To stop a drive-wheel skid, you should:
  • Stop braking and let the wheels roll
  • Countersteer
  • All of things are part of the process
  • Turn the wheel quickly
Click here to look up the answer

From The CDL Manual

Do the following to correct a drive-wheel braking skid:

  • Stop braking – This will let the rear wheels roll again and keep the rear wheels from sliding any further. If on ice, push in the clutch to let the wheels turn freely.
  • Turn quickly – When a vehicle begins to slide sideways, quickly steer in the direction you want the vehicle to go— down the road. You must turn the wheel quickly.
  • Countersteer – As a vehicle turns back on course, it has a tendency to keep right on turning. Unless you turn the steering wheel quickly the other way, you may find yourself skidding in the opposite direction.

Front-Wheel Skids —

Most front-wheel skids are caused by driving too fast for conditions. Other causes are lack of tread on the front tires, and cargo loaded so not enough weight is on the front axle. In a front-wheel skid, the front end tends to go in a straight line regardless of how much you turn the steering wheel. On a very slippery surface, you may not be able to steer around a curve or turn.
