What Is DUI in Chicago?

DUI stands for driving under the influence. Whether you are driving under the influence is usually determined by your blood-alcohol content, or BAC.

A BAC of .08 or above is considered a per se DUI in Chicago. This means that your blood contains eight one-hundredths of a percent of alcohol. If you test at .08 or above, you will automatically be arrested for committing DUI.

However, if you test under .08, you can still be arrested for committing DUI. If the officer believes your driving has been impaired due to consumption of drugs or alcohol, he may still arrest you for DUI even though your BAC is under .08. However, it will be much more difficult for the state to prove its case against you. Under such circumstances, a Chicago DUI lawyer may be able to help you avoid a conviction.

The BAC limit is different for certain individuals. Chicago has a zero-tolerance policy regarding those under the age of 21 who drink and drive. This means that if you are under 21 and are caught driving with any amount of alcohol in your system, you may be arrested for committing DUI in Chicago.

  • Five days to one year in jail
  • Fines up to $2,500
  • License suspension for at least five years

A third DUI offense is considered a class 2 felony. If charged, you may face:

  • Three to seven years in prison
  • Fines of up to $2,500
  • License suspension of 10 years minimum

The Chicago DUI Process

An officer may pull you over for a number of reasons, including:

  • Committing a traffic violation
  • Driving suspiciously or erratically
  • Entering a sobriety checkpoint zone. A sobriety checkpoint is a predetermined location where officers pull over random drivers and check them for driving under the influence.

Once the officer has pulled you over, he may administer a field sobriety test to determine if you are impaired. Common field sobriety tests include:

  • Following a light with your eyes while keeping your head and neck stationary
  • Standing on one leg
  • Walking in a straight line, turning and walking back

If you do poorly on the field sobriety test, the officer may place you under arrest. He will then take you back to the police station for BAC testing.

There are a number of ways to test your BAC. One of the most common methods is the breathalyzer. A breathalyzer is a device that can measure your BAC based on the alcohol content of your breath. In Chicago, breathalyzer tests are not mandatory. However, if you refuse to take the test, you may face severe punishment, including immediate license suspension.

If your BAC is .08 or above, you will be charged with DUI.
