What action should be taken if your car breaks down on the highway?

When your car breaks down on the highway, staying in the vehicle with your hazard lights on and calling for help is the safest course of action. This approach keeps you within a protected space, reducing the risk of being involved in an accident, especially on busy highways where traffic can be unpredictable.

By activating your hazard lights, you alert other drivers to your situation, helping to prevent collisions. Staying in the car also keeps you from exposing yourself to potential dangers associated with moving traffic. It's advisable to wait for a professional to assist you, as they possess the tools and expertise to handle vehicle issues safely.

The other options may put you at a greater risk, such as trying to exit the highway or fix the car yourself, which may not be safe without the proper knowledge or tools. Likewise, leaving the car and walking to the nearest exit could place you in a hazardous situation with traffic, increasing the chances of injury. Therefore, remaining in the vehicle while seeking assistance is the most prudent decision.
