Let’s Prevent Impaired Driving!


Virtually all drivers know that drinking and driving is dangerous. Alcohol impairs judgment, vision, reaction time and muscle control – all abilities required for safe driving.

While drunk driving is on the decline, it remains an epidemic. In 2015, 10,265 Americans were killed in alcohol-related crashes – equivalent to one death every 51 minutes. According to surveys conducted by the AAA Foundation for Traffic Safety, 14% of drivers admit to having driven when they thought their Blood Alcohol Concentration (BAC) was close to or over the legal limit at least once in the past year. In total, alcohol-related crashes cost the public nearly $50 billion annually.

State laws across the country criminalize this behavior. It is a crime to drive in the United States with a BAC at or above 0.08%. Compared with sober motorists, drivers with a BAC of .08% are more than five times more likely to be involved in a fatal crash and four times more likely to be involved in a crash of any severity.

Drivers with a BAC below the legal limit can get a ticket if their ability to drive is impaired. And even one drink can be too much. Compared with sober motorists, drivers with a BAC of .05% are three times more likely to be involved in a fatal crash and twice as likely to be involved in a crash of any severity.

Given these disheartening statistics, there is only one acceptable message for motorists: if you choose to drink, don’t drive. Use a designated driver or an alternate mode of transportation.

Cannabis impairs virtually every driving ability, including cognition, coordination, and reaction time. Drivers impaired by marijuana are more likely to weave within or between lanes and are ill-equipped to respond to unexpected events.

But many drivers aren’t aware of the dangers of combining marijuana and driving. According to surveys conducted by the AAA Foundation for Traffic Safety, only 58% of drivers believe marijuana increases crash risk. As a result, too many drivers are impaired by marijuana: 4.6% of American drivers admit to driving within an hour of using marijuana at least once in the past year.

Marijuana-impaired driving is a significant traffic safety problem – and with more states legalizing recreational marijuana, that problem is growing. Fatal crashes involving marijuana doubled after Washington State legalized the drug (see image).

Alcohol Drug Use Chart By Drivers

Drugged driving is a growing problem. In 2013-14, one in seven weekend nighttime drivers was impaired by an illicit drug – a greater proportion than in previous years.

It is always illegal to drive while under the influence of an illicit drug. Different types of drugs have different effects on drivers – but none of them are positive. Drugs impair judgment, perception, attentiveness, and coordination. And when two drugs are taken together, the combined effect may be worse than the sum of its parts.

Prescription/Over the Counter Medications

When people think of impaired driving, they usually think of driving under the influence of alcohol, marijuana, or illicit drugs. But prescription and over-the-counter drugs can also negatively affect a driver’s ability to operate a vehicle.

Some labels warn drivers not to “operate heavy machinery” while on a certain medication, and a two-ton car is certainly a heavy machine.

Fortunately, the AAA Foundation for Traffic Safety has developed Roadwise Rx, a free resource that drivers can use to see how their medications can impact their ability to drive. Simply type in the names of your medications and Roadwise Rx will display potential side effects as well as interactions with food or other medications.
