Did you know the Arizona seat belt law can leave a violation on your driving record? Whether you are navigating the I-10 through Phoenix or cruising Route 66 in Flagstaff, buckling up is both a legal requirement and a life-saving habit.
Here are six key things every Arizona driver needs to know in 2026.
1. Front Seat Occupants Must Always Buckle Up
Under Arizona Revised Statute Section 28-909, each front seat occupant of a motor vehicle designed to carry ten or fewer passengers, manufactured for model year 1972 and later, must have their lap and shoulder belt properly adjusted and fastened while the vehicle is in motion.
2. It Is a Secondary Enforcement Law for Adults
Arizona is a secondary enforcement state when it comes to seat belts. That means a police officer cannot pull you over just for not wearing a seat belt. A citation is only issued after a stop for a separate primary traffic violation.
3. The Adult Fine Is $10 Per Violation
Failing to wear a seat belt is considered a civil traffic violation in Arizona. The statutory penalty is a $10 fine per violation. However, no points are added to your license for seat belt violations, but the infraction will still be recorded on your driving record.
4. Children Under 8 Have Strict Car Seat Requirements
Arizona’s car seat law applies to all children under eight years old. All children under five years old must ride in a child restraint regardless of their height or weight. Children younger than 8 and shorter than 4 feet 9 inches must be in a child restraint system, which includes a booster seat if they have outgrown a forward-facing car seat.
5. Child Safety Violations Carry a $175 Fine
If a child under the age of 8 is not using the appropriate car seat or booster seat, the driver may face fines of up to $175. In some cases, the fine may be waived if you provide sufficient proof that you have subsequently equipped your vehicle with a compliant child restraint system.
6. Not Wearing a Belt Can Hurt Your Injury Claim
Arizona is one of 16 states where damages may be reduced in a lawsuit due to the non-use of a seat belt. If you are hurt in a crash and were not buckled up, the at-fault driver’s insurer can argue your injuries were made worse by your own actions. This could significantly reduce any compensation you receive.
Final Takeaway for Arizona Drivers
The Arizona seat belt law is straightforward but easy to overlook in daily driving. A $10 ticket today can turn into a much larger financial loss after a crash. Always wear your seat belt, ensure every child is properly restrained, and speak with a licensed Arizona attorney if you have questions following an accident.
