About the New Hampshire Combination Vehicles Test

Combination vehicles handle differently than straight trucks. You'll face tight curves on Route 16 and steep descents on I-93 through Franconia Notch. New Hampshire's winter weather makes skid control a must-know. Our test focuses on NH-specific issues like mountain grades and logging truck safety.

We pull questions straight from the New Hampshire CDL manual. You'll see realistic scenarios involving double and triple trailers, tankers, and hazardous materials. Each question explains why the right answer matters for Granite State drivers. For example, coupling improperly on a frost-heaved road can cause a rollover.

New Hampshire has its own weight restrictions and inspection rules. You must understand axle limits on secondary roads and the state's stricter air brake maintenance schedule. Our test covers these local regulations, so you're ready for both the written exam and real-world driving.

Take this practice test anytime, anywhere. It's free and works on any device. You'll get instant feedback and a score at the end. Use it to find your weak spots before you visit the DMV.

What This Test Covers

  • Coupling and uncoupling – critical for logging trucks on NH's narrow dirt roads where misalignment can cause a crash.
  • Air brake systems – you'll need to manage steep grades on I-93 and I-89, especially in freezing rain.
  • Pre-trip inspection – NH's annual inspection includes combination vehicle components; know every step.
  • Weight and balance – New Hampshire's winter weight restrictions vary by road; avoid overweight fines.
  • Skid control and recovery – black ice on the Kancamagus demands quick, correct reactions.
  • Doubles and triples handling – longer combinations require more space on NH's winding two-lane highways.

Study Tips

Start by downloading the New Hampshire CDL manual from the DMV website. Focus on Chapter 6 – Combination Vehicles. Read the air brake section twice, because it's heavily tested. Make flashcards for coupling steps and pre-trip checkpoints.

Use our practice test to identify what you don't know. Review each wrong answer's explanation. Then take the test again until you score 90% or higher. The real NH test gives you 20 questions and you need 16 correct. We recommend aiming for 18.

On test day, arrive early at the DMV. Bring your learner's permit, medical certificate, and a printed copy of your practice test results (optional). The combination vehicles endorsement costs $40 extra on top of your CDL application fee.

New Hampshire DMV Information

You'll take your combination vehicles written test at any New Hampshire DMV office – Concord, Manchester, Portsmouth, or Nashua are the busiest. Walk-ins are accepted, but appointments speed things up. Schedule online at the NH DMV website or call your local office. The test is computer-based and you get results right away.

Skills testing requires a separate appointment. You'll need to bring your own combination vehicle (or rent one from a school). The test covers pre-trip, basic control, and on-road driving. Fees: $40 for the written endorsement test, plus $100 for the skills test. Don't forget to show your medical examiner's certificate and valid driver's license.

New Hampshire doesn't issue temporary CDL documents. After passing, you'll get a paper permit same day, and your physical card arrives by mail in 7–10 business days. Your combination vehicles endorsement will appear on the card.
