What happens when a vehicle's engine stalls while driving?

When a vehicle's engine stalls while driving, it signifies a failure in vehicle control. This situation can arise from various factors, such as a mechanical issue, fuel supply problem, or electrical failure. When the engine stalls, it loses power, which affects the driver's ability to steer and brake effectively. The vehicle may drift to a stop, presenting safety risks, especially if it happens in traffic or at high speeds. Therefore, recognizing that engine stalling represents a loss of control is crucial for understanding safe driving practices and vehicle maintenance.

The other options suggest positive outcomes or skills that do not occur when a vehicle stalls, as it can lead to dangerous situations rather than enhancing performance or indicating driver proficiency.
