Move Over Laws & Roadside Workers

Police officers, firefighters, EMTs, tow operators, road crews and stranded drivers are struck and killed on highway shoulders every year. Every state has a move over law that requires drivers to change lanes or slow down when passing stopped emergency and service vehicles.

• All drivers
• Roadside workers

What the laws require

When you approach a stopped vehicle with flashing lights on the side of the road:

1. Move over one lane away from the stopped vehicle, if you can do so safely.
2. If you can’t move over safely, slow down well below the speed limit. Some states set a specific amount (such as 20 mph under the limit).

Which vehicles

All states cover police, fire and ambulance vehicles. Most also cover:

• Tow trucks and roadside assistance vehicles
• Highway maintenance and road construction vehicles
• Utility trucks
• In a growing number of states, any stopped vehicle with hazard lights on

The safest habit: move over or slow down for every vehicle stopped on the shoulder.

Doing it safely

• Look far ahead for flashing lights so you have time to plan.
• Signal and check mirrors and blind spots before moving over.
• Don’t slam on the brakes or swerve suddenly.
• Don’t stare at the scene; “rubbernecking” causes crashes.
• Give extra room to trucks and large vehicles on the shoulder.

If you’re the one stopped

Get as far off the road as possible, turn on your hazard lights, and stay away from the traffic side of your vehicle. See Breaking Down on the Highway.

Penalties

Violations can bring fines, points and, in some states, license suspension, especially if someone is hurt. More important: a tow operator or officer goes home safe.
