What should you do if your vehicle breaks down on the highway?

Remaining in your vehicle and waiting for help is the safest choice if your vehicle breaks down on the highway. Staying in your vehicle protects you from potential hazards such as passing traffic, and it provides a stable environment while you await assistance. If your vehicle is on the side of the road and you are in a safe spot, it is also more visible to other drivers, which can help prevent further accidents.

Additionally, vehicles often provide shelter from the weather and a means to communicate for help, particularly if you have a mobile phone. It's crucial to stay in your vehicle until help arrives, especially on busy highways, to minimize the risk of injury.

The other options may expose the driver to unnecessary risks. Leaving the vehicle can put you in jeopardy, especially if there's traffic. Attempting to fix the vehicle on the spot can also be dangerous depending on the circumstances. Calling for a tow truck from the middle of the road may not be advisable, as it can put you in a precarious situation amongst moving vehicles.
