What major traffic offenses disqualify non-CDL drivers?

Drivers who are not required to hold a Class A, B, or C commercial driver’s license (CDL) will be disqualified if convicted for the following offenses:

• Driving a commercial motor vehicle (CMV) while having an alcohol concentration of 0.04 percent or more;
• Driving a CMV under the influence of alcohol, as prescribed by state law;
• Refusing to undergo an alcohol test required by law;
• Driving a CMV under the influence of a controlled substance;
• Transporting, possessing, or unlawfully using a controlled substance while on duty;
• Leaving the scene of an accident;
• Committing a felony involving the use of a CMV;
• Violating an out-of-service order;
• Violating a prohibition on texting while driving a CMV; or
• Violating a prohibition on using a hand-held mobile telephone while driving a CMV.

To be a disqualifying offense, the violation must have occurred in connection with operating a “commercial motor vehicle” as defined in 49 CFR §390.5 (Note: drivers of vehicles required to be placarded for hazardous materials fall under this definition, but are also required to hold a CDL).

The disqualification of non-CDL drivers is outlined in §391.15.
