Crash responders keep our roads safe.

Each year, they clear more than 6 million crashes and remove stalled vehicles, debris, and other hazards.

Slow down, move over - it's the law.

When approaching a work or response vehicle with flashing lights, move over a lane or slow down to at least 10 mph below the posted speed limit.

Their safety starts with you!

Nationally, nearly every week a responder is killed while clearing a roadway. Slow down and move over to keep our crews safe.
