Hawaii Driving Laws 2026: Speed Limits, DUI BAC and Road Rules for the Hawaii Permit Test

Does Hawaii have one statewide default speed limit when no sign is posted on a city street? No. Hawaii speed limits are established by county ordinance or official state signs, and the basic speed rule still requires a reasonable and prudent speed for conditions. The permit knowledge test is 30 questions. Hawaii OVUII law uses 0.08% as the per se adult alcohol threshold, while drivers under 21 may not operate with a measurable amount of alcohol. Vehicle lights are required from 30 minutes after sunset to 30 minutes before sunrise. Hawaiis mobile electronic device law prohibits holding a mobile electronic device while operating a motor vehicle, including while temporarily stopped in traffic or at a red light.

1. Speed Limits in Hawaii

Does Hawaii have a statewide default speed limit when no sign is posted? Hawaii law does not use one single statewide default table for city streets, rural roads, school zones, and alleys. Maximum and minimum speed limits may be established by county ordinance or by official signs placed by the state Director of Transportation, and every driver remains subject to the basic rule against driving faster than is reasonable and prudent for conditions.

Key test point: Do not memorize a generic 35 mph Hawaii city-street default. For the Hawaii permit test, know that posted or locally established limits control, and the basic speed rule can require a lower speed whenever conditions make the posted maximum unsafe.

2. Right-of-Way: Who Goes First

Hawaiis knowledge test hits right-of-way consistently, pedestrian yielding and intersection priority rules are tested every time. In a state where tourist pedestrians outnumber locals on some Waikiki blocks, yielding correctly is not just a test question; it is a daily reality.

4-way stop (all arrive at once)

Driver to the right

4-way stop (one arrives first)

Driver who arrived first

Roundabout / traffic circle

Vehicles already inside the circle

Emergency vehicles (lights/siren)

Emergency vehicle, pull to the right and stop

Pedestrians in crosswalk

Drivers must stop as required for pedestrians crossing within a crosswalk; pedestrians must not suddenly enter the path of a vehicle that is too close to stop safely.

T-intersection (no signs)

Through road traffic; drivers on the dead-end must yield

Yield sign

Cross traffic and pedestrians always

Merging onto a highway

Traffic already on the highway

3. Turns & Signal Laws

Hawaii requires a turn signal for at least 100 feet before every turn or lane change, and warns that the signal alone does not give you the right to make the move. You must also confirm it is safe. Right turns on red are generally permitted after a full stop unless a sign prohibits it:

Right turn on red

Permitted after a full stop unless a sign prohibits it. Yield to pedestrians and cross traffic.

No right turn on red

When posted, you must wait for a green light before turning right.

Left turn on red

Only allowed from a one-way street onto another one-way street, after a full stop.

Left turn from two-way street

Start from the left lane; end in the left lane of the cross street.

Right turn

Stay as close to the right curb as possible; end in the right lane.

U-turns

Do not make a U-turn on a curve or near the crest of a grade where your vehicle cannot be seen by approaching drivers from either direction within at least 500 feet. Also obey posted no-U-turn signs.

4. Lane Rules & Line Markings

On Hawaiis H-1, H-2, and H-3 freeways and its network of two-lane highways across four islands, lane rules matter. One Hawaii-specific detail: red lane reflectors mean you are traveling the wrong way in a traffic lane, a real hazard on some of Oahus reversible lanes. Heres the full breakdown:

Center turn lane (CTSL)

Used only for left-turn maneuvers by traffic in either direction; never use the center lane for ordinary through travel or passing.

Solid white line

Do not cross; marks the edge of the road or a lane that should not be changed.

Solid yellow line (your side)

No passing allowed.

Broken yellow line

Passing allowed when safe.

Solid + Broken yellow centerline

Passing allowed only on the broken-line side.

5. Passing Another Vehicle

On Hawaiis narrow two-lane roads, the Hana Highway on Maui, Chain of Craters Road on the Big Island, Kamehameha Highway on Oahus North Shore, passing is frequently impossible and always demands caution. Heres what Hawaii law requires:

• Only pass on the left, using the oncoming lane, when it is safe and legal.
• Passing a bicyclist: When overtaking a bicyclist traveling in the same direction, allow at least 3 feet between your vehicle, including mirrors or other protuberances, and the bicyclist.
• Do not pass within 100 feet of an intersection, railroad crossing, bridge, or curve where your view is limited. Look for the No Passing Zone pennant sign.
• The vehicle being passed must not speed up while you are overtaking.
• Return to your lane before coming within 200 feet of oncoming traffic.
• Do not pass a stopped school bus when Hawaii law requires you to stop for its flashing red signals.
• Passing on the right is permitted when the vehicle ahead is turning left, on a roadway with marked lanes wide enough for two or more lines of moving vehicles in each direction, or on a one-way roadway of sufficient width. Do not leave the roadway to pass except where specifically allowed by law.

6. Following Distance

Hawaiis sudden tropical downpours, sun glare off the Pacific, and slow-moving tourist traffic all affect how much following distance you need. Hawaii law requires drivers to follow at a distance that is reasonable and prudent, considering vehicle speed, traffic, and highway conditions.

7. School Buses & Emergency Vehicles

Hawaiis school bus stop rules and the requirement to yield to emergency vehicles are directly tested on the knowledge exam. The school bus rule depends on which lane the bus occupies, which lanes are adjacent, and whether opposing traffic is on a separate roadway of a divided highway.

School Buses

• When a school bus is stopped with flashing red signals, drivers covered by Hawaiis school bus stop law must stop at least 20 feet from the bus and must not proceed until the bus resumes motion and the flashing signals are off.
• On a highway or road in a residential area, the stop rule applies to the lane occupied by the bus and all lanes adjacent to that lane, regardless of the direction of travel.
• Drivers traveling in the opposite direction on a divided highway are not required to stop when the school bus and their vehicle are on different roadways. Traffic on the same roadway remains subject to the applicable stop rule.
• A divided highway is one in which the opposing roadways are separated as provided by Hawaii law; do not assume that ordinary lane markings alone create the divided-highway exception.
• A school-bus stop-law violation may result in a fine of up to $500 or community service, or both; a qualifying violation on a state highway may carry a fine of up to $1,000 or community service, or both.
• Railroad crossings: A school bus carrying school children is among the vehicles required to stop before railroad tracks, generally within 15–50 feet of the nearest rail unless an applicable statutory exception directs otherwise.

Emergency Vehicles

• When you see or hear an emergency vehicle (police, fire, ambulance) with lights or siren: pull to the right edge of the road and stop. Do not block intersections.
• Move Over Law (Hawaii): When approaching a stopped emergency vehicle displaying flashing emergency lights, slow to a reasonable and prudent speed and, when necessary and safe, move into an adjacent lane or, if possible, two lanes over to leave one lane between your vehicle and the stopped emergency vehicle. For this law, emergency vehicles include specified police, fire, emergency-response and freeway-service vehicles, and tow trucks.

8. Driving Under the Influence in Hawaii

Hawaii calls the offense operating a vehicle under the influence of an intoxicant (OVUII). A driver can violate the law by being impaired by alcohol or drugs, or by operating with an alcohol concentration of 0.08% or more. Drivers under 21 may not operate a vehicle with a measurable amount of alcohol. Administrative license revocation is separate from the criminal OVUII case.

9. Seat Belts & Child Seats

Hawaii law requires the driver and all passengers in the front or back seat to be properly restrained by a seat belt or, for children under age 10, by the child passenger restraint required by law. A crash at just 12 mph can be fatal without a belt, and at 30 mph, occupants are thrown forward with deadly force.

10. Where You Cannot Park

How close can you park to a crosswalk or intersection in Hawaii? Effective January 1, 2026, Hawaii prohibits parking a vehicle abutting the curb or edge of the vehicle travel way within 20 feet of a crosswalk or intersection, regardless of signs or curb markings, subject to statutory exceptions. The Hawaii Drivers Manual also requires a parallel-parked vehicle to be no more than 12 inches from the curb unless it is completely within a marked parking stall.

• Within 20 feet of a crosswalk or intersection where the statewide 2026 rule applies
• More than 12 inches from the curb when parallel parked, unless completely within a marked parking stall
• On a sidewalk or sidewalk area
• In front of or too close to a driveway when your vehicle would interfere with use of the driveway
• So close to a fire hydrant that your vehicle could interfere with access to it
• Where official signs, curb markings, or other lawful traffic controls prohibit parking
• On a bridge or other elevated structure, or in a tunnel
• On the roadway side of another vehicle stopped or parked at the edge of the road (double parking)
• In a passenger or freight loading zone except as permitted
• Headed downhill: turn wheels toward the curb. Headed uphill with a curb: turn wheels away from curb. Uphill without a curb: turn wheels toward the shoulder.

11. Driving in Bad Weather

Hawaiis weather hazards are unlike any other state. Volcanic smog ("vog") from Kilauea reduces visibility on the Big Island. Flash floods can sweep vehicles off roads in minutes on Oahus windward side. Tropical downpours arrive without warning. And fog can appear suddenly on Haleakala, Saddle Road, and Pali Highway. Heres how the handbook says to handle each:

• In heavy rain, turn on low beam headlights so others can see you. If visibility drops so you cannot see clearly, pull completely off the road and stop.
• In heavy fog, use low beams, high beams reflect off fog and reduce visibility.
• If you start to hydroplane, ease off the gas gently. Do not brake hard or turn sharply.
• In icy conditions, brake gently well in advance. Start slowing earlier than normal. Leave extra following distance.
• If your car goes into a skid, steer in the direction you want the front of the car to go. Do not overcorrect.
• Never use cruise control on wet, icy, or slippery roads.

12. Traffic Abstracts & License Suspensions

Does Hawaii have a drivers license point system? No. Hawaiis former demerit-point system was repealed in 1997. Hawaii currently tracks moving violations through driver records and traffic abstracts, while suspension or revocation can still be imposed under the statutes that apply to specific offenses.

Key test point: If you are searching how many points a speeding ticket adds in Hawaii, the answer is that Hawaii does not currently assign demerit points. The fine, court consequence, or license action depends on the specific violation and the drivers record.

13. Headlight Rules

Hawaiis headlight rules are straightforward: keep low beams on except when high beams are needed to see ahead, and dim immediately when another vehicle approaches or when following. On unlit rural roads on Maui, the Big Island, and Kauai, proper headlight use is critical.

Key test point: Hawaii law requires headlights from 30 minutes after sunset until 30 minutes before sunrise. In fog, always switch to low beams, high beams reflect off moisture and reduce your vision. Red lane reflectors mean you are going the wrong way; blue or white reflectors confirm correct direction.

14. Night Driving

Hawaiis rural roads, especially on Maui, Kauai, and the Big Island, are unlit and can be pitch black at night. The handbook is direct: reduce your speed so you can stop within the distance you can see ahead. Free-range animals, including horses and cattle on parts of the Big Island and Molokai, cross roads without warning after dark.

15. Cell Phones & Distracted Driving

Hawaiis handbook devotes significant attention to distractions, noting that even hands-free phone conversations take attention away from driving. The state prohibits handheld device use while driving, and the handbook specifically recommends pulling over to the side of the road in a safe place before taking any call.

Key test point: Hawaii treats a vehicle temporarily stopped in traffic, at a traffic light, or at a stop sign as still being operated for the mobile-device law. Drivers under 18 may not use a hands-free mobile electronic device except for a 911 emergency communication.

16. Railroad Crossings

Even though Hawaii has relatively few railroad crossings, the Hawaii Drivers Manual still covers railroad-crossing rules. Know when an ordinary driver must stop, the minimum stop distance, and which vehicles have additional stopping duties.

Key test point: Never drive around or under a lowered crossing gate, it is illegal and extremely dangerous. Wait until gates are fully raised and all tracks are clear.

17. How to Drive a Roundabout

Roundabouts appear at intersections across Hawaiis islands, particularly on Oahus suburban corridors and on resort areas of Maui. The Hawaii knowledge test covers them directly. The rule no one should miss: vehicles entering the roundabout must yield to vehicles already circulating inside, every time.

Key test point: The most common wrong answer on roundabout questions is thinking you have right-of-way when entering. You never do, yield to traffic already inside.
