What causes a vehicle to skid on the roadway?
- Quick wear of the clutch and of the gearbox.
- Correct answer: When the braking forces or the vehicle's inertia exceed the tire’s ability to grip of the roadway.
- Excessive change of gears.
- When the engine is worn out and cannot stabilize the vehicle.
Why this is the answer
The correct answer in the official bank: When the braking forces or the vehicle's inertia exceed the tire’s ability to grip of the roadway.
A skid happens when the forces acting on the vehicle, such as hard braking or the vehicle's inertia in a bend or sudden change of direction, become greater than the grip of the tyres on the road. Grip drops on wet or slippery roads and with worn tyres, so slow down and brake gently. Worn engines, clutches or gearboxes are not the direct cause of skidding.
