What is the first step in handling a mechanical failure while driving?

The correct response emphasizes the importance of safety and situational assessment when experiencing a mechanical failure while driving. By signaling and pulling over safely, a driver can effectively evaluate the issue without putting themselves or others in danger. This step allows for a methodical approach to understanding the problem, ensuring that any potential hazards are minimized.

Continuing to drive until reaching a garage might exacerbate the situation, possibly leading to further mechanical failure or increased risk on the road. Exiting the vehicle immediately can be dangerous, especially if the vehicle is still in motion or if it’s pulled over on a busy road without assessing the surroundings. Calling for assistance without stopping neglects the necessary safety protocols, as it can distract from the immediate need to bring the vehicle to a safe stop. Overall, pulling over safely first sets a foundation for a responsible and cautious evaluation of the mechanical failure.
