Which active safety system prevents the wheels from locking when braking hard?

Question

DentroTest · Accepted Answer

The correct answer is the ABS braking system (Anti-lock Braking System). Detailed explanation: ABS is an active safety system that uses sensors to detect if the wheels stop rotating (lock up) while braking. If this happens, the system automatically reduces and increases brake pressure intermittently (you will feel a vibration in the pedal). Main advantage: By preventing locking, the wheels do not skid on the asphalt, allowing the driver to maintain steering control to dodge obstacles while braking hard. Without ABS, with locked wheels, the car would continue in a straight line due to inertia, disregarding steering inputs. Why the other options are incorrect:   The servo brake (brake booster): This is a mechanism that helps the driver press the brake pedal with less physical effort, but it does not prevent locking.   Integral traction (AWD): Helps with grip when accelerating (distributing drive power), not when braking.
