Correct answer: A skid caused by taking a turn too fast.
ABS helps with brake-induced wheel lock. It does not make excessive cornering speed, close following or poorly maintained brakes safe, and it does not guarantee a shorter stop.

If an emergency-exit lock is fitted to a Missouri school bus, what safeguard must its design provide?
Correct answer: The engine cannot start while the emergency exit is locked.
