About the New Jersey Doubles and Triples Test
Topics Covered
- ✓Coupling and uncoupling procedures — NJ examiners want the exact sequence, especially when you're on a grade at a port terminal.
- ✓Trailer stability and sway control — on the Turnpike, a sudden gust near Exit 13 can push your rear trailer into the next lane; you need to know how to counter it.
- ✓Off-tracking and turning radius — longer doubles cut corners wider, and NJ's tight cloverleaf ramps don't forgive mistakes.

📘 Study Tips & State Info
NJ examiners are sticklers for the coupling sequence. They'll ask you what comes first, second, third — and they'll throw in a question about what to do if the glad hands don't match. Memorize the order from the New Jersey CDL manual. Don't skip the step about checking the height of the fifth wheel or pintle hook.
Trailer sway questions are common. The manual talks about speed, weight distribution, and tire pressure. In New Jersey, crosswinds on the Turnpike are a real problem. Think about how you'd handle a set of doubles when the wind is gusting near the Bayonne Bridge. That mental connection helps the answers stick.
One more thing: the test includes questions about emergency equipment. NJ requires three red reflective triangles for any combination vehicle. Know where to place them. Also know the rule about not using flares near flammable cargo — that's a common gotcha.
New Jersey MVC handles all CDL testing. You must make an appointment online or by phone for the written knowledge tests. Walk-ins are not guaranteed. Bring your valid driver's license, Social Security card, proof of residency, and a valid Medical Examiner's Certificate (DOT physical). The fee for a CDL permit is $125, which includes the General Knowledge test and up to two endorsements. Adding Doubles and Triples as a separate endorsement costs an additional $10.
Testing locations that offer CDL written tests include the Trenton MVC, Lodi MVC, and the Eatontown agency. Not all locations handle CDL endorsements, so check the NJ MVC website before you go. The Doubles and Triples test is taken on a computer at the agency. You'll get your score immediately.
One unique rule in New Jersey: you can't take the skills test until you've held your CLP for at least 14 days. And if you fail the Doubles and Triples written test, you can retake it the next business day, but you'll pay the $10 fee again each time.
About the New Jersey Doubles and Triples Test
If you're planning to pull doubles or triples in New Jersey, you already know this isn't flat, open country. You're dealing with the New Jersey Turnpike's constant curves, tight exit ramps at exits like 8A and 11, and crosswinds that'll push a set of doubles into the next lane. The Doubles and Triples endorsement test makes sure you can handle that.
This test is separate from the Combination Vehicles test. You need to pass it if you want to tow more than one trailer. It covers coupling and uncoupling procedures, how to prevent trailer sway, and how to manage the extra length when you're squeezing through Newark's industrial roads or backing into a loading dock in Elizabeth.
The test has 20 multiple-choice questions. You need 16 right to pass — that's 80%. You'll take it at a New Jersey MVC location that does CDL testing, like the ones in Trenton or Lodi. Bring your permit and medical certificate.
New Jersey's port industry means a lot of doubles and triples work around the Port of Newark and Elizabeth. If you're driving out of there, you'll face tight spaces, heavy traffic, and constant coupling and uncoupling. This test isn't just a hoop to jump through — it's the knowledge you'll use every shift.
