Question

Large vehicles traveling at high speeds create air turbulence in which of the following areas:

a. Directly in front of the truck.
b. Alongside the cab.
c. By the back area of the trailer and at the immediate rear of the trailer.
d. All of the above.

Answer 1

Large vehicles create air turbulence in all areas around them when traveling at high speeds. A heavily loaded trailer would bounce less because the greater mass results in a more stable suspension system.

Step-by-step explanation:

Large vehicles traveling at high speeds create air turbulence in all of the areas described: directly in front of the truck, alongside the cab, and by the back area of the trailer and at the immediate rear of the trailer. The turbulences are caused by the vehicle disrupting the airflow, forming swirls and eddies as higher-speed layers of air mix with the slower surrounding layers. A heavily loaded trailer would have less noticeable bouncing compared to an empty one because the mass dampens the oscillation of the trailer's suspension system, making it more stable.
