Earthquake Safety While Driving

Gradually slow down and pull off to the shoulder when safe. Avoid stopping under overpasses. Turn on hazard lights and remain in the vehicle. After the shaking stops, check for road damage before proceeding. Move away from freeway on-ramps where bridge structures are present.

Yes. Strong earthquake shaking can make it difficult to control a vehicle, and other drivers may panic and brake suddenly. Ground movement can open sinkholes beneath road surfaces, shift bridge decks, or cause immediate road damage. Reduce speed immediately when you feel shaking and pull over when safe.

After a major earthquake, roads may be damaged, congested with emergency traffic, or blocked by debris. Emergency services prioritize road clearance, but surface damage may not be immediately visible. Drive slowly and cautiously. Avoid bridges until they have been inspected. Follow emergency route guidance from local authorities.

If you are approaching a bridge or overpass when shaking begins, slow down and pull as far right as safely possible — do not attempt to cross a bridge that is shaking. If you are already on the bridge, cross quickly if shaking is just starting. After a major earthquake, assume all overpasses and bridges are damaged and avoid them until inspected.

A car provides some protection from falling debris but is not as structurally strong as a building. If you are outside and cannot reach a building safely, sitting in your car with the windows up and seatbelt on is better than standing in the open under overhead hazards. After shaking stops, remain in your car if near overhead power lines.
