Did you know the Hawaii seat belt law requires every person, in every seat, to buckle up? Whether you are driving H-1 on Oahu, the Hana Highway on Maui, or the Queen Ka’ahumanu Highway on the Big Island, compliance is required every time your vehicle is in motion.
Here are six key things every Hawaii driver needs to know in 2026.
1. Every Occupant in Every Seat Must Wear a Seat Belt
Under Hawaii Revised Statutes Section 291-11.6, no person shall operate a motor vehicle upon any public highway unless the person is restrained by a seat belt assembly and all passengers in the front or back seat of the motor vehicle are also restrained by a seat belt assembly. Hawaii’s universal seat belt law is one of the most comprehensive in the nation.
2. Hawaii Is a Primary Enforcement State
Hawaii’s universal seat belt law ensures everyone, in both the front and back seats, stays protected by buckling up every trip, every time. Law enforcement officers across Oahu, Maui, Kauai, and the Big Island can stop a vehicle solely for an observed seat belt violation, without needing any other traffic infraction.
3. The Fine Is $100 or More Per Violation
Violations can result in fines of $100 or more, mandatory driver’s education classes, and additional surcharges. With court costs added, total fines can exceed $100 per unrestrained occupant. Every unbuckled passenger in the vehicle can result in a separate citation.
4. Children Under 10 Must Use a Child Restraint System
Hawaii’s child passenger safety law requires children from birth through age 10 to ride in a properly fitted child safety seat or booster seat. Children under 2 years of age must be properly restrained in a rear-facing car seat with a harness. Children 2 years or older but less than 4 years old must be properly restrained in a rear-facing or forward-facing car seat with a harness.
Children 4 years of age or older but less than 10 must be properly restrained in a child passenger restraint system with a harness or booster seat that meets federal motor vehicle safety standards. A child ages 7 through 9 may use a lap and shoulder seat belt assembly instead of a booster seat if the child is over 4 feet 9 inches in height.
5. Child Restraint Violations Carry Steeper Penalties
For a child restraint violation, the first offense carries a fine of $100. Subsequent offenses carry a $250 fine, and the court may also order 4 to 8 hours of community service. No points are added to your license. Violators will be required by the court to attend a child passenger safety class approved by the Hawaii State Judiciary.
6. Several Exemptions Apply Under Hawaii Law
Exemptions from Hawaii’s seat belt requirement include a person in a motor vehicle not required to be equipped with a seat belt assembly under federal standards, a person whose number exceeds the seat belt assemblies available, provided all other belts are in use, a person with a condition that prevents appropriate restraint, duly certified by a physician or advanced practice registered nurse, and a person operating a taxicab. Emergency and mass transit vehicles are also exempt.
Final Takeaway for Hawaii Drivers
The Hawaii seat belt law is among the strongest in the country, covering every seat, every passenger, and every child up to age 10. Always buckle up on every island road, ensure keiki are in the correct restraint for their age and size, and speak with a licensed Hawaii attorney if you have legal questions following an accident.
