Hawaiʻi’s universal seat belt law requires that all front and back seat motor vehicle occupants buckle up. Adults and children must use their seat belts and child restraints at all times. The cost of a ticket for not buckling up is currently $102. The child passenger restraint law requires children under 4 years of age to ride in a child safety seat, and children between the ages of 4 and 8 years to ride in either a child safety seat or a booster seat. Violators of this law are required to attend a four-hour class and may be assessed a fine between $100 and $500 depending upon the number of offenses.
Handheld Electronic Devices
Using mobile electronic devices while operating a motor vehicle is illegal in Hawaiʻi. This includes cell phones, mp3 players, personal digital assistants, and navigation devices. The law also prohibits drivers from using hand-held mobile electronic devices when stopped at a red light or stop sign. Additionally, no person under the age of 18 may use a hands-free mobile electronic device while operating a motor vehicle. The fine starts at $257. Violations in school zones or construction areas are subject to a higher amount. The exception is for 9-1-1 emergency calls.
