The amount your rear wheels will go 'off-track' while turning is influenced by which factor?

The amount your rear wheels will go 'off-track' while turning is influenced significantly by the distance between the front and rear wheels, often referred to as the wheelbase of the vehicle. In a bus, a longer wheelbase typically results in a greater 'off-tracking' effect during a turn. This is because as the vehicle turns, the rear wheels follow a different path compared to the front wheels. The longer the vehicle, the more pronounced this effect becomes, leading to increased cornering arcs and potential clearance issues when navigating turns.

The weight of the bus influences handling and stability but does not directly dictate the rear wheel path while turning. Similarly, the bus's length overall would affect turning dynamics, but it's the wheelbase that specifically determines how much the rear wheels will track inside the front wheels' path. The width of the bus does not directly contribute to the rear wheel offset during a turn; rather, it relates more to overall stability and space requirements while navigating turns. Understanding these dynamics is crucial for ensuring safe turning maneuvers, especially in larger vehicles like buses.
