When your vehicle breaks down on the highway, the best course of action is to move it to the side of the road if possible, turn on your hazard lights, and remain inside the vehicle. This approach helps ensure your safety and that of other road users.
Parking the vehicle on the shoulder makes it less likely to obstruct traffic, which is important for maintaining safety on the highway. Turning on hazard lights signals to other drivers that you are experiencing an issue, alerting them to proceed with caution around your vehicle. Staying inside the vehicle is crucial because it provides a barrier between you and oncoming traffic, reducing the risk of injury should other vehicles not notice your stalled car in time.
The other options are less safe; for instance, continuing to drive could lead to a more dangerous situation if the vehicle breaks down completely or causes a crash. Leaving the vehicle without ensuring a safe location may expose you to traffic hazards. Parking in the middle of the lane is not only dangerous but could lead to collisions, putting both you and other drivers at risk.
