Bicycle Helmet Laws in Louisiana

The rule
Louisiana requires a bicycle helmet for any rider under the age of 12. The same rule extends to children carried as passengers in a child seat or trailer. La. R.S. 32:199 requires every bicycle operator and passenger under 12 to wear a properly fitted and fastened helmet that meets ANSI, Snell, or ASTM standards. Violation is a non-moving infraction; the maximum fine is $50 and may be waived if the parent or guardian shows proof of helmet purchase to the court. See La. R.S. 32:199 (Bicycle helmets required for persons under twelve). Read the national helmet laws guide for comparison. Confirm equipment fit with the helmet size calculator before relying on an age rule alone.
Statute
What this means in practice
If you're 12 or older, Louisiana doesn't require you to wear a helmet by state law. Riders under 12 (and any child carried as a passenger) must wear a helmet that meets the ANSI Z90.4, Snell B-90, or ASTM (a CPSC-certified helmet meets these specifications) standard.
Cities can be stricter than the state floor, and bike-share systems often require helmets regardless of age. If you're renting or commuting in a major city, confirm the local rule before you ride.
Get the fit right
Find your CPSC-certified helmet size
A helmet that meets the law but does not fit will not protect you. Measure your head circumference, then shop a size band you can trust.
