SUBJECT 4 · EMERGENCY AVOIDANCE
When the front wheels lock during braking, steering capability may be lost.
ANSWER · A
"Lock up" means the braking system (whether disc or drum) grips the tire so it cannot rotate; the car slides on the road like a brick. With wheels locked, steering is lost. Modern cars have ABS to prevent wheel lock during emergency braking, allowing the driver to keep steering control. When ABS engages, the driver feels strong pulsation underfoot but can still steer. The statement is correct.
