Penalty

Mississippi has no statewide bicycle helmet law for any age, and no Mississippi municipality currently has a published bicycle-helmet ordinance. CPSC certification still applies to every helmet sold in the state under federal law (16 CFR Part 1203).

Statute

—

Confirm equipment fit with the helmet size calculator before relying on an age rule alone.

Statewide rule

Defers to local rules

Notes

Mississippi's bicycle code (Miss. Code §§ 63-3-1301 to 63-3-1321) does not address sidewalk cycling, and Miss. Code § 63-3-1303 makes cyclists subject to the rules of the road only when on a roadway. Sidewalk regulation is left to municipalities - Jackson and Hattiesburg prohibit sidewalk riding in their business districts; Oxford permits it citywide except where signed.

Statute

¹

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

Penalty

Mississippi's DUI statute (Miss. Code § 63-11-30) applies to anyone operating a 'vehicle.' Miss. Code § 63-3-1303 makes every bicycle rider subject to all duties applicable to the driver of a vehicle when on a roadway. The first-offense penalty mirrors the motor-vehicle DUI: fine up to $1,000, possible jail, and a driver-licence suspension that applies even though no motor vehicle was involved.

Statute

¹²

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.
