Traffic Safety Laws in Tennessee
Child Car Seat Laws
- Children younger than 1 year old or weighing 20 lbs. or less must be properly secured in an approved rear-facing child passenger restraint system.
- Children between 1 to 3 years old weighing more than 20 lbs. must be properly secured in an approved forward-facing or rear facing child passenger restraint system.
- Children 4 to 8 years old and less than 4 ft 9 in tall must be properly secured in an approved belt-positioning booster seat system.
Children exceeding these limits must follow the seat belt rules listed below.
If you're in the market for one, you can shop online for a car seat at any time. When ordering, be sure the seat matches your child's height, weight and age.
NOTE: The above are the minimum state requirements. Visit the NHSTA website for size recommendations that can be safer for your child.
Any adult, and any child exceeding the child safety seat limits, must be properly secured by a seat belt when riding in the front seat of a vehicle. Both shoulder and lap belts must be used if the vehicle is equipped with them.
Drivers are responsible for seeing that the safety belt and child safety seat rules are followed in their vehicle. Drivers can be nailed with a ticket, fine, and points on their license for failing to ensure compliance within their vehicle.
However, licensed passengers 16 years old or older are responsible for their own conduct, and may receive a ticket for disobeying the rule.
Law enforcement officials may stop a vehicle solely for a safety belt or child restraint seat infraction.
