Hawaii Permit Test Study Guide (2026)

Cover every topic on the Hawaii DMV permit test, ranked by how often they show up on the real exam.

The Hawaii Driver Manual is your main study tool. It covers traffic laws, road signs, DUI rules, sharing the road, and safe driving in Hawaii. The state writes the test from this manual. The manual is in English and 13 other languages, including Hawaiian, Tagalog, and Ilocano.

Hawaii Speed Limits

Speed limits are one of the most-tested topics on the HI permit exam, and the questions usually test Hawaii's statutory default limits -- what the speed is when no sign is posted. Hawaii's maximum and minimum speed limits are established by county ordinance or by official signs, not one flat statewide number (H.R.S. Section 291C-102); residential districts are commonly 25 mph and school zones are commonly 25 mph, both set by the counties. Always obey the basic-speed law: never drive faster than is safe for current conditions.

Alcohol & BAC Limits

Expect at least one alcohol question on the Hawaii permit test. Memorize the three BAC thresholds: 0.08% is the legal limit for drivers age 21 and older, 0.04% is the limit for anyone driving with a commercial driver license (CDL), and Hawaii's threshold for drivers under 21 is 0.02% (H.R.S. Section 291E-64) -- defined as a "measurable amount," 0.02% up to (but under) 0.08%. A first violation requires the driver (and their parent or guardian, if under 18) to attend an alcohol abuse education program. A BAC of 0.08% or higher brings full adult OVUII charges instead.

Right-of-Way Rules

Right-of-way is the single most-missed topic across every state's permit test. The rules are simple once you memorize them. At a 4-way stop, the first vehicle to fully stop goes first; if two arrive together, the driver on the right has the right of way. At an uncontrolled intersection, yield to any vehicle already in the intersection and to the driver on your right. At roundabouts, yield to traffic already circulating and enter only when there is a safe gap. Always yield to pedestrians in any crosswalk, marked or unmarked, and to emergency vehicles with lights and sirens — pull right and stop. When turning left across oncoming traffic, you must yield to oncoming vehicles. Yield does not give you the right of way; it requires you to give it up.

Following Distance & Safety

Hawaii's driving guidance recommends a minimum 3-second following distance: pick a fixed point on the road, wait for the vehicle ahead of you to pass it, then count one-thousand-one, one-thousand-two, one-thousand-three. Increase that to 4 or 5 seconds in rain.

Road Sign Colors & Shapes

Road signs on the HI permit test follow the federal Manual on Uniform Traffic Control Devices, so shapes and colors are consistent across the country. Memorize the shapes first: octagon always means stop, downward triangle means yield, diamond means warning, pentagon marks a school zone, round warns of a railroad crossing, and horizontal rectangle is a guide sign. Then learn the colors: red is stop or prohibition, yellow is general warning, orange is construction, green is directions and exits, blue is driver services, brown is recreation, and fluorescent yellow-green is for schools and pedestrians. Practice identifying signs by shape and color alone — see the full visual cheat sheet on our Hawaii road-signs page.

Key Hawaii Numbers to Memorize

If you only remember a handful of facts going into the test, make it these. Every one of them maps to questions that have appeared on the real HI exam.

Parking Rules

Parking questions on the Hawaii permit test cover two patterns everywhere. For parallel parking, your wheels should be no more than 12 inches from the curb. For hill parking, the kerb rule decides which way your front wheels point: facing downhill (with or without a curb), turn the wheels toward the curb; facing uphill with a curb, turn the wheels away from the curb so they rest against it; facing uphill with no curb, turn the wheels toward the edge of the road. Always set the parking brake and leave the car in park (or in low gear with a manual).

Hawaii's no-parking zones (H.R.S. Chapter 291C) you must memorize: within 10 feet of a fire hydrant, within 20 feet of a crosswalk or intersection (this crosswalk distance was only added statewide by Act 171, effective January 1), within 30 feet on the approach to a flashing beacon or stop sign, and within 50 feet of the nearest rail at a railroad crossing.

GDL Restrictions (HI)

Hawaii's instruction permit: supervised at all times by someone 21 or older licensed for the same vehicle type -- between 11 p.m. and 5 a.m., that supervisor must specifically be your parent or guardian. Log 50 hours of supervised driving, including 10 at night. The provisional license's night curfew is also 11 p.m. to 5 a.m., with an exception for driving directly to or from your job. Passenger restrictions: no more than one passenger under 18 outside your household unless your licensed parent or guardian is riding along. Expect 1-3 GDL questions on the HI exam.

DUI & Drug Laws

DUI questions go beyond the BAC limits in Section 2. Three concepts you must know: implied consent means refusing a chemical test triggers automatic license suspension on top of any DUI charge. Prescription and over-the-counter drugs can also impair driving — antihistamines, sleep aids, painkillers, and some cold medicines list "do not operate heavy machinery" warnings, and driving impaired by them is a DUI even if you have a valid prescription. Marijuana — even where state-legal — is treated like alcohol for driving: any detectable impairment can result in a DUI, and edibles can take 1–3 hours to peak. The only safe BAC and the only safe THC level for driving is zero. There is no quick way to sober up; only time will lower your BAC.
