Question

Difficulty: MediumWindy Conditions

Accelerating to a higher road speed when travelling across open, wind-swept areas improves vehicle stability because increased forward momentum prevents the car from being pushed sideways by sudden gusts.

Answer: Answer

Answer

False
The statement is false because increasing road speed in severe crosswinds severely compromises vehicle stability. Higher speeds amplify aerodynamic buffeting, decrease tyre grip margins, and reduce the time the driver has to react and make smooth steering corrections when hit by unexpected gusts.

Step-by-Step Solution

1
Evaluate the relationship between vehicle speed and aerodynamic forces in strong winds.
Higher speed increases aerodynamic turbulence and amplifies the lateral force exerted by crosswinds.
Vehicle handling in windy conditions is governed by aerodynamic effects that scale non-linearly with road speed.
2
Assess the effect of road speed on driver reaction time and lateral deviation.
Travelling faster dramatically shortens the time available to detect and smoothly correct course deviations.
Maintaining vehicle control during sudden buffeting requires moderate speeds and measured steering corrections rather than abrupt inputs.
