In the example, we wind up with 0.819. WebStep 6. The turning radius (alternatively, turning diameter or turning circle) of a vehicle defines the minimum dimension (typically the radius or diameter, respectively) of available space required for that vehicle to make a semi-circular U-turn without skidding. The turning path of a Single-Unit Truck or Bus measures the minimum possible turning radius necessary for performing a u-turn in a vehicle with a 20 (6.1 m) wheelbase.
