What is the most common cause for a vehicle to skid:
Because the tyres are worn
Because of pedestrians or other drivers
Because of other people's actions
Explanation: Worn-out tyres can also develop bulges and blisters that create weak spots on their surfaces. These can increase the chances of a sudden blowout, and can also lead to skidding, hydroplaning, or losing control of your car by reducing the tyre's ability to grip the road.
