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.

Strong crosswinds begin pushing your school bus sideways. What is the appropriate response?
