Final answer:
Trees and shrubs can limit visibility near roadways, making the statement true. Proper roadside maintenance is required to manage this vegetation and ensure driver safety.
Step-by-step explanation:
Trees and shrubs growing near the roadway can indeed limit visibility, which would make the statement true. Vegetation near roads can obstruct a driver's view of oncoming traffic, road signs, animals, or other hazards. This is especially critical at intersections, bends, or any points on the road where full visibility is necessary for safety. It's important for roadside maintenance to include management of plant overgrowth to ensure safe driving conditions. Moreover, overgrown foliage can sometimes shield wildlife or pedestrians from view, increasing the risk of accidents. Adequate visibility is crucial for drivers to respond to their surroundings and navigate safely.
This limitation in visibility is due to the physical characteristics of trees and shrubs. Tall trees with dense foliage can block or filter light, casting shadows across the road, creating blind spots for drivers. Similarly, shrubs with thick vegetation can also impede visibility, especially if they are positioned close to the roadway.
For example, in a deciduous forest, the canopy of tall trees block sunlight from reaching the ground, preventing the growth of smaller plants and limiting visibility. The photo of a landscape with shrubs, dormant grass, a few trees, and mountains in the background also demonstrates how the presence of shrubs and trees can impact visibility.
