A driver's license in Illinois may be suspended if breath, blood or urine testing indicates:

In Illinois, the law establishes that a driver's license can be suspended if any form of chemical testing—breath, blood, or urine—indicates a violation of the state's legal blood alcohol concentration (BAC) limits. This means that if any one of these tests shows a BAC at or above the established threshold, it is sufficient for suspension.

The legal framework aims to ensure safety on the roads by actively monitoring impaired driving through all available testing methods. Therefore, it does not limit the suspension to just one type of test or a specific threshold from one source. All methods are valid, and each can result in the same consequence if they show evidence of exceeding the legal limits for alcohol or drugs. This comprehensive approach reinforces the importance of responsible driving and the measures taken to prevent impaired operation of vehicles.
