Commercial Driver Handbook

CDL Classes in Nevada Now, there are two types of commercial driver’s licenses in Nevada:

  • CDL Endorsements in Nevada In Nevada, there are 6 endorsements, namely:

    • P — for large passenger vehicles
    • S — for school buses
    • N — for tank vehicles
    • H — for vehicles carrying hazardous materials
