📘 Study Tips & State Info
Visit your local DMV early in the day – the Kapolei office gets packed by 10 AM. Bring your current CDL and medical card. The test is computer-based and you'll get results right away.
Don't just memorize the handbook. Practice coupling diagrams and air brake troubleshooting. Use our test to find weak spots, then review those sections in the Hawaii CDL manual. Focus on island-specific rules like maximum trailer length on state highways.
If you fail, you can retake it the same day at some locations. But save the fee – pass on your first try with steady practice.
You can take the Doubles/Triples knowledge test at any Hawaii CDL testing site: Honolulu (Ala Moana), Hilo, Kahului, Lihue, and Kona. Most require an appointment. Walk-ins are limited. The test fee is $10 per attempt, payable by cash or card.
Bring your valid Hawaii CDL, social security card, and proof of residency. The test has 20 questions and you'll have 25 minutes. Score 80% or higher to pass. Once you pass, you can get the endorsement added at your next license renewal or upgrade.
For the skills test (if required), you'll need to provide a vehicle. Many training schools in Honolulu offer rental doubles. Check with HDOT for specific vehicle requirements – your trailer must have operational lights and brakes.
About the Hawaii Doubles and Triples Test
Hawaii's roads aren't like the mainland. You'll face tight turns on the H-1, steep grades on the Pali, and narrow bridges on Kauai. Doubles and triples require extra skill here. Our practice test focuses on those real-world conditions.
Tourism and agriculture drive Hawaii's economy. You might haul double trailers of pineapples from Wahiawa or deliver supplies to hotels along the Kona coast. Every maneuver matters when space is tight and traffic is heavy.
We cover the Hawaii CDL manual's Doubles/Triples section inside out. You'll learn coupling procedures, air brake checks, and how to handle crosswinds on the H-3 viaduct. Short lessons, clear questions, instant feedback.
Take this test free, no sign-up needed. Pass it, and you'll be ready for the real thing at any Hawaii DMV location.
