How does a truck escape ramp work?
Most escape ramps make use of arrester beds, pools of sand or gravel. The material in the bed is selected for their low coefficients of interparticle friction, meaning when a wheel or axle touches the bed, the material in it moves away from each other, allowing the truck to sink into the gaps.

What are the 4 causes of skidding?
A skid is usually caused by one of three things: either oversteering, when the driver makes a sharp turn and then attempts to straighten up too quickly; an excessive use of the car’s brakes, causing the vehicle’s wheels to lock up; and from accelerating the car while still in mid-turn.
