turning circle
Vehicle's pivot arc
The turning circle is the smallest circular space a vehicle needs to make a complete U-turn.
It measures from curb to curb or wall to wall, depending on whether you're counting just the tires or the full body swing.
A tight turning circle makes city driving and parking easier: The London taxi's famous turning circle lets it navigate narrow streets.
