What effect does an oncoming heavy vehicle have on a motorcycle rider?

Answer: A — The wind will suck you towards the vehicle, then push you away

When a heavy vehicle approaches, it displaces a significant amount of air due to its size and speed. As it moves, it creates a vacuum effect in its wake; this can initially pull a motorcycle towards it, which can create an unsteady feeling for the rider. Once the motorcycle passes the vehicle, the wind then pushes away from the vehicle, which can affect the rider's stability. Understanding this dynamic is vital for motorcycle safety, as it underscores the importance of maintaining a safe distance from large vehicles, especially when they are overtaking or being overtaken. This knowledge helps riders to anticipate potential changes in their trajectory and adjust their positioning accordingly to maintain control.
