DUI Facts


In Illinois in 2004:

  • 604 people were killed in alcohol-related crashes, which was 44 percent of the 1,356 total crash fatalities.
  • More than 50,147 DUI arrests were recorded by the Secretary of State's office.
  • 92 percent of all drivers arrested for DUI, who were eligible, lost their driving privileges.
  • 2,694 drivers under age 21 lost their driving privileges due to "Use It & Lose It" law violations.
  • 18 percent of those arrested for DUI are women, who represent 50 percent of all licensed drivers.
  • Males ages 21-24 had the highest DUI arrest rate (about 28 per 1,000 licensed drivers). This rate was four times greater than that of all other drivers arrested for DUI (6 per 1,000).
  • 83 percent of all drivers arrested for DUI are first offenders.

Nationally:

  • Alcohol-related crash fatalities totaled 16,694 in 2004.
  • Alcohol-related occupant fatalities decreased 2.4 percent from 2003 to 2004.
  • Drivers with a BAC greater than .08 who were killed in crashes were 10 times as likely to have a prior conviction for driving while intoxicated.

Facts about .08:

  • Illinois' .08 BAC limit was signed into law July 2, 1997. .08 is a measurement of the blood-alcohol concentration level at which drivers are considered intoxicated and, therefore, are prohibited from driving on Illinois roadways.
  • All 50 states, the District of Columbia and Puerto Rico have .08 BAC per se laws.
  • At .08, all drivers are impaired to the point that critical driving skills are greatly diminished. Studies indicate that at a .08 BAC level, a driver's steering, braking, speed control, lane changing, gear changing and judgments of speed and distance are all significantly impaired.
  • To reach .08, a 170-lb. male would have to consume four or more drinks in a one-hour period on an empty stomach. A 137-lb. female would have to consume three drinks in one hour to reach .08. A drink is considered a 12-oz beer, a 5-oz. glass of wine or a cocktail containing 1.5 ounces of 80-proof liquor.
  • At .08, a driver is three times more likely to be involved in a car crash than a sober driver, and 11 times more likely to be killed in a single-vehicle crash.
  • Skeptics of .08 laws suggest that repeat offenders are the “real” problem with regard to drunk driving. However, about 80 percent of alcohol-related crash fatalities are caused by drivers with no arrests for drunk driving during the previous three years.
