ABS brakes are designed to prevent what and maintain the ability to do what?

The correct answer highlights that ABS (Anti-lock Braking System) brakes are specifically engineered to prevent the tires from locking up during hard braking situations. When tires lock, they lose traction with the road surface, which can lead to a loss of control over the vehicle. This is particularly critical in emergency stops or on slippery surfaces.

By preventing the tires from locking, ABS allows the driver to maintain steering control, which is crucial for maneuvering the vehicle in emergency situations. This ability to steer while braking helps drivers avoid obstacles and stay safe on the road, enhancing overall vehicle stability during abrupt stops. This function is central to the design and purpose of ABS, making it a valuable safety feature in modern vehicles.
