Topic overview

Safety belts and child restraints are not optional in Tennessee — they are the law, and it is a law officers can stop and ticket you for on its own. This section covers who must be buckled, how children of different ages and sizes must be restrained, and why belts matter so much in a crash. It is one of the most testable sections because the age and size rules are specific.

Every driver and all front-seat passengers must wear a safety belt whenever the vehicle is moving. Back-seat passengers under 17 must also be belted. For children, the rules go by age and size: rear-facing seats for the youngest, then forward-facing seats, then a booster seat for children four through eight who are shorter than four feet nine inches, and a regular belt once they fit it properly. The driver is responsible for properly restraining children up to age 16.

Belts work because they keep you inside the vehicle and spread crash forces across the strongest parts of your body — being thrown from a car is far more deadly than staying inside. Wear the lap belt low across your hips and the shoulder belt across your chest, never behind your back or under your arm. There are related rules too: children under six may not ride in the bed of a pickup, and leaving a young child alone in a car — where heat can turn dangerous fast — carries real penalties.

When does a child need a booster seat in Tennessee?

A child four through eight years old who is shorter than four feet nine inches must ride in a belt-positioning booster seat, using the seatbelt, and in the back seat if the vehicle has one. Younger children need forward-facing or rear-facing seats depending on age and weight.

Do back-seat passengers have to wear a seatbelt?

Back-seat passengers under 17 years old must wear a safety belt; the requirement no longer applies once they are 18 or older. If the driver holds a learner permit or intermediate license, back-seat passengers between four and 17 must be belted.

How should a pregnant woman wear a seatbelt?

Wear the lap belt below the abdomen and the shoulder belt above the belly. The belt should still be snug across the strongest parts of the body — never place the shoulder belt behind your back or under your arm.
