Sidewalk riding
- Statewide rule
- Allowed with conditions
- Notes
- La. R.S. 32:197(C) prohibits riding a bicycle on a sidewalk within a business district. Outside business districts there is no statewide ban, but cities and parishes may regulate further. New Orleans prohibits sidewalk riding in the French Quarter and Central Business District; Baton Rouge defers entirely to the state rule. Where sidewalk riding is allowed, riders must give an audible signal before passing pedestrians.

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

- Penalty
- Louisiana's DWI statute (La. R.S. 14:98) applies to operators of a 'motor vehicle, aircraft, watercraft, vessel, or other means of conveyance.' Louisiana courts have consistently held that the residual 'other means of conveyance' clause does not reach bicycles, and a cyclist cannot be charged with DWI in the state. Public-intoxication and disturbing-the-peace charges remain available for impaired riders.
- Statute
- 1
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.
