The science behind aquaplaning
This dangerous skidding is caused by the action (or inaction) of key forces
At slower speeds the tyres are able to shift the water away from the surface of the road and the surface of the wheel.
Full road contact
At slower speeds the tyres manage to keep in full contact with the road so the driver can manoeuvre safely through the wet conditions.
At moderate speeds the tyres are still able to move most of the water and, while traction is reduced, grip remains.
Reduced road contact
Reduced road contact can result in some loss of control and may cause a vehicle to slide around a bit.
At higher speeds the treads on tyres are unable to shift the water between the tyre and the road, causing the tyres to lose all traction and the driver to lose control of the vehicle.
When the water isn’t removed by the tyres the pressure increases in front of the tyres as it gathers there instead. Eventually the water wedges underneath the tyre, lifting the vehicle and causing it to glide along the road.
