California's Move Over law now covers any stopped car with hazards

Last updated

Since January 1, 2026, California's Move Over law reaches beyond emergency vehicles, tow trucks and Caltrans trucks. It now covers any stopped vehicle that shows flashing hazard lights or another warning device, such as cones, flares or reflective triangles.

What to do on the road

When you come up on a stopped vehicle with hazard lights or warning devices, approach with care. If it is safe and possible, change into a lane that is not next to it. If you cannot, slow down to a speed that is safe for the conditions.

What changed

Until the end of 2025 the rule covered stopped emergency vehicles, tow trucks and marked Caltrans vehicles with their warning lights on. Assembly Bill 390 added marked highway maintenance vehicles and any other stopped vehicle with hazards or warning devices, so a family car stopped with a flat tire and its hazards on counts too.

When it does not apply

The rule does not apply when the stopped vehicle is not next to the highway, or when a protective barrier separates it from traffic.
