What action should be avoided if the engine stalls while driving?

Answer: B — Braking suddenly

When an engine stalls while driving, braking suddenly is an action that should be avoided. Sudden braking can lead to a loss of vehicle control, especially if the vehicle is traveling at a significant speed. It can also increase the risk of rear-end collisions if other drivers are following closely behind. When an engine stalls, the driver typically has lost power steering and power brakes, making it difficult to stop quickly without creating a dangerous scenario. Instead, it is advisable to gradually reduce speed and steer the vehicle to a safe location, such as the side of the road, while maintaining control of the vehicle. The correct action involves a measured response, rather than a sudden one, which aids in maintaining safety for both the driver and other road users.
