IL defense lawyerAcross the United States, drivers with standard driving licenses must maintain a blood alcohol content (BAC) below 0.08 percent. The standard is higher for commercial drivers, who, along with having to pass rigorous testing to get a commercial driver’s license (CDL), are also legally required to have a BAC below 0.04 percent.

If you have been charged with a DUI, you will want to do everything in your power to avoid a conviction. That begins with reaching out to an experienced Arlington Heights DUI defense lawyer to defend you.

Legal BAC for a Commercial Driver

The Federal Motor Carrier Safety Administration and Illinois law state that a commercial driver has committed a violation if the individual has a BAC of 0.04 percent or higher while operating a commercial motor vehicle.  

Testing may be performed by taking a blood, urine, or breath sample. Be aware that, under the law, driving under the influence does not just include alcohol. You can be charged for driving under the influence if you have smoked marijuana, methamphetamine, or other illicit drugs. Any of these substances have the potential to impair your driving.
