Before a vehicle operator performs a U-turn, what should they ensure?

Before a vehicle operator performs a U-turn, ensuring that the path is clear to the front, side, and rear is crucial for safety. This precaution helps to avoid collisions with other vehicles, pedestrians, or obstacles that may not be immediately visible. By checking all around the vehicle, the operator can assess the environment and make an informed decision on whether it is safe to proceed with the maneuver. This practice minimizes risks and enhances situational awareness, which are essential for safe driving in busy environments like an airfield.

The other options, while relevant to vehicle operation and safety, do not directly address the inherent risks associated with executing a U-turn, making clear visibility around the vehicle the primary concern in this scenario.
