Your license class says what you may drive. Most new drivers get Class C, and motorcycles need Class M. Restriction codes are letters printed on the license that limit when or how you may drive.

Know the rule

Class C lets you drive a single vehicle or combination (except motorcycles) with a GVWR less than 26,001 pounds, or such a vehicle towing one with a GVWR of no more than 10,000 pounds.
