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).
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.
