Tennessee Motorcycle Helmet Laws Explained

Tennessee's helmet law is universal — every rider and passenger must wear an approved helmet, with no age-based exemption, unlike states such as Arizona where only riders under 18 are required to.

The specific federal standard, FMVSS 218, is what the helmet must meet — a detail worth knowing beyond just 'DOT-approved,' since it names the actual regulation.

Because legislation can be introduced or amended, confirm the current status of Tennessee's helmet law on the official TDOSHS website before you ride.

Under TCA 55-8-182, a motorcycle is entitled to full use of a lane, but may not pass between two lines of vehicles traveling in the same direction — lane splitting is illegal in Tennessee.

This rule is separate from the helmet law but frequently appears alongside it on the written test, since both fall under protective/defensive riding practices.

Because Tennessee's law is universal rather than conditional, test questions tend to focus on the specific certification standard (FMVSS 218) rather than an age threshold.

The written test also covers other protective gear and Tennessee-specific riding techniques, like the T-CLOCS inspection and SIPDE strategy, alongside the helmet requirement.
