Motorcycle Helmet & Lane-Splitting Laws in Tennessee

Tennessee's motorcycle rules split into two separate questions: what you're required to wear, and how you're allowed to use a lane. Both carry criminal penalties, and both can shape how a crash claim gets valued if you're hurt riding here. Here's what actually applies in Tennessee in 2026, statute by statute.

Tennessee requires a helmet, full stop

Tennessee has a universal helmet law. Every motorcycle operator and every passenger, on a motorcycle, motorized bicycle, or motor-driven cycle, must wear a crash helmet that meets the federal safety standard in 49 C.F.R. § 571.218, the same benchmark DOT-certified helmets carry.¹ There's no exception for adult riders and no "if you've got insurance" carve-out. Age only changes which helmet qualifies, not whether one is required.

Riders 21 and older get a second option: a helmet that doesn't meet the full federal standard, as long as it carries a compliance label from the American Society for Testing and Materials (ASTM), the Consumer Product Safety Commission (CPSC), the Southern Impact Research Center (SIRC), or the Snell Foundation, and any ventilation holes in the shell are no more than an inch and a half across.¹ Below 21, only the federally compliant helmet counts.

A few narrow situations don't require a helmet at all: riding in an enclosed cab or a fully enclosed autocycle, riding a golf cart, moving in a parade at 30 mph or slower if you're 18 or older, or riding in a funeral procession, a police-escorted memorial ride, or a body escort detail at 30 mph or slower if you're 21 or older.¹ Outside those situations, the helmet requirement applies every time you're on the bike, on any public road in the state.

Tennessee also requires eye protection. Every motorcycle or motor scooter on a Tennessee road needs a windshield, or the rider and any passenger need to wear goggles, a face shield, or glasses with impact-resistant lenses. That requirement was last amended effective July 1, 2024.² Separately, every motorcycle has to carry a rearview mirror and footrests for both rider and passenger.³

The fine is small, but lawmakers keep failing to change that

Riding without a required helmet is a Class C misdemeanor, the same classification that covers most Title 55 equipment and rules-of-the-road violations. That means up to 30 days in jail, a fine of up to $50, or both, and a court can also order a driver improvement course with a fee between $50 and $175.⁴ In practice, most citations resolve as a fine.

The law has been a repeated target in the General Assembly. A 2021-2022 bill would have let riders 26 and older skip the helmet if they carried health insurance outside TennCare; it died in committee in April 2022.⁵ A 2023 bill proposed a four-year pilot letting insured riders 21 and older opt out; it failed in a House transportation subcommittee that March.⁶ Neither change made it into the code, and the helmet mandate stands exactly as written above.

Lane splitting is illegal; riding two abreast isn't

Tennessee law addresses motorcycles and lane position directly. A motorcycle is entitled to the full width of a lane, and no other vehicle can be driven in a way that deprives it of that space.⁷ But the same statute draws firm lines around what a motorcyclist can do with that lane. No one may operate a motorcycle between lanes of traffic or between rows of stopped or moving vehicles, which is what most people mean by lane splitting. A motorcyclist also can't overtake and pass another vehicle within the same lane that vehicle occupies, and motorcycles can't ride more than two abreast in a single lane.⁷ Riding two abreast, one motorcycle beside another in the same lane, is the one exception written into the statute; everything else about squeezing into gaps between vehicles is off-limits. Police officers on official duty aren't bound by these restrictions.⁷

Lane splitting is treated as a moving violation, prosecuted under the same Class C misdemeanor penalty that covers most rules-of-the-road offenses in chapters 8 and 9 of Title 55.⁴

What this means if you're hurt in a crash

Tennessee is a modified comparative fault state: under McIntyre v. Balentine, you can recover damages as long as you're found less than 50% responsible, but your award drops by your own share of fault.⁸ A citation for lane splitting, or a documented helmet violation, becomes part of that fault conversation once a claim is contested, on top of whatever the other driver did wrong.

The injury clock is short. Tennessee gives you one year from the crash date to file an ordinary personal injury claim, or two years if the case is tied to a criminal prosecution of the at-fault driver.⁹ A separate three-year window applies if you're only pursuing damage to the motorcycle itself.¹⁰

Motorcycle crashes tend to produce catastrophic injuries, and Tennessee's damage-cap rules matter more here than in an average fender-bender. There's no cap on economic losses like medical bills or lost wages. Noneconomic damages are generally capped at $750,000, rising to $1 million for a catastrophic injury or death, though that cap disappears entirely if the at-fault driver was under the influence.¹¹ Given how often impaired drivers show up in motorcycle fatalities, that exception can matter more than the base cap number.

Minimum liability coverage in Tennessee is $25,000 per person and $50,000 per accident for bodily injury.¹² That ceiling clears an average car crash; it often doesn't cover a motorcyclist's hospital bill. Insurers have to offer uninsured/underinsured motorist coverage matching those same limits, but a policyholder can reject it or pick something lower in writing, so check your own declarations page rather than assume you're covered.¹³

If the bike itself was declared a total loss, our Tennessee diminished value guide covers what you can still recover for it.
