What is off-tracking?

Off-tracking occurs because the rear wheels of a large vehicle have a longer turning radius than the front wheels. As a result, the rear wheels will swing wider around a corner. The amount of off-tracking increases as the vehicle's wheelbase increases and the corner becomes tighter. Off-tracking can be a hazard, especially when driving on narrow roads or when there is oncoming traffic. It is important to be aware of off-tracking when driving a large vehicle and to take appropriate measures to avoid accidents.
