What should a driver do if their vehicle becomes disabled on the highway?

When a vehicle becomes disabled on the highway, the safest course of action is to move the vehicle to the shoulder if possible and turn on the hazard lights. This approach prioritizes the safety of both the driver and other road users. By moving to the shoulder, the vehicle is out of the main traffic flow, reducing the risk of collisions. The hazard lights signal to other drivers that there is a problem, alerting them to navigate safely around the disabled vehicle.

Staying inside the vehicle is not advisable without taking precautionary measures, especially if the vehicle is in a potentially dangerous position on the road. Attempting to fix the vehicle immediately can expose the driver to traffic hazards and may be impractical without proper tools or training. Leaving the vehicle to walk for help can also be dangerous, as it may increase the risk of an accident or leave the driver vulnerable in a public space. Therefore, moving to the shoulder and activating hazard lights ensures the best safety practices for all involved.
