Motorcycles are likely to be ____ by the aerodynamics surrounding tractor-trailers.

Due to the light weight of motorcycles and bicycles, they are prone to be negatively affected by the wind created by large vehicles, such as semitrailers, tractor-trailers, and buses. The aerodynamics can pull motorcycles toward the larger vehicle. For everyone's safety, be sure to use extra caution when passing a two-wheeled vehicle while operating a large CMV.
