Which system is crucial for maintaining stability during braking?

Anti-lock braking system
Power steering system
Fuel injection system
Suspension system

The correct answer is: Anti-lock braking system

The anti-lock braking system (ABS) is essential for maintaining stability during braking, especially in emergency situations or on slippery surfaces. ABS prevents the wheels from locking up by automatically modulating the brake pressure during hard braking. This allows the driver to maintain steering control while braking, reducing the risk of skidding and allowing the vehicle to stop more safely and effectively. When wheels lock up during braking, the vehicle can slide, causing the driver to lose control. By preventing this from happening, ABS enhances the vehicle’s overall stability, enabling the driver to navigate while braking. This is particularly important in trucks and transport vehicles, which are typically larger and heavier, making them more challenging to control during sudden stops. The other systems mentioned, such as the power steering system, fuel injection system, and suspension system, play important roles in vehicle function but do not directly address stability during braking. Power steering aids in maneuverability, the fuel injection system manages the engine's fuel delivery, and the suspension system affects ride quality and handling. While all of these systems contribute to a vehicle's overall performance, they do not have the specific function of maintaining stability during braking like the anti-lock braking system does.
