What happens to visual lead at higher speeds for drivers?

At higher speeds, the visual lead increases. This is because drivers need to see further ahead to effectively assess and respond to potential hazards and make timely decisions. As speed increases, the distance covered in a given time also increases, thus drivers must expand their visual lead to ensure they can react appropriately to obstacles, other vehicles, and traffic signals.

In practical terms, having a greater visual lead allows drivers to maintain a safe stopping distance and respond more effectively to changes in the driving environment. This is particularly important for school bus drivers, who must be vigilant about the safety of their passengers and the surrounding pedestrians, especially children. Therefore, it's crucial that they adjust their visual lead according to their speed to allow for adequate reaction time.
