During last year’s Memorial Day weekend enforcement operations, the CHP arrested roughly 1,100 motorists on suspicion of drunken or drug-impaired driving, a figure similar to 2023. Forty-two vehicle occupants were killed in collisions investigated by the CHP and other agencies during the 2024 effort — four below the number who died in 2023.

Law enforcement agencies are setting up DUI checkpoints and conduct extra patrols through the holiday weekend.

As travelers head to their destinations, the California Highway Patrol is ramping up patrols to make sure you have a safe holiday.
