Tanker Endorsement (N)
A CDL endorsement required to drive tank vehicles carrying liquid or gas.
Definition
The Tanker (N) endorsement authorizes CDL holders to drive tank vehicles — any commercial vehicle designed to transport liquid or gaseous materials in a permanently attached tank of 1,000+ gallons. The endorsement requires passing a written test covering tank vehicle inspection, driving techniques (surge, stopping distance), and emergency procedures. Combined with the hazmat endorsement (X = H + N), tanker-endorsed drivers earn premium pay.
Why it matters to you
The tanker endorsement covers liquid in bulk, and it changes how the truck behaves — surge can push you through a stop or roll you in a bend that a dry van takes comfortably. You need it for any tank carrying liquid over the threshold quantity, loaded or not. Paired with hazmat it opens fuel and chemical work, which pays a premium for exactly these reasons.
