For most that have emergency assistance, the solution if your car stalls or if you have a flat tire is a phone call away. For others, it can be an unnerving and stressful experience.
If you encounter another vehicle that has stalled, call 911 to report that vehicle (if you have a cellular phone). If you are driving on the roads, be aware of your surroundings not just the car in front of you. Watch for brake or hazard lights and help alert other drivers by tapping your brakes and slowing down. If you see a patrol car weaving back and forth across lanes of traffic with lights on, do not try to pass, it is slowing traffic because of a problem ahead.
