Repeat DUI Offenses in Chicago
02/21/2026
Illinois implemented the 0.08 driving under the influence (DUI) law in July 1997. This DUI law lowered the maximum amount of blood alcohol concentration (BAC) from 0.10 to 0.08. Illinois became the 25th state in the U.S. to implement the DUI law. Today, all 50 states adhere to and enforce this law. In 1997, the death toll of drunk driving-related fatalities was at an alarming 534. As of 2015, that number has barely risen over 300, causing a 43% reduction of drunk driving deaths in Illinois. While this number may seem large, Illinois DUI statistics have greatly improved in recent years.
Driving under the influence of alcohol and drugs has severe consequences that are emotionally, financially, and physically taxing for any driver.

In Illinois, the typical DUI offender is overwhelmingly male. Men represent approximately 75% of the total DUIs. Also, the average DUI offender is 34 years old, and DUI offenders aged 35 or less represent approximately 57% of total DUIs. In 2017, in Illinois, police officers arrested 27,046 DUI offenders. Further, most drunk driving arrests were made between 11 pm and 4 am. The average blood alcohol content (BAC) was 0.16, which is twice the legal limit anywhere. Also, 91% of DUI offenders lost their driving privileges, and 86% of intoxicated drivers were first-time DUI offenders.

Unfortunately, some drivers still make the terrible decision to drive while drunk. This can lead to severe consequences, much more serious than just going to jail. In the United States, driving under the influence of drugs or alcohol is still a big problem.
Since the 1980s, new DUI laws about the minimum legal drinking age reduced alcohol consumption and impaired driving among young adults. However, intoxicated driving still causes too many traffic fatalities every year. The National Highway Traffic Safety Association (NHTSA) reports that 28 people per day still die from drunk driving car accidents. Across the nation, some states are more severely affected than others when it comes to the most DUIs. North Dakota has the highest DUI percentage at 5.17 percent, and it also reports the highest rate of binge drinking in the nation.
If we look at drunk driving deaths per 100,000 people, Wyoming tops the list with 7.60 fatalities per 100,000 people.
Here are more drunk driving statistics across the nation, according to the Centers for Disease Control and Prevention (CDC):

Driving under the influence of drugs or alcohol is a crime, and there are severe legal penalties and economic consequences if convicted. It’s essential to note that the DUI criminal charge is prosecuted in criminal court and the Secretary of State’s office administers driver’s license sanctions.
