New Hampshire Class B to Class A Upgrade Study Material Overview

Upgrade prep for Class B CDL holders moving to Class A, including combination vehicles, coupling, air brakes, and HOS theory.

Class B to Class A Upgrade for New Hampshire CDL Applicants

New Hampshire connects New England freight networks and serves growing distribution needs in the Manchester corridor. With electronics and manufacturing, granite and construction materials, tourism and resort supply driving much of the freight in New Hampshire, the Class B to Class A Upgrade material below is the part of the New Hampshire CDL that those employers screen for first.

The New Hampshire Class B to A upgrade: Combination Vehicles and Air Brakes knowledge tests at New Hampshire Division of Motor Vehicles, then a Class A skills test. Since February 2022, ELDT theory and behind-the-wheel training must also be logged with an FMCSA-registered provider before New Hampshire Division of Motor Vehicles will schedule the test.

Where New Hampshire drivers use this

  • Almost every Class A and Class B vehicle in New Hampshire; skip this test and your CDL carries an L restriction
  • Electronics and manufacturing: dry-van and flatbed freight between manufacturers, suppliers, and distribution centers
  • Tourism and resort supply: event, production, and resort supply freight
  • Healthcare distribution: regional and over-the-road distribution runs for grocery, retail, and e-commerce freight
  • Electronics and manufacturing: regional and over-the-road tractor-trailer distribution runs

Most New Hampshire CDL work runs the I-89, I-93, I-95 corridors and the Concord area, so the examples in the practice questions lean on the vehicles and loads you will see there.

Testing, appointments, and fees are handled by New Hampshire Division of Motor Vehicles. See the New Hampshire CDL classes and New Hampshire endorsements pages for the full licensing picture.

Topics Covered for New Hampshire Class B to Class A Upgrade Study Material

Combination Vehicle Dynamics

Upgrading from Class B to Class A means operating vehicles with fundamentally different handling. Off-tracking, rearward amplification, and trailer swing all require new driving habits. The Combination Vehicles written test focuses on these differences compared to single heavy vehicles.

Coupling and Uncoupling Procedure

Correctly connecting a tractor to a trailer is a critical Class A skill tested both on the written exam and during the skills test. This module covers the exact coupling sequence that examiners expect to observe during the pre-trip exercise.

Air Line Connections

Class A combination vehicles use service and emergency air lines between the tractor and trailer that Class B drivers have not typically operated. You will learn how to connect them correctly, perform pressure checks, and identify warning signs of failure.

New Hampshire CDL Trailer and Coupling Inspection

Adding a trailer to your pre-trip inspection means covering the coupling area, fifth wheel, air connections, trailer brakes, and landing gear in sequence. The Class A skills test expects you to demonstrate all of these additional inspection points.

New Hampshire CDL Class A Test Readiness

The Class A upgrade requires passing the Combination Vehicles written knowledge test plus completing a new skills test on a Class A vehicle. This section prepares you for the content differences, scoring criteria, and what Class A evaluators assess differently from Class B.
