About the New Mexico Doubles and Triples Test
New Mexico's wide-open highways like I-25 and I-10 are prime routes for double and triple trailers. You'll see them carrying oil field equipment, agricultural goods, and freight across the state. But those long combinations behave differently when you hit crosswinds near Raton Pass or dust storms east of Las Cruces.
The New Mexico CDL doubles and triples test covers everything from coupling and uncoupling to safe speed control. You need to know the extra space your rig takes, especially when merging onto busy interstates around Albuquerque. One wrong move with 28-foot pups can shut down a highway.
Our practice test is built from the latest New Mexico CDL manual. You get 20 questions that match the real exam at any MVD office. Each question explains why the right answer matters for New Mexico drivers. No fluff, no filler—just the facts you need.
Passing this test gets you the T endorsement on your CDL. That lets you drive double and triple trailers legally in New Mexico and across the country. Don't risk failing at the MVD. Practice here first.

Study Tips
Study the New Mexico CDL manual's doubles and triples section carefully. Focus on the diagrams for coupling and converter dolly operation. The test pulls specific numbers—like maximum cargo weight before you need a second dolly. Know those.
Schedule your written test at any MVD office. You don't need a reservation for the knowledge test, but bring your CDL permit and a valid ID. The doubles/triples endorsement adds $10 to your license fee. Practice until you score 80% or higher on our test—that's the real passing score.
New Mexico Specific Information
New Mexico MVD offices in Albuquerque, Santa Fe, and Las Cruces offer the doubles and triples written test. Walk-ins are accepted, but you'll wait longer during lunch hours. Bring your current CDL permit, proof of residency, and $10 endorsement fee. No appointment necessary, but check mvd.newmexico.gov for any changes.
If you fail, you can retake the test the same day after a short wait. There's no limit on attempts, but each retry costs another $10. Use our practice test to avoid extra fees. The test is available in English and Spanish.
