If your engine fails while you are driving the first thing to do is?

If your engine fails while driving, the first thing to do is to remain calm and safely maneuver the vehicle to the side of the road or a safe area away from traffic. Once stopped, turn on your hazard lights to alert other drivers. Then, assess the situation and, if necessary, call for roadside assistance or a tow truck. Always prioritize your safety and that of others on the road.
