What should a driver do if they are stopped on a highway?

When a driver is stopped on a highway, turning on hazard lights is essential for safety. Hazard lights serve as a warning signal to other drivers, indicating that the vehicle is either stationary due to a problem or an emergency situation. This visibility can prevent accidents by alerting approaching vehicles to slow down or maneuver around the stopping vehicle.

Additionally, the other options are not advisable. For instance, getting out of the vehicle immediately can pose a significant risk, especially on highways where traffic is moving at high speeds. Leaving the vehicle unlocked might also increase the risk of theft or provide unintended access, while driving away quickly could lead to further accidents or legal consequences, particularly if the vehicle is disabled or stopped for legitimate reasons. Thus, activating hazard lights is the safest and most prudent action for a driver stopped on a highway.
