If you get stuck in the snow and you are in a fairly safe area, dig the snow away from all the wheels. Work slowly and don't over exert yourself

Put traction pads or pieces of carpeting, or scraps of cardboard under both drive wheels. Spread sand, rock salt, ashes or kitty litter under the tires. Then gently, keeping your wheels straight, rock the car back and forth by changing from forward to reverse, increasing the distance travelled with each rock.

Use gentle accelerator pressure. If your car is automatic, brake when shifting from drive to reverse or vice versa, to avoid damaging the transmission.
