What should a driver do when making a U-turn?

When making a U-turn, it is crucial for a driver to thoroughly check for traffic, pedestrians, and ensure overall visibility. This practice is vital to ensure the safety of all road users. By checking for traffic, the driver can avoid collisions with oncoming or crossing vehicles. Ensuring the absence of pedestrians is equally important, as pedestrians might unexpectedly cross the street, especially in urban areas. Additionally, confirming good visibility means the driver can see both their surroundings and any potential hazards clearly, making the maneuver safer.

The other choices do not encompass the comprehensive assessments needed before executing a U-turn. Only checking for pedestrians or traffic behind the vehicle neglects potential hazards that may arise from the front or the sides. Making the turn quickly without checking is unsafe and increases the risk of accidents. Thus, the correct approach involves a complete situational awareness to promote safety and prevent mishaps during the maneuver.
