When operating a vehicle, which of the following represents the proper distance to see while making a U-turn?

When making a U-turn, it's essential to have adequate visibility of the roadway and surrounding environment to ensure the maneuver can be completed safely. A distance of 500 feet is typically recommended because it allows the driver to see oncoming traffic, pedestrians, and any obstacles that may be present. This distance provides a clear view of the area to gauge the safety of making the turn and ensures that the driver has enough time to react to any potential hazards. By being able to see 500 feet ahead, a driver can assess the flow of traffic and determine if it is safe to proceed, contributing to safe driving practices and reducing the risk of accidents while executing the U-turn.
