If your car gets stuck in deep snow and can’t get out, it’s pointless to stay there and doggedly step on the gas. This will just make it worse. If the car “won’t move”, first try backing up – this is usually much easier than going forward. If this doesn’t help, try moving back and forth, or rocking the car by giving it short bursts of gas in the rhythm of the car’s movement. Transferring the weight of the car between the axles might help find that missing piece of traction. If you can’t get out with the wheels turned straight, try rotating the steering wheel in different directions.
