At its tightest turning angle, the rear overhang of the back bumper extends out to 43.3 feet. 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 required turning radius of a fire apparatus access road shall be:. Additional clearances should be provided whenever possible to accommodate a larger variety of car sizes and driver abilities. The turning radius is determined by the space needed to turn your wheel all the way in one direction from the straight-ahead position. Your submission has been received! To perform a U turn in a forward direction only, the centre of the turn is not coincident with the centre of the road - thus a complete circle would not be possible (without driving onto the pavement to complete the manoeuvre). Turn Larger radii are also desirable where speed reductions would cause problems. Bus Turning Radius The distance from the first mark to the furthest mark is your turning circle, or the space your vehicle needs to do a U-turn without hitting a curb. 1. control devices.
