What should a driver do in the event of a vehicle malfunction on the highway?

In the event of a vehicle malfunction on the highway, the most appropriate action is to move to the shoulder if possible and turn on hazard lights. This response serves multiple important functions.

Firstly, moving to the shoulder provides a safer environment for both the driver and other road users. The shoulder is typically a designated area for vehicles to pull over in emergencies, minimizing the risk of collisions with moving traffic. Secondly, activating hazard lights alerts other drivers that your vehicle is in distress and that they should approach with caution. This visibility helps prevent additional accidents and ensures that other road users are aware of your situation.

Choosing to continue driving at a slower speed could exacerbate the problem, potentially leading to a complete breakdown in a traffic lane, which poses a danger to yourself and other drivers. Stopping immediately in the middle of the road is highly unsafe as it blocks traffic and increases the likelihood of an accident. While calling the police for assistance can be appropriate after establishing a safer location, it is crucial first to ensure the vehicle is out of the traffic flow. Therefore, moving to the shoulder and turning on hazard lights is the best immediate course of action during a vehicle malfunction on the highway.
