About the Hawaii General Knowledge Test

- ✓Basic vehicle control — steering, accelerating, braking on roads like the Likelike Highway where tight curves and steep grades test your skill
- ✓Shifting and gear management — you'll need to know proper RPM ranges for climbing and descending the Pali, where engine braking saves your service brakes

📘 Study Tips & State Info
Hawaii DMV examiners emphasize the pre-trip inspection. They want to see you walk around your vehicle in the right order, checking everything from tires to lights. Don't skip the air brake check — that's where most people lose points. They also ask questions about the 'seven-step inspection method' from the Hawaii CDL manual. Memorize that sequence.
For the written test, focus on the sections about driving in rain and reduced visibility. Hawaii gets more annual rainfall than any other state, and the test questions reflect that. Know your stopping distances on wet roads and how to handle hydroplaning. Also study the cargo securement rules — Hawaii's inter-island shipping industry moves everything from vehicles to perishables, and the DMW expects you to know how to tie it down.
One thing Hawaii examiners check: your knowledge of emergency procedures. They'll ask what to do if your brakes fail on a long downgrade. The answer is always 'use engine braking and escape ramps' — but Hawaii has very few escape ramps, so you need to know how to manage your speed before you start descending. I tell my students to picture the Pali Highway going down into Honolulu. That mental image helps you remember the correct answer.
Hawaii DMV offices that handle CDL testing are located on Oahu (Honolulu, Kaneohe, Waipahu), Hawaii Island (Hilo, Kona), Maui (Kahului), and Kauai (Lihue). You need to make an appointment — walk-ins aren't accepted for CDL tests. Call ahead or book online. Fees vary by island but expect about $40 for the written test and $50 for the skills test.
You must bring your valid driver's license, Social Security card, proof of Hawaii residency, and a current Medical Examiner's Certificate (DOT physical). If you don't have the medical card, you can't take any CDL test. The DMV also requires a completed CDL application form, which you can download from the Hawaii Department of Transportation website.
One thing that trips up out-of-state applicants: Hawaii doesn't issue CDLs to non-residents. You need to establish residency first. And if you already have a CDL from another state, you must surrender it when you apply for a Hawaii CDL. The written test is the same for everyone — no exceptions.
About the Hawaii General Knowledge Test
The General Knowledge test is the foundation for every Hawaii CDL — Class A, B, or C. You pass this first, then you can add endorsements. The test covers vehicle inspection, basic control, shifting, backing, and how to handle the unique conditions you'll face on Hawaii's roads.
Hawaii isn't like the mainland. You've got narrow two-lane highways on the windward side of Oahu, sudden rain showers that turn the H-3 into a skating rink, and vog from Kilauea that cuts visibility on the Big Island. The test includes questions about driving in these conditions because your examiner expects you to know them.
You'll also get questions about cargo securement — critical when you're hauling supplies between islands or delivering to resorts. And don't forget the military convoys sharing the road near Schofield Barracks. The General Knowledge test covers all of it.
You need 40 out of 50 correct to pass. That's 80%. Most people take about 60 minutes. Our practice test mirrors the real thing so you know exactly what to expect at the Hawaii DMV.
