Drivers are required to obtain CDL endorsements in order to operate certain types of vehicles. The FMCSRs identify these endorsements with a code (single capital letter) and include: T (double/triple trailers), P (passenger vehicles), N (tank vehicles), H (vehicles required to have identification indicating there are hazardous materials on board), S (school buses), and X (combination of N and H endorsements). These endorsements are the only ones identified by the FMSCA but an individual state may have more. In order to get endorsement for any of the ones listed, a driver must pass a knowledge test. In addition to a knowledge test, S and P endorsements require a skills test. Further, a background check is required for H endorsement.

While endorsements allow operation of certain type of vehicles, the FMCSA has also outlined eight restrictions that prevent certain types of operations. Like endorsements, these restrictions are identified with a code. They include: E: if a driver performs the skills test in an automatic transmission vehicle, he or she cannot operate a CMV equipped with manual transmission; K: if a driver is not qualified to driver interstate, he or she is restricted from driving outside the state; L: if a driver either fails the air-brake component of the knowledge test or performs the skills test in a vehicle not equipped with air brakes, he or she cannot operate a CMV with air brakes; M: if a driver performs the skill test in a Class B vehicle, he or she cannot operate a Class A vehicle; N: if a driver performs the skill test in a Class C vehicle, he or she cannot operate a Class A or B vehicle; O: a driver who did not perform a skills test in a tractor-trailer combination connection by a fifth wheel cannot operate one; V: a driver who was issued a medical variance has to have a restriction code “V” in their driver’s record; Z: if a driver performs the skills test in a vehicle with air-over-hydraulic brakes, he or she cannot operate a vehicle with any braking system operating fully on the air-brake principle.
