What the move over law requires in California
The duty to change lanes, when you must slow down instead, which vehicles are covered, and the penalties for a violation.
California move-over fines, the added penalty assessments, and the list of covered vehicles are amended often. Confirm the current figures and covered vehicles for your citation date before relying on them.
| What the law requires | What it means |
|---|---|
| Move over a lane | Before you pass in the lane immediately next to the stopped vehicle, Vehicle Code section 21809 requires a lane change into an available lane that is not immediately adjacent, with due regard for safety and traffic, when that is practicable and not prohibited by law. |
| Slow down if you cannot | If changing lanes would be unsafe or impracticable, you must slow to a reasonable and prudent speed that is safe for the weather, road, and traffic conditions. The statute does not set a fixed number below the limit. |
| Covered vehicles | The duty applies to a stationary authorized emergency vehicle displaying emergency lights, a stationary tow truck displaying flashing amber warning lights, and a stationary marked Department of Transportation (Caltrans) vehicle displaying flashing amber warning lights. |
| Where it applies | The rule applies on a highway when the covered vehicle is stationary and adjacent to the roadway. It does not apply where the vehicle is not adjacent to the highway or is separated from it by a protective physical barrier. |
| Penalties and enhancements | What it means |
|---|---|
| Base fine range | A violation is an infraction. The statutory base fine is not more than $50, but court penalty assessments and fees raise the actual amount owed well above the base, and a violation adds one point to the driving record. |
| Causing injury or death | Section 21809 does not create its own injury or death grade. A driver who strikes a responder or a stopped vehicle can face separate charges, such as reckless driving or vehicular manslaughter, and civil liability, depending on the facts. |
| Directed by an officer | The lane-change and slow-down duty applies absent other direction by a peace officer. Follow an officer directing traffic at the scene even if that differs from the default rule. |
What you can do right now
Concrete, neutral steps for the road and for a ticket in California. This is legal information, not legal advice.
- Know the covered vehicles
Learn to spot the flashing amber lights on tow trucks and Caltrans vehicles, not just the red and blue lights on emergency vehicles, so you react in time.
- Move over early
Check your mirrors and signal for a lane change as soon as you see a stopped vehicle ahead, so a merge is still safe. Slow down only if the lane will not clear.
- Contest a ticket if you have grounds
If you believe a lane change was unsafe or the vehicle was behind a barrier, you can raise that in traffic court. A lawyer referral service can point you to help.
A move over violation is a traffic offense, and it becomes far more serious if a responder is hurt. A licensed traffic attorney can explain your options; the state bar can refer you to one.

What drivers in California get wrong about the move over law
California's move-over rule is in Vehicle Code section 21809. When you drive on a highway toward a stationary authorized emergency vehicle showing emergency lights, a stationary tow truck showing flashing amber lights, or a stationary marked Caltrans vehicle showing flashing amber lights, you must approach with due caution. Before you pass in the lane right next to it, you have to change into a lane that is not immediately adjacent when that is safe and practicable. If a lane change would be unsafe or is not possible, you instead slow to a reasonable and prudent speed for the conditions. A violation is an infraction with a base fine of not more than $50, though penalty assessments push the real cost higher, and it adds one point to your record. The section does not set its own injury or death penalty. A driver who hits a responder or a stopped vehicle can face separate charges such as reckless driving or vehicular manslaughter, plus civil liability. The duty does not apply where the stopped vehicle sits behind a protective barrier or is not next to the highway. This is legal information, not legal advice.
