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

When a commercial vehicle breaks down on the road, the most appropriate action is to turn on hazard lights and stay in the vehicle. This practice is essential for several reasons. First, hazard lights signal to other drivers that the vehicle is experiencing an issue, thereby increasing visibility and reducing the risk of a collision. Staying inside the vehicle provides a safer environment for the driver, especially if the breakdown occurs on a busy or high-speed road where exiting could expose them to danger from passing traffic.

Remaining in the vehicle is generally recommended unless there is a specific reason to leave, like an unsafe situation within the vehicle. Additionally, staying put allows the driver to be more easily located by roadside assistance or emergency services if they are called. This action also minimizes potential disruptions that could occur from being out on the roadway, ensuring a more controlled response to the breakdown situation.

The other options—leaving the vehicle, contacting emergency services immediately, or attempting to fix the vehicle on the spot—introduce various risks and complications that are typically best avoided in these scenarios.
