Key takeaways

  • The Move Over law requires drivers to slow or shift lanes for stopped emergency and service vehicles.
  • Call CHP or 911 for any accident, injury, or unsafe location.
  • Never stop on a bridge or in a tunnel unless there's no alternative.
  • Winter storms and coastal fog change the safe-stopping calculus.

The Move Over law

California requires drivers to move over one lane or slow to a safe speed when approaching a stopped emergency vehicle, tow truck, Caltrans vehicle, or roadside service truck with flashing amber lights. This is why our techs work as far right as possible — but they still depend on other drivers to comply.

CHP vs roadside service

Call 911 or CHP for accidents, injuries, unsafe locations (blind curves, no shoulder), or if you feel personally unsafe. Call a roadside service like Go Ape for mechanical breakdowns in safe stopping locations.

Weather in San Diego County

Coastal marine layer can cut visibility hard — slow down and use low beams. Winter storms on the mountain routes (SR-79, I-8 east of Alpine) can bring ice and require chains. Always give yourself extra following distance in the rain during Southern California's first storm of the season.

Frequently asked questions

Do I need to call CHP before a roadside service comes?

Not usually — but you should call CHP first for any accident, injury, or an unsafe stopping location.

Is Go Ape a CHP call-box responder?
