The Federal Highway Administration encourages roadway agencies to adopt roadside vegetation management programs that identify the best maintenance practices for each location. An integrated approach includes:
- Cutting (mechanical and hand)
- Use of herbicides
- Grazing of livestock
- Cultivating desirable vegetation
Essentially, drivers have to be able to see and navigate the road clearly. If overgrowth of vegetation blocks a driver’s view of roadway signs or oncoming traffic, the municipality in charge of maintenance could find itself facing a car accident lawsuit.
