What can restrict your line of sight while driving?

Curves on the road can significantly restrict your line of sight while driving because they can block your view of oncoming traffic, pedestrians, and road hazards. When navigating a curve, it may be difficult to see what lies ahead, making it essential to approach such areas with caution and reduced speed. This lack of visibility can lead to unsafe driving situations, as all drivers need to be fully aware of their surroundings to react appropriately.

Other drivers, traffic signals, and pavement conditions also play roles in overall driving safety, but they do not inherently restrict your line of sight in the same direct manner that road curves do. For instance, while other drivers may momentarily obstruct your view, it's typically not a consistent issue like the gradual loss of sight due to a curve. Similarly, traffic signals are usually positioned to be visible in advance, and pavement conditions affect vehicle traction rather than visibility directly.
