Which type of vehicle is identified as the largest Vision Barrier?

The largest Vision Barrier among the options provided is identified as a truck. Trucks are generally larger and taller than the other vehicle types listed, such as motorcycles, compact cars, and SUVs. This size creates a more significant obstruction in the line of sight for other drivers and pedestrians.

In particular, trucks often have higher profiles, which can obstruct views of smaller vehicles, cyclists, and pedestrians, creating blind spots that can lead to dangerous situations. The sheer size and design of trucks mean they can block visibility more substantially compared to compact cars or motorcycles, which are typically much smaller and sit lower to the ground. This enhanced height makes it more challenging for surrounding drivers to see what is happening in front of and around the truck, thus being classified as the largest Vision Barrier.

Though SUVs are larger than compact cars, they do not match the considerable size and bulk of trucks, which is why they do not serve as the most significant obstruction in terms of visibility.
