From my sand driving experience (1), if you have no paddle tyres, keep your car moving!!! or you will get bogged. Be wary of sand as it gets EVERYWHERE!! I covered my electric motor with nylon stockings as suggested and no sand in the motor (hooray!!). but if using petrol, get sand in the carburettor and there goes your engine (and 200$). But do it right and it'll be an experience to remember
