QAC Right-of-way Exam
1. What is the primary goal of right-of-way vegetation management?
A. To eliminate all plant life in the area
B. To create an aesthetically pleasing environment
C. To maintain visibility and safety while protecting infrastructure
D. To encourage the growth of native plants only
Answer: ✅ C. The primary goal is to maintain visibility and safety, prevent fire
hazards, and protect infrastructure like roads, pipelines, and power lines.
2. What is the main concern when applying herbicides near aquatic environments
along rights-of-way?
A. Drift onto road surfaces
, B. Weed resistance
C. Leaching into drinking water supplies
D. Impact on non-target aquatic organisms
Answer: ✅ D. The impact on non-target aquatic organisms is a significant concern
when working near water bodies.
3. Which of the following is an example of a selective herbicide application?
A. Applying herbicide to an entire area using aerial spray
B. Using a wiper applicator on only broadleaf weeds
C. Blanket spraying with non-selective herbicide
D. Soil sterilization across a railroad track
Answer: ✅ B. A wiper applicator targets specific weed types, which makes it
selective.
4. What environmental factor is most likely to increase pesticide drift during
application?
A. Low humidity
B. High wind speed
C. Overcast skies
D. High soil moisture
Answer: ✅ B. High wind speed can carry pesticides away from the target area,
increasing the risk of drift.
5. What is the best way to minimize the development of herbicide-resistant weeds?
A. Use only pre-emergent herbicides
B. Apply herbicides at reduced rates
C. Rotate herbicide modes of action
D. Apply herbicides more frequently
Answer: ✅ C. Rotating herbicide modes of action is essential in preventing
resistance.
6. What is the definition of a non-selective herbicide?
