What factors reduce traction?
Slippery surfaces reduce traction and a tire's ability to exert the force needed to control the truck – which increases braking distance. Wet roads can double the time it takes to stop your truck, and of course the slicker the surface the longer it takes to come to a stop at a given speed.
What is main cause 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.
