Driving under the influence (DUI), whether for alcohol, prescription drugs, marijuana, or other intoxicating substances, is a serious offense in Illinois and across the nation.

If you have been arrested on suspicion of DUI and have a CDL, you need an experienced DUI attorney on your side. The skilled attorneys in the law office of Kathryn L. Harry & Associates, P.C. know how to protect your rights and your driving privileges. We have successfully resolved cases for commercial drivers throughout the Chicago area.

DUI Penalties for Commercial Drivers in Illinois

Unlike the DUI blood alcohol concentration level of 0.08 for non-commercial drivers, CDL drivers can be arrested on DUI for any BAC level, especially 0.04 or more. Recently Illinois has expanded the DUI laws affecting CDL drunk drivers, effecting penalties against your commercial driver’s license even if you are arrested for driving a non-commercial vehicle. If you are charged with DUI while driving a non-commercial vehicle and refuse to take a chemical test, and it’s your first offense, your CDL will be disqualified for a year. Your CDL is also disqualified for one year if you are convicted on DUI for alcohol or any amount of cannabis or controlled substance, and it is your first offense, even if you are given supervised probation. Your CDL will be permanently disqualified for a second DUI.

If you hold a CDL and are arrested on DUI, you will incur further charges and penalties if you:

  • Commit a felony while driving
  • Leave the scene of an accident while driving a commercial motor vehicle, or a non-commercial vehicle - 12 month disqualification
  • Violate an out-of-service order - 6 month disqualification
  • Are carrying hazardous materials - 3 year disqualification
  • Use the commercial vehicle in the sale, transport, or distribution of drugs - lifetime disqualification.
  • Have committed two serious traffic violations within a three-year period - 2 month disqualification
  • Have committed three serious traffic violations in a three-year period - 4 month disqualification

Having a conviction for an accident involving death, excessive speeding, speeding in a school zone, reckless driving, driving with an invalid CDL, and having multiple licenses are other serious infractions that will increase your charges and penalties.
