1 Dig sand away from all the wheels.
2 Use second gear and do not rev the engine too hard. If you have a manual car, gently ‘feather’ the clutch to ‘creep’ forwards.
3 Try to have people push from behind at the same time.
4 If you’re still stuck, lower air pressure in your tyres to approx 15 psi for better traction.
5 If you’re still struggling, try all of the above plus try turning the steering wheel quickly from side to side.
6 If you’re still stuck, find someone to tow you out gently, after digging-out as per the above.
