3 min read

Commercial drivers in New Hampshire can expand their opportunities and meet specific job requirements by adding endorsements to their CDL. Each endorsement allows the operation of additional vehicle types or authorizes the transport of certain cargo under federal and state regulations.

What Are CDL Endorsements?

CDL endorsements are additional certifications on your commercial license, requiring knowledge or skills testing to operate specialized vehicles or transport specific materials legally. Common endorsements in New Hampshire include:

  • H (Hazardous Materials): Required for transporting hazardous materials; involves a TSA background check and a written knowledge test.
  • N (Tank Vehicles): Allows operation of tank vehicles transporting liquids or gases.
  • P (Passenger): Permits transporting passengers in buses.
  • S (School Bus): Required to operate a school bus and includes a background check.
  • T (Double/Triple Trailers): Required for towing multiple trailers.
  • X (Combination of Tank and Hazardous Materials): For those transporting hazardous materials in tank vehicles.

Testing and Application Process

To add an endorsement, you must:

  1. Pass the required written knowledge test for the specific endorsement.
  2. Pass a skills test if adding a passenger or school bus endorsement.
  3. Complete a TSA background check for hazardous materials endorsements.
  4. Pay applicable fees for adding endorsements.

You can schedule your endorsement testing by visiting your local DMV office or booking an appointment online.
