What should you do if your car breaks down on a highway?

Using 4-way flashers to warn others is the appropriate action if your car breaks down on a highway. Activating your hazard lights signals to other drivers that your vehicle is stationary and may pose a danger. This increases safety not only for you but also for other road users, as it alerts them to approach with caution. It's particularly important on highways where speeds are higher, and the risk of an accident is elevated.

In contrast, simply calling for help and waiting without indicating your situation may not inform other drivers of your presence, which could lead to collisions. While driving to the nearest exit sounds practical, it's often unsafe to move a disabled vehicle unless it can be done without risk. Leaving the vehicle immediately can expose you to potential hazards, especially on busy highways. Therefore, signaling with your 4-way flashers is essential in this situation to enhance safety for everyone involved.
