The suspension becomes less effective at high speed.
The brakes cannot remove water from the tyres.
The vehicle becomes heavier as speed increases.
✓ The tyres have less time to clear water from the road surface.

At higher speeds, the tyres may not disperse water effectively, making it easier for the vehicle to lose contact with the road.
