then declined with age thereafter; percentages were higher among males than females.
  • The percentage of people aged 16 or older who drove under the influence of alcohol in 2014 (11.1 percent) was lower than the percentages in 2002 through 2012 (ranging from 11.8 to 15.3 percent).
  • The percentage of people aged 16 or older who drove under the influence of illicit drugs was lower in 2014 (4.1 percent) than in 2002 through 2006 and in 2009 through 2010.
  • The percentage of people aged 16 or older who drove under the simultaneous influence of alcohol and illicit drugs was lower in 2014 (2.4 percent) than in 2002 through 2010 (ranging from 2.9 to 3.4 percent).

Ingraham reported that although experts caution that while the trend is heading in the right direction, there’s still a lot of work to be done. “Although it is heartening to see a downward trend in levels of driving under the influence of alcohol, it still kills thousands of people each year and shatters the lives of friends and loved ones left behind,” said Frances Harding, director of the Center for Substance Abuse Prevention at SAMHSA, the agency that produces the survey.

The SAMHSA survey showed that young adults — particularly men ages 21 to 25 — had by far the highest impaired driving rates. More than 1 in 5 men ages 21 to 25 drove drunk in 2014, nearly 1 in 7 drove under the influence of other drugs, and roughly 1 in 12 drove while simultaneously drunk and drugged.

One the other hand, young adults have also seen the greatest reductions in drunken driving prevalence over the past 13 years. Since 2002, the drunken driving rate fell by fewer than three percentage points among drivers age 26 and older. But the rate among drivers ages 21 to 25 dropped by more than 10 percentage points. And the prevalence among the youngest drivers, ages 16 to 20, fell by more than half.

Ingraham reports there’s no single factor driving the decline in drunken driving rates. The Centers for Disease Control and Prevention credits interventions like strong drunken driving laws, public awareness campaigns, and ignition interlock systems that don’t allow drunk drivers to start cars.

Some states are experimenting with innovative programs that essentially take away the right to drink alcohol, period, for people convicted of certain alcohol-related crimes. There’s also evidence that ride-sharing services like Uber can reduce drunken driving rates, although not all researchers agree on this.

My opinion? This is extremely good news. Although it’s important to save lives by reducing traffic accidents through education, prevention, and all other possible measures; it’s equally important that defendants facing these criminal charges hire capable and competent defense counsel as soon as possible to protect their rights, review the evidence and ensure a fair trial when necessary.

What Happened After Voters Legalized Recreational Marijuana?

Reporter Christopher Ingraham of the Washington Post wrote an article discussing how that the availability of recreational marijuana — in Colorado and elsewhere — is having little to no effect on teens’ propensity to smoke weed.

COLORADO

In his article, Ingraham supports his claim with the official statistics out of Colorado through 2015. It’s also what federal data shows nationwide through this year. And it’s also backed up by other federal surveys of drug use in the states where marijuana is legal.

It appears the data on this point has been consistent enough that longtime skeptics of the merits of marijuana legalization, like Nora Volkow of the National Institute on Drug Abuse, are expressing surprise at the findings. “We had predicted based on the changes in legalization, culture in the U.S. as well as decreasing perceptions among teenagers that marijuana was harmful that [accessibility and use] would go up,” Volkow told U.S. News and World Report earlier this month. “But it hasn’t gone up.”

WASHINGTON

However, a study out Tuesday in the journal JAMA Pediatrics flies somewhat in the face of the new conventional marijuana wisdom. Examining marijuana use among high school students in Washington state two years before and after the vote to legalize in 2012, it finds that rates of marijuana use increased by about 3 percent among 8th- and 10th-graders over that period.

INTERPRETING THE FINDINGS

The authors posit that reduced stigma about marijuana use is one factor leading to the results that they observed.

“Our study suggests that legalization of marijuana in Washington reduced stigma and perceived risk of use,” said lead author Magdalena Cerdá of the University of California in Davis in a news release, “which could explain why younger adolescents are using more marijuana after legalization.”

The findings are something of a puzzle. The study found no change in marijuana use among 12th-graders in Washington state, which the authors said could be because the 12th-graders in the study were old enough that “they had already formed attitudes and beliefs related to marijuana use” before the legal change.

The study also found no change in use among students at any grade level in Colorado. The authors write that Colorado had a robust medical marijuana industry in place well before full legalization, which may have affected youth attitudes and behaviors there before the study period.

Among adolescents, the perceived harmfulness of marijuana has been declining for decades among all age groups. But at the same time, adolescent use of marijuana has been flat or falling. This has led some researchers, including Mark Kleiman of New York University, to rethink the nature of the link between what teens think about weed and whether they use it.

In an email, Kleiman pointed out that in Washington state, the recreational marijuana market didn’t open until halfway through 2014, and then only in limited form. That’s halfway through the “after” period (2013 to 2015) in the JAMA Pediatrics study.

“The effect of the legalization initiatives themselves on price and availability of cannabis really wasn’t felt until after” the study’s surveys were done, Kleiman said. “Any measured effect would be more likely the result of the political campaign around legalization than legalization itself.”

Indeed, the study’s authors agree with that assessment. “Simply legalizing an activity can change people’s views about it and can change their behaviors as well,” said co-author Deborah Hasin of Columbia University in an email.

Exonerations On the Rise

 

Image result for exoneration

News reporters Alanna Durkin Richer  and Curt Anderson of the Associated Press wrote an article describing how last year, 68 out of 157 exonerations were cases in which the defendant pleaded guilty. In Trial or Deal? Some Driven to Plead Guilty, Later Exonerated the article describes the difficult dilemma of many defendants in the criminal justice system: either accept the Prosecutor’s plea offer or risk facing much harsher consequences if found guilty at trial.

Apparently, more than 300 of the more than 1,900 people who have been exonerated in the U.S. since 1989 pleaded guilty, according to an estimate by the National Registry of Exonerations. The registry is maintained by the University of Michigan Law School using public information, such as court documents and news articles.

Last year, 68 out of 157 exonerations were cases in which the defendant pleaded guilty, more than any previous year. The numbers reflect an overwhelmed criminal justice system with public defenders taking more cases than they can handle; as well as court officials who try saving the government money with plea bargains compared with costly trials.

The data is even more daunting. Last year, more than 97 percent of criminal defendants sentenced in federal court pleaded guilty compared with about 85 percent more than 30 years ago, according to data collected by the Administrative Office of the U.S. Courts. The increase in guilty pleas has been a gradual rise over the last three decades.

No one knows exactly how many innocent people are behind bars for pleading guilty. Sociologists have estimated that between 2 and 8 percent of people who plead guilty are in fact innocent.

The article emphasized how defendants who were exonerated after pleading guilty often have prior criminal records and come from poor backgrounds and are not well-educated. They’re typically represented by public defenders juggling dozens of cases in a day.

Many exonerees were cleared of wrongdoing by taking a new look at DNA evidence in blood or other body fluids, according to the University of Michigan database. Some were the victims of prosecutorial misconduct, while shoddy police work was to blame in other cases — such as a mistaken FBI hair analysis or falsified fingerprint evidence. Some falsely confessed because of improper interrogation techniques while others maintained their innocence throughout.

Making the matter worse, it’s not just prosecutors and defense attorneys who seek to cut plea deals. The article said many judges prefer that route, too. Judges who resolve cases rather than let them languish tend to be seen as more successful. Similarly, explained the article, prosecutors who close cases tend to rise faster in their careers.

My opinion? People facing criminal charges MUST seek experienced defense counsel to defend their rights, investigate the facts, interview witnesses, argue pretrial motions, put their clients in the best light possible and conduct an active; fair trial when necessary.

Pleas contact my office as soon as possible if you, a friend or family member is facing criminal charges. The epidemic of increased exonerations due to injustice in our courts as well as our incoming administration’s trampling of individual rights shows a growing need for competent representation. Put simply, defendants should not plead guilty to criminal charges they are not guilty of.

Felony Disenfranchisement & Voting.

Image result for disenfranchised felon

A new study conducted by professors Christopher Uggen, Ryan Larson, and Sarah Shannon and released by the Sentencing Project reveals that a record 6.1 million Americans are forbidden to vote because of felony disenfranchisement, or laws restricting voting rights for those convicted of felony-level crimes. The number of disenfranchised individuals has increased dramatically along with the rise in criminal justice populations in recent decades, rising from an estimated 1.17 million in 1976 to 6.1 million today.

Apparently, the United States remains one of the world’s strictest nations when it comes to denying the right to vote to citizens convicted of crimes. An estimated 6.1 million Americans are forbidden to vote because of “felony disenfranchisement,” or laws restricting voting rights for those convicted of felony-level crimes.

The study’s key findings include the following:

  • As of 2016, an estimated 6.1 million people are disenfranchised due to a felony conviction, a figure that has escalated dramatically in recent decades as the population under criminal justice supervision has increased. There were an estimated 1.17 million people disenfranchised in 1976, 3.34 million in 1996, and 5.85 million in 2010.
  • Approximately 2.5 percent of the total U.S. voting age population – 1 of every 40 adults – is disenfranchised due to a current or previous felony conviction.
  • Individuals who have completed their sentences in the twelve states that disenfranchise people post-sentence make up over 50 percent of the entire disenfranchised population, totaling almost 3.1 million people.
  • Rates of disenfranchisement vary dramatically by state due to broad variations in voting prohibitions. In six states – Alabama, Florida, Kentucky, Mississippi, Tennessee, and Virginia – more than 7 percent of the adult population is disenfranchised.
  • The state of Florida alone accounts for more than a quarter (27 percent) of the disenfranchised population nationally, and its nearly 1.5 million individuals disenfranchised post-sentence account for nearly half (48 percent) of the national total.
  • One in 13 African Americans of voting age is disenfranchised, a rate more than four times greater than that of non-African Americans. Over 7.4 percent of the adult African American population is disenfranchised compared to 1.8 percent of the non-African American population.
  • African American disenfranchisement rates also vary significantly by state. In four states – Florida (21 percent), Kentucky (26 percent), Tennessee (21 percent), and Virginia (22 percent) – more than one in five African Americans is disenfranchised.

My opinion? It makes no sense why convicts are prevented from voting if they’ve been sentenced and punished. It’s a terrible violation of civil rights. Period. Please contact my office if you’re a convicted felon who has paid your debt to society and want your voting rights and/or firearms rights restored.

Marijuana Arrests Increase.

Image result for mass incarceration blacks for drug crimes

Excellent article from reporter Timothy Williams of the New York Times discusses a new study by the American Civil Liberties Union and Human Rights Watch which reveals that marijuana arrests were about 13.6 percent more than the 505,681 arrests made for all violent crimes, including murder, rape and serious assaults.

The report comes in the wake of the fatal police shooting of Keith Lamont Scott last month in Charlotte, N.C. Mr. Scott, 43, had attracted police attention in part because, the police said, he was smoking marijuana.

The report is the latest study to highlight the disparate treatment African-Americans often receive in the criminal justice system, including disproportionate numbers of blacks who are sent to jail when they are unable to pay court-imposed fees, or stopped by the police during traffic stops or while riding bicycles. Its many findings are disturbing.

THE REPORT’S FINDINGS:

  • Although whites are more likely than blacks to use illicit drugs — including marijuana, cocaine, heroin, methamphetamine and prescription drugs for nonmedical purposes — black adults were more than two-and-a-half times as likely to be arrested.
  • In Iowa, Montana and Vermont — places with relatively small populations of African Americans — blacks were more than six times as likely to be arrested on drug possession charges than whites.
  • In terms of marijuana possession, black adults were more than four times as likely to be arrested as white adults in the 39 states in which sufficient data was available.
  • In Manhattan, where blacks make up about 15 percent of the population, African-Americans are nearly 11 times as likely as whites to be arrested on drug possession.
  • African-Americans may also be more apt to face arrest, according to researchers, because they might be more likely to smoke marijuana outdoors, attracting the attention of the police.
  • The above disparities persist whether there are few or many African-Americans in a given area.

Mr. Williams also wrote that, according to criminologists, African-Americans are arrested more often than whites and others for drug possession in large part because of questionable police practices. Police departments, for example, typically send large numbers of officers to neighborhoods that have high crime rates. A result is that any offense — including minor ones like loitering, jaywalking or smoking marijuana — can lead to an arrest, which in turn drives up arrest rate statistics, leading to even greater police vigilance.

“It is selective enforcement, and the example I like to use is that you have all sorts of drug use inside elite college dorms, but you don’t see the police busting through doors,” said Inimai M. Chettiar, director of the Justice Program at New York University’s Brennan Center for Justice.

“Voodoo Science” Debunked

Image result for voodoo science

Interesting article from the Wall Street Journal written Alex Kozinski , a judge on the Ninth Circuit Court of Appeals since 1985, discusses how the U.S. has relied on flawed forensic evidence techniques for decades, resulting in false convictions.

According to Judge Kozinski, the White House released a report that fundamentally changes the way many criminal trials are conducted. The new study from the President’s Council of Advisors on Science and Technology (PCAST) examines the scientific validity of forensic-evidence techniques—DNA, fingerprint, bitemark, firearm, footwear and hair analysis. It concludes that virtually all of these methods are flawed, some irredeemably so.

The study indicates that only the most basic form of DNA analysis is scientifically reliable. Some forensic methods have significant error rates and others are rank guesswork. “The prospects of developing bitemark analysis into a scientifically valid method” are low, according to the report. In plain terms, says Judge Kozinski, “Bitemark analysis is about as reliable as astrology.” Yet many unfortunate defendants languish in prison based on bad science.

Even more disturbing, the article states that forensic scientists – who are often members of the prosecution team – sometimes see their job as helping to get a conviction. This can lead them to fabricate evidence or commit perjury, says Judge Kozinski. Many forensic examiners are poorly trained and supervised. They sometimes overstate the strength of their conclusions by claiming that the risk of error is “vanishingly small,” “essentially zero,” or “microscopic.” The report calls such claims “scientifically indefensible,” but jurors generally take them as gospel when presented by government witnesses who are certified as scientific experts.

Apparently, problems with forensic evidence have plagued the criminal-justice system for years.

The PCAST report recommends developing standards for validating forensic methods, training forensic examiners and making forensic labs independent of police and prosecutors. “All should be swiftly implemented,” says Judge Kozinski, who adds that preventing the incarceration and execution of innocent persons is as good a use of tax dollars as any:

“Among the more than 2.2 million inmates in U.S. prisons and jails, countless may have been convicted using unreliable or fabricated forensic science. The U.S. has an abiding and unfulfilled moral obligation to free citizens who were imprisoned by such questionable means. If your son or daughter, sibling or cousin, best friend or spouse, was the victim of voodoo science, you would expect no less.”

My opinion? Jurors rely HEAVILY on forensic evidence in their deliberations. And it makes sense: it’s a huge task to weigh evidence and sift through the rhetoric of arguments from the prosecution and defense. Cold, hard, quantifiable and scientific facts make it easy for jurors to render decisions.

Consequently, the information from this report is both good and bad news. It’s good because the truth about  “voodoo science” in the courtroom has finally surfaced to the mainstream. It’s bad because hundreds, if not thousands of innocent people are convicted of crimes and serve years in prison based on unreliable evidence for crimes they didn’t commit.

Fortunately, there’s hope. According to Judge Kozinski, the report “provides a road map for defense lawyers to challenge prosecution experts.” Excellent.

Competent attorneys should immediately gain an understanding of challenging prosecution experts who bring voodoo science in the courtroom. It’s the only way to shed light on this grim subject and bring justice to our courts.

New Washington Driver’s-License Exam Tackles Pot & Cellphone Risks

A recent news article by reporter E.J. Smith III of the Seattle Times reports that today’s driver’s license exams require not only a more thorough understanding of longstanding traffic laws but also an understanding of the risks associated with smartphones and the legalization of pot.

“We wanted to add more information about impaired driving beyond the information about driving while intoxicated,” said Department of Licensing spokesman Brad Benfield. “With all the growth of cellphone use … we wanted to make sure that type of information was highlighted in the driver’s guide and test.”

E.J. Smith III reports these driving issues are timely and should be addressed. For example, he quotes a recent study by the AAA Foundation for Traffic Safety concluded that teen drivers spend nearly a quarter of their driving time distracted. Additionally, one in six drivers involved in fatal crashes in Washington in 2014 had recently used marijuana, which is the most recent data available. Finally, according to the NSC preliminary estimates, 567 people died in motor-vehicle crashes in Washington last year, a 21 percent increase over 2014. Nationally, the increase was 8 percent.

“The old test didn’t have any questions on distractions,” said Nur Hassan, who has run MLK Simple Driving School in Seattle for three years. “Driving is very serious business, so people should not try to take it lightly or try to put in other distractions.”

My opinion? Kudos to the Department of Licensing for addressing issues of distracted driving and marijuana use. This is an excellent step in the right direction. Today’s teen driver’s need to know the risks of their driving behavior.

I practice a wide range of criminal defense, everything from low-level misdemeanors to Federal charges. I’m honored to represent them through difficult times. I’ve assisted clients who are minors charged with various forms of DUI (drugs as well as alcohol). Many didn’t know the slightest amount of alcohol or drugs in their system can lead to DUI charges. Others didn’t know the repercussions of their actions.

I’m a firm believer that education is the key to prevention. That said, if you’re interested in more information on these issues then please review my Drug DUI practice area and my Legal Guide titled Drug DUI’s in Washington: The Issues & Recent Case Law.

Is Cash Bail Effective?

Image result for cash bail

Three research studies released this month further confirm the ineffective, discriminatory, and unsafe influence of money bail in U.S. criminal justice systems.

In The Heavy Costs of High Bail: Evidence from Judge Randomization, a Columbia Law and Economics Working Paper by Arpit Gupta, Christopher Hansman, and Ethan Frenchman, describes how assigning money bail to people accused of crime in Philadelphia and Pittsburgh increases the likelihood of conviction by 12% and increases recidivism by 4%. Ultimately, the authors found that the use of money bail is not effective – it “does not seem to increase the probability that a defendant appears at trial,” and actually makes us all less safe.

In her University of Pennsylvania Law School Working Paper, Distortion of Justice: How the Inability to Pay Bail Affects Case Outcomes, Megan Stevenson reports that people arrested for crimes in Philadelphia and detained due to their inability to pay money bail face up to a 30% increase in convictions—driven by increased guilty pleas—and an additional 18 months of incarceration compared to those who are able to afford bail.

Finally, the Prison Policy Initiative (PPI) released an analysis of national data that gives context to the Columbia and University of Pennsylvania papers. In Detaining the Poor: How money bail perpetuates an endless cycle of poverty and jail time, PPI found that “most of the people who are unable to meet bail fall into the poorest third of society.” Their median income – only $15,109 prior to incarceration – was less than half of the income of non-incarcerated people, and yet the median bail amount nationally is almost a full year’s income for the typical person unable to post a bail bond. Money bail, PPI concludes, results in the unnecessary and excessive detention of poor people, essentially jailing people for their poverty.

This research highlights what legislators, practitioners, and taxpayers are increasingly recognizing: money bail doesn’t work, is discriminatory, and makes communities less safe.

Cherise Fanno Burdeen, executive director of the Pretrial Justice Institute released this statement about the research:

“With these recent research findings, there should no longer be any doubt, anywhere, that money bail unfairly punishes the poor while also making everyone less safe. Our 3DaysCount campaign calls for replacing the broken money bail system with commonsense and proven solutions to support people being successful on pretrial release.”

Congressman Ted Lieu, sponsor of the No Money Bail Act of 2016, said the following:

“Our nation must stop criminalizing poverty, and these new studies provide crucial data proving that being poor increases your chance of jail time and conviction.  This kind of research is crucial to supporting the No Money Bail Act of 2016, which would eliminate the use of money bail at the federal level and incentivize states to end the use of bail through the withholding of federal grants. We can no longer stand by in good conscience while Americans, presumed innocent, are deprived of their liberty because they can’t afford bail. Justice in America should not be bought and paid for.”

Additionally, judicial leaders across the nation joined together to call attention to these findings.Chief Justice W. Scott Bales, Arizona Supreme Court; Chief Justice Patricia Breckenridge, Missouri Supreme Court; Chief Justice E. James Burke, Wyoming Supreme Court; Chief Justice Tani Cantil-Sakauye California Supreme Court;  Justice Charles W. Daniels, New Mexico Supreme Court; Chief Justice Matthew B. Durrant,Utah Supreme Court; Chief Judge Nan G. Nash, Second Judicial District, New Mexico;Chief Justice Mark E. Recktenwald, Supreme Court of Hawaii; and Chief Justice Robert J. Torres, Jr., Supreme Court of Guam issued the following statement:

“People should not be held in jail pending the disposition of charges merely because they are poor and cannot afford bail.  Recent research suggests that we can identify better ways to make release decisions that will treat people fairly, protect the public, and ensure court appearances.”

My opinion? This national effort is gratifying. Few people understand how incarceration negatively affects job opportunities, families and ability mental/emotional wellness. In my Legal Guide titled, “Making Bail,” I discuss how one of the greatest services a competent defense attorney can do for their clients is assist in getting them released from jail as soon as possible on either a reduced bail amount which is lower than the Prosecutor’s recommendations or that the defendant be released without bail altogether.

One opportunity to lower/rescind bail is at the defendant’s first appearance or arraignment. Another opportunity exists through a Bail Review Hearing.

Under CrR 3.2, judges must review the nature of the pending criminal charges, a defendant’s prior criminal history, their history of failing to appear at past court hearings, and their ties to the community (property ownership, employment, family, school, etc). Factoring all of this, the judge decides whether to lower bail or release the defendant altogether.

Also, CrR 3.2 allows release of defendants to the care of willing and responsible members of the community, including family members. Also, judges may be persuaded to impose other pretrial release conditions such as mandatory curfews, staying away from businesses serving alcohol. Almost everything is negotiable.

AAA Questions Marijuana DUI Laws

Image result for AAA Questions Marijuana DUI Laws

According to a news article from the Chicago Tribune, recent studies conducted by car insurer AAA find that blood tests given to drivers suspected of Marijuana DUI have no scientific basis.

A handful of studies released by the AAA Foundation for Traffic Safety found that drivers can have a low level of THC, the active ingredient in marijuana, in their blood and be unsafe behind the wheel, while others with relatively high levels may not be a hazard. Below are the individual studies accompanied by capsule summaries comprising the effort:

“If you’ve had marijuana whether it’s medicinal or otherwise, don’t drive,” said AAA Chicago spokeswoman Beth Mosher, “It’s really that simple.”

The studies examined the results of more than 5,300 people nationwide who were arrested for driving under the influence of marijuana, 600 of whom tested positive for THC only, while the others had THC and other substances. This is because marijuana isn’t metabolized by the body in the same way as alcohol. The researchers compared the Drug Recognition Expert (DRE) exam results of 602 drivers that only had THC present in their blood at the time of arrest to those of 349 volunteers that took the test drug-free and sober. Ultimately, the degree to which a driver is impaired by marijuana use depends a lot on the individual, the foundation said.

The data appears confusing because AAA also looked at Washington – one of the first states to legalize marijuana – and found fatal crashes involving drivers who recently used marijuana doubled.

“ In most recent data 1 in 6 drivers who are involved in a fatal crash there had marijuana in there system,” Mosher  said.  “And as more and more states look at legalizing marijuana we see this as a concerning trend.”

Nevertheless, AAA is sending the message that the legal limits established for marijuana are arbitrary. A handful of states have moved to specify the maximum amount of active THC — the main chemical in marijuana — that drivers can have in their system. But AAA says that doesn’t work.

“We think those are meaningless,” said Mosher. “They are not backed by any science. One person can have one limit of THC in their blood and be significantly impaired and others can have that same limit and not be impaired at all,” Mosher said.

Many in law enforcement and AAA say that officer recognition of impaired drivers is really the only what to determine whether someone is too high to drive.  Of course all of this a public safety concerns as pot becomes legal across the country.

The Neurology of Risky Driving Behavior

Image result for risky driving behavior

A very interesting article from the Association for Psychological Science discusses how a team of Canadian psychological scientists is looking at the personality, cognitive, and neurobiological factors that contribute to reckless driving behavior. By better understanding the patterns of emotional processing and risk perception shown by repeat offenders, the researchers hope to design interventions that more effectively target these subgroups of dangerous drivers.

The evidence certainly exists. According to the article, drunk driving accounts for 35-40% of all driver fatalities in Canada and the United States, and drunk driving crashes kill more than 10,000 Americans every year. Amazingly, an estimated 30% of DUI offenders will continue to drink and drive, even after being arrested and punished.

“Surprisingly, these drivers usually don’t consider themselves as risk takers,” lead author Thomas G. Brown of McGill University said. “If drivers don’t believe they are risky, they will not accept the need to change. On the other hand, if we and they don’t understand their behavior, how can they be expected to change it effectively?”

The study began when Brown and his colleagues recruited four groups of male drivers who had different criminal histories: 36 men with at least two convictions for drunk driving (DUI group); 28 reckless drivers with at least three speeding violations in the past two years (speeders); 27 men with arrests for both DUI and speeding (DWI-speeders); and 47 low-risk drivers with no history of serious traffic offenses (control group).

According to the article, participants completed a battery of personality and impulsivity assessments, ranging from a Big Five personality measure to an executive control task that assessed their sensitivity to punishment and reward. Participants’ cortisol response, a hormonal reaction to stress, was measured by collecting saliva samples before and after they completed a timed mental arithmetic task previously shown to elicit stress.

Even more interesting, participants also completed a session of simulated driving that included driving on virtual highways, merging lanes, turning at intersections, and avoiding pedestrians.

The researchers found that different subgroups of risky drivers had distinctive neurobiological profiles. Compared to the low-risk control group, speeders were prone to making decisions based on thrill-seeking and a need for high levels of stimulation. Repeat DUI offenders, in contrast, had the lowest level of risk-taking behavior while sober.

“One possibility in line with the present results is that once heavy drinking has occurred, more impulsive drivers are more vulnerable to alcohol’s disruptive effects on the behavioral control mechanisms required to avoid DWI,” the researchers explain.

All of the dangerous driving groups exhibited significant blunting in their cortisol stress response compared with the control group. Cortisol, along with other stress hormones, influences cognitive processes that range from risk assessment to encoding emotional memories. These results suggest that dysregulation of the body’s cortisol response could act as a neurobiological marker for risky driving behavior.

“Relative to the other [risky driving] profiles considered here, the profile exhibited by group DUI may be the most amenable to interventions that aim to augment recall of the negative consequences of DUI behavior and pre-emptively decouple alcohol use from driving,” the researchers conclude.

Stated differently, interventions designed to improve drivers’ recall of the negative consequences of drinking and driving are effective for preventing drunk driving. This explains the findings why repeat DUI offenders had the lowest level of risk-taking behavior while sober.

My opinion? The study is interesting, for sure. Not surprisingly, the criminal justice system uses many of these these psychological deterrents to “decouple alcohol use from driving.” When it comes to DUI cases, gaining a worthwhile reduction of the charges often means the defendant obtaining an alcohol/drug evaluation, attending mandatory treatment, attending AA meetings and attending a Victim Impact Panel. Additionally, the financial costs of DUI fines and mandatory ignition interlock devices are constant reminders to DUI offenders that future risky behavior is simply not worth it.

That said, hiring a competent DUI attorney to fight DUI charges might be a worthy endeavor. The basic legal issues surrounding a DUI arrest are (1) whether the stop was lawful, (2) whether there was enough evidence to arrest, (3) whether the officer informed the defendant of Implied Consent Warnings, and (4) whether the defendant either (a) refused the BAC breathalyzer machine or (b) blew over .08 and/or had .05 nanograms of active THC in their blood when pulled over.
