What effect does a large vehicle passing a small vehicle at high speed have on the smaller vehicle driver?

When a large vehicle passes a small vehicle at high speed, the primary effect experienced by the smaller vehicle driver is air turbulence and noise. As the large vehicle moves through the air, it displaces a significant volume of air, creating a turbulent wake behind it. This turbulence can cause the smaller vehicle to sway or experience an abrupt shift in stability, which can be particularly disconcerting for the driver. Additionally, the sound generated by the large vehicle, along with the noise from the wind rushing around, can be overwhelming and distracting, making it difficult for the smaller vehicle driver to focus.

This phenomenon is particularly noticeable when larger trucks overtake smaller cars or when they are traveling in close proximity. The combination of turbulence and noise can heighten the driver’s awareness and concern about their vehicle's stability, leading to increased tension and focus on maintaining control of the vehicle. Understanding this is crucial for drivers as it can influence their driving behavior, prompting them to increase following distance and be more cautious when larger vehicles are nearby.
