How should you start moving on an icy surface from a stop?
- A.Accelerate very gently in as high a gear as practical to avoid spinning the drive tires
- B.Spin the tires to melt through the ice
- C.Use full throttle in the lowest gear
- D.Rock the truck aggressively until it moves
Correct answer
A. Accelerate very gently in as high a gear as practical to avoid spinning the drive tires
Why
Excess torque simply polishes the ice and digs the tires in, after which even chains struggle. A gentle start that keeps the tires gripping, even if progress is slow, is the technique that actually moves the rig.
