Why must vegetation within the ROW be controlled?

• A. To maintain sight lines, drainage, and prevent obstruction of signs and devices
• B. To improve aesthetics
• C. To promote wildlife habitat
• D. To reduce maintenance costs

Answer: (A)

Vegetation within the ROW must be controlled to keep essential safety features clear and functional. When plants grow into the area, they can narrow sight lines around curves or intersections, make it harder to judge stopping distances, and obscure signs and devices that guide drivers or indicate hazards. It’s also important to keep drainage paths open; overgrown plants can block ditches or culverts, leading to water buildup or erosion that affects roadway safety. While aesthetics, wildlife habitat, and maintenance cost are considerations in broader land-management planning, they aren’t the primary reason for vegetation control in the ROW—the focus is on maintaining visibility, proper drainage, and the readability and visibility of signs and devices that keep the roadway safe.
