What action should you take if your car breaks down on the highway?

When your car breaks down on the highway, the safest and most responsible action is to move your vehicle to the shoulder and turn on your hazard lights. This action helps to ensure your safety as well as the safety of other drivers. Moving to the shoulder of the road places your vehicle out of the main traffic flow, reducing the risk of collisions. Activating the hazard lights alerts other drivers that your vehicle is disabled and should be approached with caution.

If other options were to be considered, waiting in the car without visibility or warning may put both the driver and others at risk. Attempting to repair a vehicle on the highway can expose you to danger from passing traffic, and driving to a service station in a potentially malfunctioning vehicle could lead to further issues and risk. Hence, moving to the shoulder and using hazard lights is the most effective and safety-conscious decision in this scenario.
