Introduction

This guide explains traffic bylaws and enforcement in Baton Rouge, Louisiana, focusing on speed limits, right-of-way rules, and driving under the influence (DUI) controls. It summarizes where the rules come from, who enforces them locally, common violations, and the practical steps to contest tickets, apply for permits, or report dangerous driving. Use the official municipal code and law enforcement contacts listed in Resources to confirm current text and procedures. For quick reference, municipal traffic provisions and local ordinances are consolidated in the City-Parish code and local police guidance.[1]

Speed Limits

Speed limits in Baton Rouge are set by ordinance for local streets and follow state law for highways and state routes. Local posted limits apply on city-parish streets; unposted urban residential streets commonly default to posted local limits or state default speeds where state law applies. School zones, work zones, and special reduced-speed areas are posted and enforced under local ordinance and state statute. Drivers should obey posted signs and variable messages from traffic control devices.

Always follow posted signs; unposted defaults may be governed by state law.

Right-of-Way

Right-of-way rules in Baton Rouge conform to the Louisiana traffic code for intersections, pedestrian crossings, and turn maneuvers. Yielding to pedestrians in marked crosswalks and obeying traffic-control devices is required. Local ordinances may add parking and stopping restrictions that affect right-of-way near schools, emergency facilities, and construction zones.

DUI Rules

Driving under the influence (DUI or DWI) is prosecuted under Louisiana criminal statutes and enforced locally by Baton Rouge police and state troopers. Local officers may make stops, conduct field sobriety tests, and arrest for probable cause; administrative license actions are handled through the state motor vehicle authority. Municipal code enforces local traffic stops, towing, and impound procedures following arrest or citation.

DUI enforcement follows state criminal and administrative procedures alongside local enforcement.
