Impaired Driving

DPS Patrol CarOverview on Impaired Driving

Impaired driving can be defined as a reduction in the performance of critical driving tasks due to the effects of alcohol or other drugs.

"You Drink & Drive. You Lose" and "Friends Don’t Let Friends Drive Drunk." These national slogans discourage impaired driving and are familiar to millions of Americans. And the message is getting through to the public. In 1982, 57% of motor vehicle fatalities were alcohol-related. In 2002, that number had fallen to 41%. However, the fight is far from over.

In Arizona in 2001, 488 people died in motor vehicle crashes where alcohol was a factor. Thousands more were injured. Alcohol-related crashes are painful and expensive. Costs to treat the injured are passed on to taxpayers in the form of increased public health costs and higher insurance premiums. When it comes to impaired driving, everyone loses.
