What should I do while waiting on the shoulder?
Get the hazards on first, before anything else. If the vehicle is on a highway shoulder and there is a barrier, the safest place to wait is usually behind it rather than inside the car, because a stopped vehicle on a shoulder is the thing that gets struck. If the car is in a live lane and cannot be moved, that is a call to police rather than to us — no roadside repair is safe with traffic passing at speed. On a residential street or in a parking lot, staying with the vehicle is fine.
