When people think about driving under the influence, their thoughts usually turn to drinking and driving. However, there are other types of intoxication that fall under the DUI umbrella. In fact, any drug use, including medicinal marijuana and certain prescribed drugs, can constitute a DUI. The following information can help you better understand the laws as they pertain to driving under the influence in Illinois.

Alcohol Intoxication

Alcohol intoxication while driving is the most prevalent and well-known DUI. It is also the easiest type of intoxication to detect. From the first drink, alcohol starts to affect a person’s coordination, judgement, and reaction time. By the time you reach the legal limit (0.08 in Illinois), your vision is also often impaired. At this point, you are also 11 times more likely to be killed in a single driver crash than a sober driver. Time is the only way to ensure you do not exceed the legal limit. On average, it is about an hour per drink. However, the metabolism of the person, the type of drink consumed, gender, and other factors may increase this time limit.
