Impaired Driving


Previous  
“Impaired driving” refers to the problem of driving under the influence of either alcohol or drugs — or both. Also known as “drunk and drugged driving,” it is a violent crime that can transform a vehicle into a deadly weapon.

The Impact Of Impairment

  • There are six muscles attached to the eye. Alcohol and drugs affect those muscles, making it more difficult to focus. That is why many very intoxicated individuals see double — if they can see at all.
  • Alcohol diminishes night vision.
  • When your eyes are out of sync, the visual information flowing to your brain (for example, judging distance) is flawed.

Some individuals build up a physical dependency in their system and do not necessarily appear to be intoxicated when they are. They confuse these conditions with being sober. But the simple facts are that alcohol impairs an individual’s coordination, vision, reaction time and judgment — and that alcohol mixed with driving can create a deadly combination.

Blood Alcohol Concentration

“Driving under the influence” (DUI) or “driving while intoxicated” (DWI) are based on Blood Alcohol Concentration (BAC), tests that accurately measure the amount of alcohol in your body. BAC is used to determine the level of intoxication and is the basis for enforcement and prosecution of the laws designed to deal with impaired driving.

Alcohol Processing

One drink results in a measurable BAC.

One drink equals:
  • One 12-ounce beer.
  • One 5-ounce glass of wine.
  • 1½ ounces of 80 proof liquor.
Myth Vs. Fact: Preventatives And Cures

Fact
Eating food while you drink will prevent you from getting drunk or makes you get drunk more slowly. Eating before and during drinking slows down the body's absorption of alcohol; however, it is impossible to keep alcohol out of the bloodstream.

Drinking coffee and/or taking a cold shower can help you sober up quickly.

There are no short cuts to sobering up; there is no way to increase the oxidation rate — the rate at which the body naturally eliminates alcohol. Time is the only way to sober up.

Common signs of impaired driving

  • Making wide turns.
  • Straddling the center line.
  • Weaving across the road.
  • Stopping abruptly.
  • Making illegal turns.
  • Swerving from a generally straight course.
  • Driving into oncoming traffic.
  • Braking erratically.
  • Driving slower than 10 mph under the speed limit.
  • Narrowly missing an object or other vehicle.
  • Responding slowly to traffic signals.

If you suspect that a driver is impaired:

  • Be prepared to take action.
  • Keep your distance from the vehicle.
  • If the vehicle is headed toward you, pull to the right, stop, honk your horn and flash your lights.
  • Do not try to intervene. Call 9-1-1. Have the vehicle license number, vehicle description and location of the vehicle, or the direction in which the vehicle was traveling.

Protect yourself and others

  • Do not drink and drive.
  • Do not take drugs and drive. In addition to illegal drugs, some over-the-counter medications and common prescriptions can impair your driving skills. Know the side effects of any medications you are taking.
  • If you do drink, select a “designated driver.” You can also take a cab home.
  • Do not let your friends drive if you know they have been drinking. Ensure they get a safe ride home.
  • Never get into a vehicle with someone who is impaired.
  • Avoid traveling on rural roads.
  • Avoid traveling after midnight, especially on the weekends.
