A 1995 study for General Motors/Prevention magazine, “Auto Safety in America,” highlighted these findings:

 ·         One in five drivers sometimes drives after drinking.  Easterners, men and those with higher incomes and educational levels are most likely to drive after drinking.

·         Easterners are most likely to drive after drinking; those in the South are least likely to do so.

·         Men are twice as likely as women are to drive after drinking.  28% of men admit to this unsafe behavior compared to just 14% of women.

·         People aged 30 to 39 years are the most likely to drive after drinking while those over 65 are least likely to do so.

·         The more education people have and the higher their annual household income, the more likely they are to drink and drive.  College graduates are more than three times as likely to drive after drinking than those without high school diplomas; people with household incomes of $50,000+ drive after drinking at more than double the rate of those with incomes below $15,000.

 

Alcohol is a drug, a depressant that affects the entire nervous system.  Regardless of the drink: beer, wine or distilled spirits, the chief components are ethanol and water.  The typical drink contains about three-fourth of an ounce of alcohol - one 12 ounce beer that has 5% alcohol, one 5 ounce glass of table wine that is 12% alcohol, or one shot (1.5 ounce) of 80 proof distilled spirits.  All of these drinks have about the same amount of alcohol.

When alcohol is ingested, approximately 5% enters the blood stream directly through the mouth and throat tissues.  The largest percentage, approximately 80% is absorbed by the small intestine after passing through the stomach.  Alcohol distributes itself throughout organs and tissues in proportion to their fluid content, concentrating more quickly in organs with large blood supplies like the brain and the liver.  Alcohol cannot be stored in tissue and less than 10% is eliminated by the kidneys, lungs and skin.  Approximately 2 – 5% is passed unchanged through urine, breath and sweat.  The liver eliminates the other 90% through the process of oxidation.  The liver can eliminate approximately one drink per hour.

Common signs of an impaired driver are:

 

·         Unreasonably high speed

·         Inconsistent driving speeds

·         Frequent lane changing at excessive speeds

·         Improper passing with not enough room to pass, slow driving or excessive swerving when overtaking or passing

·         Overshooting or disregarding traffic control signals

·         Approaching a signal at unreasonable speed, too fast or too slow

·         Stopping or attempting to stop with an uneven motion

·         Driving at night without lights

·         Failure to dim lights to on-coming traffic

·         Jerky starts or stops
