Every day, 29 human being in the United claims die in motor automobile crashes the involve an alcohol-impaired driver.1 This isone fatality every 50 minutes.1 The yearly cost the alcohol-related crashes totals much more than $44 billion.2

Thankfully, there are efficient measures that can assist prevent injuries and deaths from alcohol-impaired driving.

You are watching: Approximately 40 of fatal highway crashes are alcohol-related

How huge is the problem?

In 2016, 10,497 civilization died in alcohol-impaired control crashes, audit for 28% of all traffic-related deaths in the joined States.1Of the 1,233 traffic deaths among children periods 0 come 14 years in 2016, 214 (17%) affiliated an alcohol-impaired driver.1In 2016, much more than 1 million motorists were arrested because that driving under the affect of alcohol or narcotics.3 That’s one percent of the 111 million self-reported episodes of alcohol-impaired driving among U.S. Adults every year (figure below).Drugs other than alcohol (legal and also illegal) are associated in around 16% that motor vehicle crashes.4Marijuana customers were around 25% an ext likely come be involved in a crash than drivers with no proof of marijuana use, but other factors–such together age and also gender–may account because that the raised crash risk among marijuana users.4

Annual Self-reported Alcohol-impaired steering Episodes amongst U.S. Adults, 1993–2014


Source: cg-tower.com. Behavioral Risk factor Surveillance mechanism (BRFSS), 1993–2014. Easily accessible at https://www.cg-tower.com/brfssNote: The annual estimated alcohol-impaired driving episodes were calculated making use of BRFSS respondents’ answers come this question: “During the past 30 days, how plenty of times have you driven once you’ve had perhaps too lot to drink?” annual estimates every respondent to be calculated by multiplying the reported episodes throughout the preceding 30 job by 12. These numbers were summed to attain the yearly national approximates (see https://www.cg-tower.com/mmwr/preview/mmwrhtml/mm6430a2.htm).

Who is many at risk?

Young people:

At all levels that blood alcohol concentration (BAC), the danger of being affiliated in a crash is better for young civilization than because that older people.6Among vehicle drivers with BAC level of 0.08% or higher involved in deadly crashes in 2016, practically three in 10 were in between 25 and also 34 year of age (27%). The next two largest teams were ages 21 come 24 (26%) and 35 come 44 (22%).1


Among motorcyclists killed in deadly crashes in 2016, 25% had actually BACs the 0.08% or greater.1Motorcyclists periods 35-39 have the highest possible percentage the deaths v BACs that 0.08% or greater (38% in 2016).7

Drivers through prior driving when impaired (DWI) convictions:

Drivers through a BAC of 0.08% or greater involved in fatal crashes were 4.5 times an ext likely to have a front conviction because that DWI than were motorists with no alcohol in their system. (9% and 2%, respectively).1

What space the results of blood alcohol concentration (BAC)?

Information in this table shows the blood alcohol concentration (BAC) level in ~ which the effect usually is very first observed.

Blood Alcohol Concentration (BAC)*Typical EffectsPredictable effects on Driving
.02%About 2 alcoholic drinks**Some loss of judgmentRelaxationSlight body warmthAltered moodDecline in visual functions (rapid tracking of a relocating target)Decline in capability to perform two tasks at the very same time (divided attention)
.05%About 3 alcoholic drinks**Exaggerated behaviorMay have loss of small-muscle regulate (e.g., concentrating your eyes)Impaired judgmentUsually good feelingLowered alertnessRelease the inhibitionReduced coordinationReduced capacity to track relocating objectsDifficulty steeringReduced response to emergency driving situations
.08%About 4 alcoholic drinks**Muscle coordination becomes bad (e.g., balance, speech, vision, reaction time, and also hearing)Harder to detect dangerJudgment, self-control, reasoning, and memory are impairedConcentrationShort-term storage lossSpeed controlReduced information processing ability (e.g., signal detection, intuitive search)Impaired perception
.10%About 5 alcoholic drinks**Clear deterioration of reaction time and controlSlurred speech, poor coordination, and slowed thinkingReduced capability to keep lane position and brake appropriately
.15%About 7 alcoholic drinks**Far less muscle regulate than normalVomiting may take place (unless this level is reached progressively or a human has emerged a tolerancefor alcohol)Major loss of balanceSubstantial handicap in vehicle control, attention to steering task, and in important visual and also auditory details processing

*Blood Alcohol Concentration Measurement

The number of drinks listed represents the approximate amount the alcohol the a 160-pound man would must drink in one hour to reach the provided BAC in every category.

**A traditional Drink dimension in the unified States

A typical drink is equal to 14.0 grams (0.6 ounces) that pure alcohol. Generally, this amount of pure alcohol is found in

12-ounces of beer (5% alcohol content)8-ounces the malt liquor (7% alcohol content)5-ounces of alcohol (12% alcohol content)1.5-ounces or a “shot” of 80-proof (40% alcohol content) distilled spirits or liquor (e.g., gin, rum, vodka, whiskey)

How deserve to deaths and injuries indigenous impaired driving it is in prevented?

Effective procedures include:

Actively enforcing existing 0.08% BAC laws, minimum legitimate drinking age laws, and also zero tolerance legislations for vehicle drivers younger 보다 21 years old in every states.4,8Putting health and wellness promotion efforts into practice that influence economic, organizational, policy, and also school/community action.11,12Using community-based philosophies to alcohol control and DWI prevention.8,12,13Requiring mandatory problem abuse assessment and also treatment, if needed, because that DWI offenders.14Raising the unit price the alcohol by raising taxes.15

What security steps can individuals take?

Make to plan so the you don’t need to drive if impaired by alcohol and/or drugs. For example:

Before drinking, point out a non-drinking driver as soon as with a group.Don’t let your friends drive while impaired.If you have actually been drink alcohol and/or making use of drugs, obtain a journey home, usage a ride share service, or speak to a taxi.If you’re hosting a party where alcohol will certainly be served, remind your guests to plan ahead and also designate a sober driver. Offer alcohol-free beverages, and also make certain all guest leave through a sober driver.
