The term "turning radius" refers to how sharply you can turn the front wheels of your vehicle. This measurement is crucial for understanding how much space a vehicle requires to make a turn without colliding with obstacles. A smaller turning radius indicates that a vehicle can maneuver more sharply, which is particularly important in tight urban environments or when navigating narrow roads.

The other options touch on related aspects of vehicle dynamics but do not define turning radius accurately. The distance between the front and rear wheels is related to the vehicle's wheelbase, which affects stability and handling but does not directly measure how sharp a turn can be. The angle of the steering wheel is important for initiating a turn but does not define the radius itself, as it varies based on different factors including vehicle size and type. Finally, the speed at which you can safely turn is influenced by many factors, including turning radius, but speed itself is not a measure of turning radius. Understanding turning radius helps drivers navigate effectively and is especially beneficial for drivers operating larger vehicles, like those requiring a Class 4 Commercial Driver's Licence.
