Once a car digs in, more throttle only buries the tyres deeper. Stop, get out and look at what the wheels are resting on. Dubai Police advise adjusting tyre pressures before driving on sand and engaging four-wheel drive where the car has it; lowering pressure spreads the tyre and helps it float rather than cut in.
Scoop sand away from in front of each wheel, push recovery boards under the tyres and ease forward gently. If the car is resting on its chassis, stop before the clutch or gearbox overheats and let a recovery crew pull it back to firm ground.
