Question: 1 / 400

What is the term for a commercial vehicle's tendency to swing wide on turns?

Backtracking

Offtracking

The term that describes a commercial vehicle's tendency to swing wide on turns is offtracking. This phenomenon occurs because of the articulation of the vehicle, especially in vehicles with multiple axles and trailers. When a commercial vehicle makes a turn, the rear wheels (or wheels of the trailer) do not follow the exact path of the front wheels. Instead, they follow a wider arc, which can create a discrepancy in the path that the two sets of wheels travel.

Understanding offtracking is crucial for drivers of large vehicles to navigate turns safely, ensuring they don't encroach on other lanes or collide with obstacles such as curbs, traffic signs, or pedestrians. This concept emphasizes the importance of spatial awareness and proper turning techniques when operating larger vehicles.
