In terms of visibility, what should you do when approaching an intersection?

When approaching an intersection, it's crucial to ensure maximum visibility and to assess the surrounding environment effectively. Scanning rapidly in all directions allows a driver to identify any potential hazards from multiple angles, including vehicles, pedestrians, bicycles, and other obstacles that may come from any direction.

This proactive scanning helps ensure that the driver can react appropriately to any situations that may arise, such as a vehicle running a red light or a pedestrian unexpectedly crossing the street. It underscores the importance of situational awareness, which is vital for safe driving, especially at intersections where the likelihood of encounters with other road users is high.

The other options do not promote the same level of safety or awareness. Increasing speed can lead to reduced reaction time and less ability to respond to sudden changes in the environment. Decreasing speed is beneficial when approaching intersections, but it should be complemented with a comprehensive scan of the area. Looking only to the right restricts the driver's field of view and ignores the potential hazards that could come from the left, straight ahead, or behind. Thus, scanning rapidly in all directions is the most effective strategy for maintaining safety at intersections.
