Skids are caused by hard braking , abrupt acceleration, or

travelling too fast, doing a very aggressive or sudden turn, or bad conditions of the road.

Explanation:

Skidding is the slip of the wheels over the road caused by loss of traction between the tires and the pavement.

When the tires slip, they lose their grip on the ground and tend to move according to the inertia or the imperfections of the surface instead of following the desired route. So, the driver is not in control of the vehicle any more.

The traction is how hard the wheels are attached to the ground, whenever you are forced to brake hard, accelerate abruptly, make a sudden turn or the surface of the road is covered with water, sand, or oil, the wheels will not adhere enough to the road and the car skids.

Also the conditions of the tires are important: when the tires lose their design, they will not have the capacity to displace the water and will slide easilyover wet surfaces.
