About the Maine Doubles and Triples Test
Topics Covered

📘 Study Tips & State Info
The Maine CDL handbook is your starting point, but don't just read it — picture yourself at a paper mill in Jay, backing a set of doubles up to a loading dock in the rain. Maine examiners love questions about the order of operations for coupling. They'll ask you when to connect the air lines, when to crank the dolly, and when to test the brakes. Mixing up that sequence is a common fail point.
Another thing: Maine's testing office in Augusta has a reputation for asking about emergency procedures. They want to know you can handle a trailer breakaway on a downgrade in the snow. Study the section on what to do if your trailer's emergency brakes activate. And know the difference between spring brakes and service brakes for the dolly.
Take our practice tests in timed mode. You get 25 minutes on the real exam, and the pressure can throw you off. Get comfortable answering quickly. If you can score 90% here three times in a row, you're ready for the real thing.
The Maine Bureau of Motor Vehicles (BMV) handles all CDL testing. You can take the Doubles and Triples written test at any BMV office that offers CDL services — the main ones are in Augusta, Bangor, Portland, and Scarborough. Appointments are strongly recommended; walk-ins are allowed but you might wait hours. Schedule online at maine.gov/sos/bmv or call your local office.
You'll need to bring your commercial learner's permit (CLP), a valid medical examiner's certificate, and proof of identity. The fee for the written knowledge test is $30 per endorsement. If you fail, you can retake it the next business day — no waiting period. The test is only offered in English.
Maine has a specific restriction: if you get your Doubles and Triples endorsement, you can only pull doubles and triples on routes designated by the state. Those include interstates and certain US highways. You can't run them on secondary roads unless you have a special permit. Make sure you know the route restrictions before you take the wheel.
About the Maine Doubles and Triples Test
If you're pulling doubles or triples in Maine, you're not on some flat interstate in the middle of nowhere. You're on I-95 between Bangor and Houlton in January, or hauling wood chips out of a paper mill in Rumford. The Maine Doubles and Triples endorsement makes sure you can handle those conditions safely.
This test is part of the Class A CDL written exam. You take it after passing General Knowledge and Combination Vehicles. It's 20 multiple-choice questions, and you need 16 right to pass. The questions focus on the stuff that matters for Maine drivers: coupling and uncoupling in the cold, keeping your trailers stable on icy grades, and managing off-tracking on narrow two-lane roads.
Maine allows doubles and triples on designated highways — mostly interstates and some US routes. You won't be running them on Route 1 through Camden, but you will see them on I-295 near Portland and on the Maine Turnpike. The state's winter weather adds a layer of challenge that the test specifically addresses: how to adjust your braking distance, how to prevent trailer sway in crosswinds, and what to do when black ice catches you on a curve.
Our practice test mirrors the real BMV exam. You'll see questions about converter dolly safety, air line hookups, and emergency procedures for a trailer breakaway. Take it a few times until you're scoring 90% or better. That's how you walk into the BMV office and pass the first time.
