Answer:
A. You're stopped on the side of the road with an engine that
won't start.
Step-by-step explanation:
Hazard lights are used to signal other drivers that your vehicle is a temporary obstruction, like when a vehicle is broken down or won't start. You should never use your hazard lights when parked dangerously or illegally. You should also avoid using hazard lights when driving, unless it is to signal other drivers of an obstruction ahead.
