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

When a vehicle breaks down on the highway, moving the vehicle to the shoulder and using hazard lights is the safest and most effective response. This action helps to ensure the safety of both the driver and other road users. By moving to the shoulder, the driver reduces the risk of being involved in a secondary collision or obstructing traffic, which can be particularly dangerous on high-speed roads.

Utilizing hazard lights is crucial as it alerts other drivers to the situation, indicating that the vehicle is not in motion and that caution is required to avoid any accidents. This practice of signaling assists in creating more awareness and allows other drivers to navigate around the disabled vehicle safely.

On the other hand, stopping in the middle of the lane creates significant hazards for the driver and others by blocking traffic flow. Leaving the vehicle to seek help may increase risk, especially in a busy highway setting, as walking along the roadside can expose the individual to dangers from oncoming traffic. Turning off the ignition and checking under the hood could be unsafe if the vehicle is in a high-traffic area, as well. Hence, moving to the shoulder and using hazard lights is the most responsible and secure choice when faced with a breakdown on the highway.
