What is the purpose of controlled braking in a vehicle?

A. Enhance fuel efficiency
B. Improve road grip
C. Keep the vehicle in a straight line when braking
D. Reduce engine noise

The correct answer is: C. Keep the vehicle in a straight line when braking

The primary purpose of controlled braking in a vehicle is to keep the vehicle in a straight line when braking. This technique allows the driver to apply the brakes in a manner that maintains stability and control, especially in situations where sudden stops are necessary or when driving on slippery surfaces. By ensuring that the vehicle continues to travel straight, controlled braking helps prevent skidding and loss of control, which can lead to accidents. While factors like fuel efficiency, road grip, and engine noise may be relevant in other driving contexts, they do not directly describe the primary function of controlled braking. Enhancing fuel efficiency or reducing engine noise is not directly associated with the method of braking; instead, controlled braking focuses on the vehicle's handling and stability during the braking process.
