When driving a bus in strong gusts of wind, which measure is appropriate to reduce air resistance and maintain stability?

Question

DentroTest · Accepted Answer

The aerodynamic drag that a vehicle experiences grows exponentially with speed. In the case of a bus, because of its large side and front surface, strong wind generates considerable forces that severely compromise directional stability. Reducing speed directly decreases the force of air resistance and the push of the gusts, making it easier for the driver to control the vehicle's path and increasing the reaction time for possible involuntary deviations. By contrast, accelerating would drastically increase aerodynamic drag and the danger of rollover or running off the road. Likewise, getting too close to the vehicle ahead breaches the mandatory safety distance and poses a serious risk of rear-end collision.
