Impaired Driving
In Louisiana, operating a motor vehicle after consuming alcohol or other impairing substances remains a major cause of vehicle crashes, serious injuries, and fatalities. According to LSU Center for Analytics & Research in Transportation Safety data, in 2024, 26% of fatal motor vehicle crashes in Louisiana were alcohol-related, and the number of alcohol-impaired crash fatalities was 201. In 2025, the percentage of alcohol-related crashes in Louisiana increased to 27%. The number of alcohol-related crash fatalities in 2025 rose to 211.
State and local law enforcement officials work year-round to identify impaired drivers and get them off our roads. The Louisiana Highway Safety Commission supports the National Highway Traffic Safety Administration's "Drive Sober or Get Pulled Over" campaign to combat impaired driving. LHSC provides support to law enforcement agencies to conduct sobriety checkpoints and saturation patrols throughout the year.
