What should a driver do if their vehicle breaks down on the highway?

When a vehicle breaks down on the highway, the safest and most appropriate action is to pull over to the side of the road and turn on hazard lights. This choice promotes safety by alerting other drivers about the presence of a stationary vehicle, which helps prevent accidents. Additionally, pulling over ensures that the vehicle is not obstructing traffic, thereby reducing the risk of further complications.

By activating hazard lights, the driver indicates to others that they are experiencing an issue, which is crucial for maintaining safety on the roadway. This proactive step can help other drivers navigate around the disabled vehicle safely.

In contrast, stopping in the middle of the lane poses a significant danger, as it obstructs traffic and increases the likelihood of collisions. Continuing to drive with a malfunctioning vehicle can exacerbate the problem and endanger both the driver and other road users. Leaving the vehicle may not be safe, especially in high-speed areas, and can expose the driver to increased risk from passing traffic. Therefore, the recommended choice focuses on safety and effective communication with other drivers.
