ABS & Anti-Skid

Why should you not rely on ABS to prevent a skid when entering a curve too fast?

  • A.ABS works on braking wheels and cannot restore the side grip lost when speed exceeds what the curve and surface allow
  • B.ABS only works in curves, never on straight roads
  • C.Curves turn the ABS controller off
  • D.ABS adds grip to the outside tires in a turn
Correct answer

A. ABS works on braking wheels and cannot restore the side grip lost when speed exceeds what the curve and surface allow

Why

Antilock control can keep a braking wheel rolling, but a vehicle that is simply going too fast for the turn can slide or roll without any brake application. Setting curve speed before entry remains essential.
