Home › CDL Practice Tests › Combination Vehicles Questions › Question 148
What should you do if you must stop on a slippery surface and your wheels begin to lock repeatedly?
- A.Keep increasing pressure until the vehicle stops, whatever the wheels do
- B.Reduce brake pressure, slow down more gradually, and increase following distance so you never need a hard application
- C.Shift into neutral to make the lockups stop
- D.Turn the steering wheel back and forth while braking
Correct answer
B. Reduce brake pressure, slow down more gradually, and increase following distance so you never need a hard application
Why
Repeated lockup is feedback that you are asking for more grip than the surface offers. Backing off the pressure and planning much gentler, earlier stops keeps the combination rolling and under control.
