What is defined as the front overhang of a bus?

The front overhang of a bus is defined as the distance measured from the hub of the front tire to the front bumper. This measurement is important because it indicates how far the front of the bus extends beyond the point of contact with the ground (the front tires). Understanding this dimension is crucial for various operational factors, including maneuvering in tight spaces, ensuring safe turns, and maintaining appropriate following distances in traffic.

In contrast, other choices refer to different measurements or points on the bus. One option describes the rear overhang, which pertains to the area behind the rear axle, while others reference distances that do not accurately define the front overhang as specified in the question. Recognizing the precise definition helps in various aspects of bus operation, safety, and maintenance.
