RoadsideAvoid Erosion, Flooding and Line-of-Sight Problems on Roadsides
Weeds and other vegetation like to make their home along roadsides. There are a number of reasons to control this roadside vegetation: ensuring motorist safety and maintaining line of sight, allowing for proper drainage of precipitation thereby preventing road surface degradation, and preventing the spread of invasive species onto adjacent properties.

It is essential that vegetation does not block traffic signs or roadside markers. Because vegetation can obstruct driver vision at intersections or block the line of sight around curves, it must be treated and controlled — and roadside herbicides play a vital role. It is especially important that roadside delineators and traffic signs can be seen in poor conditions to ensure motorist safety. Excessive vegetation also can damage roadbeds by obstructing drainage off the surface, leading to potholes, flooding and other hazards.
