Hawaii DMV Test — Key Facts
Knowing the specific numbers and rules before your Hawaii written knowledge test gives you a real advantage. Here are the key facts for this test:
- Hawaii DMV test: 30 questions, 80% required to pass (24 correct minimum)
- Hawaii BAC limit: 0.08% for drivers 21 and older
- Four-way stop: First to arrive goes first; simultaneous arrival — yield to vehicle on your right
- Solid yellow on your side: No passing from your direction — a legal prohibition
- Red X lane signal: Lane is closed — you must not drive in this lane
- Hawaii's roads: Narrow bridges, winding coastal routes, and frequent tropical rain require extra attention to fundamentals
How to Use This Test Effectively
Getting the most out of your Hawaii DMV practice time takes more than clicking through questions. Use these strategies:
- Hawaii's four-way stop rule has two parts. If vehicles arrive at different times, the first to arrive goes first. If two vehicles arrive at the same time, the vehicle on the right has the right-of-way. Both rules are tested on the Hawaii exam.
- The red X lane signal is an absolute prohibition. When a red X appears over your lane on an overhead lane control signal, you must not drive in that lane. Move to a lane with a green arrow as soon as it is safely possible.
- Hawaii's island roads demand good fundamentals. The Hana Highway on Maui, Waipio Valley Road on the Big Island, and Kauai's coastal roads feature narrow lanes, blind curves, and frequent rain. Solid knowledge of curve approach and passing rules is essential.
- Solid yellow on your side means no passing — full stop. A solid yellow line on your side of the center is a legal prohibition. You may not cross it to pass, regardless of how clear the road ahead looks.
- Headlights are required in Hawaii during rain. Hawaii's frequent tropical showers — especially on the windward sides of the islands — require headlights to be on whenever precipitation reduces visibility.
Frequently Asked Questions
How many questions are on the Hawaii DMV written test?
30 questions. You must answer at least 24 correctly (80%) to pass the Hawaii written knowledge test.
What is Hawaii's legal BAC limit for drivers 21 and older?
0.08%. Drivers 21 and older are considered legally impaired at a blood alcohol content of 0.08% or higher in Hawaii.
What should I do at a four-way stop in Hawaii?
If you arrive before other vehicles, proceed when safe. If two or more vehicles arrive at the same time, the vehicle on the right has the right-of-way. If facing each other going straight, both may proceed; a turning vehicle must yield.

When are U-turns legal in Hawaii?
A U-turn is legal only when it can be completed safely without interfering with other traffic, is not prohibited by a sign, and you have sufficient visibility in both directions. U-turns are generally prohibited in intersections with traffic signals.
