Where do large vehicles create air turbulence at high speeds?

Large vehicles, such as trucks and buses, create air turbulence at high speeds in various areas due to their size and shape, which disrupts the flow of air around them. This turbulence can occur directly in front of the vehicle, alongside the cab, and by the back area of the trailer.

Directly in front of the truck, the large surface area pushes air aside, creating a disturbance that affects the air pressure and flow in the vicinity. This can lead to a significant influence on vehicles that are following closely behind, as they may experience a sudden shift in airflow.

Alongside the cab, air turbulence is generated as the vehicle moves, disrupting the smooth flow of air, which can create wind gusts that affect any adjacent vehicles. This turbulence impacts the stability and control of vehicles that are riding close to the sides of large trucks.

By the back area of the trailer, as the air moves past the rear, it creates a vacuum or low-pressure region that can draw other vehicles into it, potentially making them unstable if they are too close. The design of the trailer can accentuate this phenomenon.

Because turbulence can occur in all these areas, the answer encompasses the combined effects of air disturbance around large vehicles, making it accurate to say all of the
