How can you make it easier to drive a passenger car out of a sticky snow?

When the car is stuck in soft snow, the most effective way to get out is to rock it: you reverse and move forward in turn, and each movement makes the track you have driven a little longer, until the wheels get out of the hole - answer A. You pull away gently, in a higher gear and at low revs, so that the wheels do not spin.

Pulling away at high revs (B) and releasing the clutch sharply (C) only make the wheels spin, and they dig in deeper and deeper, while the hot rubber melts and polishes the snow under the tyre. It is worth first clearing the snow from around the wheels, putting something under them that will improve grip, and in a car with traction control, switching it off while you get out.
