What is Impaired Driving and How Prevalent is the Problem?

May 19, 2021

Drunk (or alcohol-impaired) driving is a scourge that can tragically impact anyone without warning, regardless of how experienced we are behind the wheel or how many precautions we take. Impaired driving accidents and fatalities are entirely preventable, and through education and increased measures by law enforcement we are seeing the number of annual cases thankfully decline. However, many people continue to be senselessly impacted by drunk driving each and every day.

Let’s take a look at some key impaired driving statistics, including the number of car accidents per year, the number of fatalities annually, and the rate at which drunk driving has decreased over the last few decades.

How Does Alcohol Affect/Impair Driving Ability?

The National Highway Traffic Safety Administration (NHTSA) confirms that alcohol is a substance which can reduce the function of the brain and impair thinking, reasoning, and muscle coordination. All of these faculties are essential to safely operating a motor vehicle.

As alcohol levels rise in a driver’s system, the negative effects on the central nervous system increase. Alcohol is absorbed directly through the walls of the stomach and small intestine. It then passes into the bloodstream where it accumulates until finally being metabolized by the liver. A driver’s alcohol level is measured by the weight of the alcohol within a specific volume of blood, known as ‘Blood Alcohol Concentration’ (or BAC).

A driver with a BAC of .08 grams of alcohol per deciliter (g/dL) of blood is at an exponentially higher risk of being involved in a car accident. Given the risk that impaired drivers pose to the general population, it is illegal in all 50 states (as well as the District of Columbia and Puerto Rico) to drive with a BAC of .08 or higher. In Utah, the BAC limit is .05.

According to the NHTSA, even a minute amount of alcohol can affect one’s driving ability. In 2018, there were reportedly 1,878 people killed in alcohol-related crashes where drivers had lower alcohol levels (BACs of .01 to .07 g/dL). That means some of those drivers were involved in car accidents after having only one drink.

BAC is measured with a breathalyzer. A breathalyzer is a device that measures the amount of alcohol in a driver’s breath. A blood test can also measure a driver’s BAC.

To better illustrate how even small amounts of alcohol can impair a driver’s abilities, the NHTSA has issued the following chart:

The Effects of Blood Alcohol Concentration

Blood Alcohol Concentration (BAC) in g/dLTypical EffectsPredictable Effects on Driving
 
.02Some loss of judgment; relaxation, slight body warmth, altered moodDecline in visual functions (rapid tracking of a moving target), decline in ability to perform two tasks at the same time (divided attention)
.05Exaggerated behavior, may have loss of small-muscle control (e.g., focusing your eyes), impaired judgment, usually good feeling, lowered alertness, release of inhibitionReduced coordination, reduced ability to track moving objects, difficulty steering, reduced response to emergency driving situations
.08Muscle coordination becomes poor (e.g., balance, speech, vision, reaction time, and hearing), harder to detect danger; judgment, self-control, reasoning, and memory are impairedConcentration, short-term memory loss, speed control, reduced information processing capability (e.g., signal detection, visual search), impaired perception
.10Clear deterioration of reaction time and control, slurred speech, poor coordination, and slowed thinkingReduced ability to maintain lane position and brake appropriately
.15Far less muscle control than normal, vomiting may occur (unless this level is reached slowly or a person has developed a tolerance for alcohol), major loss of balanceSubstantial impairment in vehicle control, attention to driving task, and in necessary visual and auditory information processing

How Many Impaired/Drunk Driving Incidents Happen a Year?

Annual Self-reported Alcohol-impaired Driving Episodes among U.S. Adults, 1993–2014

According to the Centers for Disease Control and Prevention (CDC), over 1 million drivers were arrested for driving under the influence of alcohol or narcotics in 2016. That number equals just 1% of the 111 million self-reported episodes of alcohol-impaired driving among U.S. adults every year (see figure below provided by the CDC).

How Many Deaths are Caused by Impaired/Drunk Driving?

The NHTSA confirms that approximately 28 people die in drunk driving car accidents every day. That equals one impaired-driving fatality every 52 minutes.

In 2016, 10,497 people died in alcohol-impaired driving crashes. Those drunk driving car accidents accounted for 28% of all traffic-related deaths in the United States that year. Additionally, of the 1,233 traffic deaths among children ages 0 to 14 years in 2016, 214 (17%) involved an alcohol-impaired driver.

YearTotal traffic fatalitiesAlcohol-related traffic fatalities% of fatalities from alcohol
201936,09610,14228%
201836,56010,51129%
201737,47310,90829%
201637,80610,96729%

Has Drunk Driving Increased or Decreased?

Has Drunk Driving Increased or Decreased?

In 2019, alcohol-impaired driving deaths reached the lowest percentage since 1982 (when the NHTSA first started reporting data). However, that still means that over 10,000 people were killed in drunk driving car accidents – all of which were preventable.

What Age Group is Most Likely to Drive Drunk/Under the Influence?

A data aggregator website known as The Zebra conducted a survey in 2020 with 1500 American drivers. The drivers were asked to indicate whether or not they recognize the dangers of drunk driving. The findings were rather disturbing, as many drivers – especially those among the Generation Y and Z age groups – seemed to harbor beliefs about impaired driving that are simply not true.

According to the survey by The Zebra:

  • Over a quarter (26.1%) of respondents said it takes 3-4 alcoholic drinks for them to feel unfit to drive, while 6.1% said it takes more than five (as stated earlier, it takes only one).
  • The majority (30.8%) of people believe that after a DUI (driving under the influence citation), a driver should lose their license – but only temporarily.
  • 28.1% of the total group believed it should take two DUIs to lose your license permanently.
  • In data comparable to a 2019 survey, 40.3% of people call a friend or a significant other to pick them up after drinking, while 25.7% use rideshare, and a full 10% actually just walk home. These three options were also the most popular in the 2019 survey.
  • 3.5% of respondents ages 25-34 prefer to use a motorized scooter service (e.g. Bird, Lime) to drive home after a night of drinking instead of a rideshare. That means those respondents actually believe operating a scooter – which can be very dangerous when completely sober – is a preferred option to taking an Uber or Lyft rideshare.
  • Most people are aware of their own personal limits regarding alcohol: 30.5% don’t believe they have a high tolerance and won’t drive after drinking.
  • 18.9% of respondents admit to driving while “buzzed.” 2.1% admitted to driving while “high,” and 5.6% admitted to driving while buzzed and high.

While many of those statistics are troubling, it’s important for all drivers to remember that ‘buzzed driving’ is drunk driving, and those who operate a motor vehicle under the influence of any substance may face serious legal repercussions.

How Prevalent is Marijuana/Cannabis Use Among Drivers?

How Prevalent is Marijuana/Cannabis Use Among Drivers?

The CDC confirms the following statistics:

  • Marijuana/cannabis use is increasing, and 13% of nighttime/weekend drivers are reported to have marijuana in their system.
  • Marijuana users were about 25% more likely to be involved in a crash than drivers with no evidence of marijuana use. However, other risk factors – such as age and gender – may account for the increased crash risk among marijuana users, according to the CDC.
  • Removing alcohol from the equation, drugs (legal and illegal) are involved in about 16% of motor vehicle crashes.

How Can Drivers Practice Responsible Behavior When Drinking?

The NHTSA has outlined specific recommendations for reducing drunk driving accidents. Essentially, planning and preparation for how you’ll get home after a night of drinking can help eliminate many impaired-driving car crashes.

The NHTSA recommends drivers:

  • Plan your safe ride home before you start the party – choose a non-drinking friend as a designated driver.
  • If someone you know has been drinking, never let that person get behind the wheel. Take their keys and help them arrange a sober ride home.
  • If you choose to drink, do not drive for any reason. Call a taxi, a ridesharing service, or a sober friend.
  • If you’re hosting a party where alcohol will be served, ensure every guest leaves with a sober driver.
  • Always wear your seat belt – this is, without question, your best defense against impaired drivers.

Additionally, the NHTSA recommends that if you see a potential problem, you take action. If you witness an impaired driver on the road, contact local law enforcement immediately. Failing to take action could lead to another senseless drunk driving tragedy.
