Key Takeaways

  • Indiana law mandates seat belt use for all drivers and passengers over 16, enforceable under primary law.
  • Children must use age-appropriate restraints: rear-facing (birth–3), forward-facing harness (4–7), booster or seat belt (8–12).
  • Exemptions include medical conditions, farm trucks, USPS/commercial vehicles on frequent stops, parade participants, RV living areas, and ambulance treatment areas.
  • Indiana does not recognize the seat belt defense, so failure to buckle does not reduce personal injury claims.
  • Drivers are legally responsible for restraining passengers under 18 and may face penalties if minors are unbuckled.

Considering how effective seat belts have proven to be since their invention, there are still people who choose to drive without buckling up. Seat belts have saved more than 374,000 lives since 1975, according to the National Safety Council data. Indiana has clear laws on using seat belts while driving that every motorist should be aware of.

What Does Indiana Law Say About Seat Belts?  

All states in the U.S. follow either primary or secondary enforcement laws for seat belts. Indiana law requires all passenger vehicle occupants to wear seat belts, particularly in the front passenger seat and passenger seat areas. Under primary enforcement laws, a police officer can pull a driver over solely for not wearing a seat belt, which can impact their driving record. In states with secondary enforcement, an officer can only issue a ticket for not wearing a seat belt if another citable traffic infraction occurs. Failure to comply with seat belt laws may also affect a personal injury claim in case of an accident.

Indiana has a primary seat belt law, which means you can be stopped and ticketed solely for not being strapped in. As outlined in Indiana Code 9-19-10-2, all drivers and passengers over the age of 16 must wear seatbelts when the vehicle is in motion. This applies to both front seat and back-seat passengers​​​​.

Children and Seat Belt Laws

Each year, there is a devastating number of little ones who fall victim to fatal crashes. In 2021, motor vehicle accidents claimed the lives of 711 children under 13 across the country. Nearly 36% of these kids were found to be not wearing seat belts, suggesting many of these tragedies could have been avoided.

This is why state and federal organizations are constantly reviewing and updating Indiana seat belt law for child guidelines to help parents make sure their kids are correctly buckled up, reducing the risk of injury in a car accident.

Indiana takes the safety of young passengers very seriously. The state’s laws require that infants and small children who are not big enough for a car’s standard seat be properly restrained in a car seat that meets all federal safety standards.

You must select the right type of safety belt or car seat and position it correctly in your moving vehicle, considering your child’s age and body size. Once a child outgrows a car seat, transitioning to a booster seat ensures they remain secure. Without proper restraints, the forward motion of a crash can result in severe injuries, even with air bags. If a child is found unrestrained, the driver can be held responsible for the violation.

Birth to 12 months

Children under 1 year should always ride in a rear-facing car seat. This includes infant-only seats and convertible or all-in-one car seats with higher height and weight limits.

1 to 3 years

Keep children rear-facing as long as possible until they reach the top height or weight limit allowed by the car seat’s manufacturer. After outgrowing the rear-facing seat, they can move to a forward-facing car seat with a harness and tether.

4 to 7 years

Continue using a forward-facing seat with a harness and tether until the child reaches the top height or weight limit set by the manufacturer. After this, switch them to a booster seat, still in the back seat.

8 to 12 years

Children from 8 to 12 must use a child restraint or seat belt in all seating positions in all vehicles. They should use a booster seat until they are big enough to fit in a seat belt properly. The lap belt must lie comfortably across the upper thighs, not the stomach, and the shoulder belt should lie snugly across the shoulder and chest, not crossing the neck or face. Any child 12 and under must sit in the back seat if available.

Indiana Seat Belt Laws Exemptions

While Indiana seat belt laws require most drivers and passengers to wear seat belts, there are specific exemptions based on medical conditions and certain vehicle types.

Individuals—both adults and children—who have a documented medical condition preventing them from safely using a seat belt are exempt. To qualify, they must possess a doctor-issued medical certificate confirming the impracticality of using a restraint system due to physical or mental health limitations.

Other Seat Belt Exemptions in Indiana

Beyond medical exemptions, Indiana law provides seat belt exceptions for specific scenarios, including:

  • Commercial or USPS vehicles that make frequent stops for package or service deliveries.
  • Participants in a parade riding in a motor vehicle.
  • Passengers in the living quarters of a recreational vehicle (RV).
  • Farm trucks are actively used in agricultural operations.
  • Patients in the treatment area of an ambulance.

For a full list of seat belt exemptions, refer to Indiana Code 9-19-10-1.

Seat Belt Defense in Indiana: Can It Impact Your Car Accident Claim?

In some states, not wearing a seat belt can be used against car accident victims in insurance claims or lawsuits under the seat belt defense. This legal argument suggests that failing to wear a seat belt contributed to the severity of injuries, potentially reducing compensation.

However, Indiana law does not recognize the seat belt defense. This means that in an Indiana car accident case, the fact that a victim was not wearing a seat belt cannot be used as evidence of negligence or to diminish a personal injury claim.

That said, if a legal case involves vehicle safety defects or product liability litigation, seat belt usage may be considered as evidence. Consulting with an experienced car accident lawyer can provide further insight into how seat belt laws may affect your claim.
