How many feet of unobstructed visibility should be available for a safe place to turn around?

A safe place to turn around requires 500 feet of unobstructed visibility to ensure that the driver can see far enough ahead to make a safe maneuver. This amount of visibility allows the driver to observe oncoming traffic and any potential hazards in the area, providing enough time and space to make informed decisions without the risk of an accident.

In situations such as school bus turns where safety is paramount, this visibility is crucial. It enables the driver to anticipate the movement of other vehicles and pedestrians, particularly in school zones where children may be present. Ensuring that this distance is clear of any obstacles helps to mitigate risks associated with turning maneuvers, allowing for a smoother and safer operation of the bus.
