Helmet rules

- Required under age 16

- TCA § 55-52-105 requires every person under 16 to wear a properly fitted and fastened approved bicycle helmet whenever operating or riding as a passenger on a bicycle on any public road, sidewalk, or bike path.

Sidewalk riding
- Statewide rule
- Defers to local rules
- Notes
- Tennessee has no statewide statute on sidewalk cycling; municipalities regulate it under their general traffic-ordinance authority. Nashville prohibits bicycle riding on sidewalks in the central business district; Memphis and Knoxville restrict it in their downtown core but permit it elsewhere. Always check the municipal code before riding the sidewalk.

A bell does not replace yielding or signaling, but it can warn other path users; compare bike bells and horns.

- Tennessee's DUI statute (TCA § 55-10-401) applies only to a person who drives or is in physical control of an 'automobile, automobile truck, motorcycle, motor-driven cycle, self-propelled vehicle, or any other motor-driven vehicle.' Because a bicycle is human-powered, the DUI statute does not reach bicycle riders. An impaired cyclist may still be cited under public-intoxication statutes.

If alcohol or drugs may impair the rider, do not ride; arrange another way home and secure the parked bike with a lock suited to the theft risk.
