SECTION 1: GENERAL RIGHT-OF-WAY KNOWLEDGE (Questions
1–20)
1. Rights-of-way are defined as areas set aside for use in
common transport, including which of the following?
A. Golf courses and residential lawns
B. Federal, state, county, and municipal highways; public airports;
, Page 2 of 47
and railroads
C. Private agricultural fields and orchards
D. National parks and wilderness areas
Correct Answer: B
Rationale: Rights-of-way are areas set aside for common transport,
including federal, state, county, and municipal highways and roads,
public airports, and railroads. Private agricultural fields, golf
courses, and national parks are not considered rights-of-way.
2. Which of the following is the primary goal of right-of-way
vegetation management?
A. Eliminate all plant life from the right-of-way
B. Promote wildlife habitat exclusively
C. Maintain safe, functional access and visibility
D. Increase soil fertility along roadsides
Correct Answer: C
Rationale: Right-of-way work focuses on safety, access, visibility,
and infrastructure protection—not total vegetation removal. The
primary reasons for managing vegetation along roads include the
safety of the motorist, the condition of the pavement, and
aesthetics.
3. Which situation best illustrates the primary objective of
vegetation management along a highway shoulder where
invasive annual weeds are beginning to reduce driver visibility
and create fire hazards?
A. Allowing vegetation to mature naturally so that wildlife habitat is
maximized regardless of safety concerns
B. Reducing hazardous, obstructive, or invasive vegetation while
, Page 3 of 47
protecting nearby people, crops, water, and desirable plants
C. Applying herbicides at the highest labeled rate to eliminate all
plant growth permanently
D. Treating only ornamental plants because right-of-way work does
not include roadsides
Correct Answer: B
Rationale: Right-of-way pest control focuses on managing
vegetation that interferes with transportation, utility, safety, and
access functions while minimizing environmental and off-target
impacts.
4. Which site is considered a right-of-way?
A. Golf course
B. Road shoulders and utility corridors
C. Vegetable farm
D. Residential lawn
Correct Answer: B
Rationale: Roadways, railways, pipelines, and utility lines are
classic right-of-way sites. Golf courses, vegetable farms, and
residential lawns are not rights-of-way.
5. Broadleaf weeds and grasses along the shoulders of roadways
can cause:
A. Increased soil fertility
B. The edges of the pavement to break up
C. Improved drainage
D. Enhanced wildlife habitat
Correct Answer: B
Rationale: Broadleaf weeds and grasses along the shoulders of
, Page 4 of 47
roadways can cause the edges of the pavement to break up. Weeds
and grasses can also catch and hold soil, which may restrict water
flow from the pavement surface.
6. Which of the following is a reason why trees and brush must
be managed near electrical power lines?
A. They improve the aesthetic value of the corridor
B. They may cause a power shortage and grounding
C. They provide wildlife habitat
D. They prevent soil erosion
Correct Answer: B
Rationale: Trees and brush may cause a power shortage and
grounding when allowed to grow near electrical power lines.
Vegetation management along utility corridors is essential for
maintaining reliable power delivery and preventing outages.
7. Weeds, grasses, and brush may obstruct which of the
following on rights-of-way?
A. Only visibility for drivers
B. Bridges, road signs, and runway landing lights
C. Only drainage ditches
D. Only pedestrian walkways
Correct Answer: B
Rationale: Weeds, grasses, and brush may obstruct bridges, road
signs, and runway landing lights. Obstruction of these features
creates safety hazards for motorists, pedestrians, and aircraft.
8. What is the primary purpose of right-of-way pest control?
A. Enhancing aesthetic value of public lands
B. Preventing the spread of pests along transportation corridors
