ABS & Anti-Skid

If ABS fails partway through a trip, how should your braking technique change?

  • A.Keep using maximum pedal pressure in every stop because nothing changed
  • B.Use only the trailer hand valve for the rest of the trip
  • C.Stop checking your mirrors when braking
  • D.Brake as you would in a vehicle without ABS, avoiding wheel lockup by easing off if a skid starts, and have the system repaired soon
Correct answer

D. Brake as you would in a vehicle without ABS, avoiding wheel lockup by easing off if a skid starts, and have the system repaired soon

Why

Losing ABS returns lockup control to the driver's foot and judgement. Smooth, controlled braking and greater following distance replace the automatic protection until the fault is fixed.
