TRAFFIC RULES IN TENNESSEE

Heading to the Cracker Barrel 400 is all part of the adventure, but it’s worth brushing up on Tennessee’s driving laws before hitting the road. Most rules match those across the United States, but some are enforced particularly strictly in the Volunteer State – especially around major events like race weekend.

Traffic flow

As in the rest of the U.S., traffic drives on the right-hand side. If you’re visiting from a country that drives on the left, take extra care when entering intersections, exiting parking lots, or making U-turns near the Speedway.

Speed limits

Speed limits depend on the type of road. In residential areas, the limit is usually 25 mph. Rural highways are typically 55–65 mph, and interstates may reach 70 mph. Always keep an eye on posted signs – limits can change quickly near ramps or junctions. Tennessee Highway Patrol officers frequently monitor traffic with radar, and fines for speeding, especially 20 mph or more over the limit, can be severe.

Intersections & traffic lights

Traffic lights are strictly enforced, with cameras at several busy crossings. Right turns on red are allowed after a full stop unless a sign prohibits them. Always yield to pedestrians, and avoid accelerating through a yellow light if you can stop safely.

Alcohol & driving

Tennessee enforces strict DUI laws. The legal blood alcohol concentration (BAC) limit is 0.08% for drivers aged 21 and over, and just 0.02% for those under 21. During NASCAR weekends, sobriety checkpoints are often set up near major roads leading to and from the Speedway. If you plan to drink, arrange a designated driver, rideshare, or taxi in advance.

Seat belt laws

Everyone in the front seats must wear a seat belt, and police can stop you solely for not doing so. Back-seat passengers under 18 must also buckle up. The safest rule is simple – make sure everyone in the car is strapped in before leaving your parking spot.

Pedestrians & right of way

Drivers must yield to pedestrians at marked crosswalks and intersections without signals. At four-way stops, the first vehicle to arrive has the right of way. If two arrive at the same time, the car on the right goes first. Around the Speedway, expect large crowds on foot, so drive slowly and stay alert.

If you’re pulled over

If an officer signals you to stop, pull over safely to the right. At night, stop in a well-lit area if possible. Keep your hands visible on the steering wheel, follow the officer’s instructions, and remain calm and respectful throughout the interaction.
