Driving a commercial motor vehicle is a big responsibility. It requires special skills and knowledge. Most drivers must obtain a commercial driver’s license (CDL) through their home State (it is illegal to have a license from more than one State). In addition, special endorsements may be required if you or your company drivers will be driving any of the following vehicles:

• a truck with double or triple trailers
• a truck with a tank
• a truck carrying hazardous materials
• a passenger vehicle

Contact your State licensing bureau (e.g., Department of Motor Vehicles) for details.
