If your vehicle is trapped on a slippery or sandy road, the best thing to do is to stay calm and try to assess the situation. If you're stuck in a rut, try rocking the car back and forth to get some traction. If you're on a sandy road, try digging out the tires so they have something to grip onto. In both cases, it's important to avoid spinning the tires, as this will only make the situation worse.
