No, Louisiana does not have a specific law banning cursing while driving. Claims about such a rule appear to stem from misattributed “bizarre driving laws” lists that actually reference Rockville, Maryland, where swearing from a vehicle within earshot of others is a misdemeanor punishable by up to $100 fine or 90 days in jail.​
Louisiana’s Relevant Law
Louisiana’s disturbing the peace statute (La. R.S. 14:103(A)(2)) prohibits addressing offensive, derisive, or annoying words to others in public places, which could theoretically apply if cursing from a vehicle foreseeably disturbs the public. This is a misdemeanor with fines up to $100 and/or up to 90 days in jail, but courts often deem it unconstitutional under the First Amendment when it targets protected speech like profanity without inciting immediate breach of peace.​
Enforcement Context
Such charges are rare for isolated cursing while driving and typically require intent to annoy or disrupt, not just venting frustration. Road rage involving threats or reckless driving may trigger separate charges like careless operation, but profanity alone isn’t criminalized specifically for vehicles.​
Similar Laws Elsewhere
Profanity remains illegal under outdated statutes in states like Alabama, Mississippi, North Carolina, and South Carolina, though often unenforceable. Maryland’s Rockville rule is the closest match to the headline’s description, not Louisiana.
