ANSWERS | LATEST EXAM
1. Winter Storm Response Staffing Conflict
Your city is expecting a severe winter storm in 24 hours. You ask your streets
maintenance crew to prepare plow attachments and salt spreaders. One senior
operator refuses overtime, claiming he has “family obligations” and saying the
city “should have hired more staff instead of overworking the same people.” His
refusal influences two junior operators to say they also prefer not to work
overtime.
As the supervisor, what is the best response?
A. Tell all staff that overtime is mandatory and refusal will be documented as
insubordination.
B. Meet with the senior operator privately, explain operational priority, remind
him of policy, and work to secure minimum staffing while addressing concerns
professionally.
C. Reassign the storm work to other divisions and avoid the conflict entirely.
D. Allow the three operators to skip overtime but note this for future
performance reviews.
Correct Answer: B
Explanation: Supervisors must maintain service readiness while managing
morale. Mandatory messaging without conversation (A) risks escalation.
Avoiding action (C or D) compromises safety and reliability. A private
conversation clarifies expectations, policies, essential-service duty, and helps
address underlying issues.
2. Roadway Repair Contract Dispute
A contractor resurfacing a major arterial submits a change order claiming
“subsurface instability” requiring additional gravel. Your inspector’s notes state
the subgrade looked normal. The city engineer says the contractor may be
inflating costs.
,What should you do first?
A. Reject the change order immediately.
B. Conduct a site verification with photos, inspector notes, and geotechnical
data to determine validity.
C. Approve the change order to keep the project on schedule.
D. Ask the contractor to reduce the requested amount.
Correct Answer: B
Explanation: Supervisors must conduct due diligence before accepting or
rejecting claims. Verification ensures fairness, protects city funds, and
documents conditions.
3. Public Complaint About Mowing Standards
A resident complains that roadside mowing is “uneven and sloppy,” claiming it
creates hazards. When reviewing the crew’s work, you find that equipment
blades are dull and the operator skipped sections to save time.
What is the most appropriate supervisory action?
A. Reassign the operator for the rest of the season.
B. Conduct coaching, retrain on standards, sharpen equipment, and document
corrective action.
C. Apologize to the resident and have a different crew redo the work.
D. Ignore the complaint because the missed areas are minor.
Correct Answer: B
Explanation: Supervisors correct performance issues through coaching +
equipment maintenance + documentation. Replacement (A or C) avoids
addressing root causes. Ignoring (D) damages public trust.
4. Utility Strike Risk During Excavation
Your crew is preparing to excavate for a culvert replacement. The utility locate
tickets show an old gas line might be nearby. The GIS map conflicts with the
field markings, and your foreman is confident the line is “probably deeper.”
What should you do?
A. Proceed carefully with excavation.
B. Pothole/test-dig to physically confirm the utility location before continuing.
,C. Call the gas company and let them handle excavation.
D. Proceed but assign an extra spotter.
Correct Answer: B
Explanation: When maps and field markings conflict, physical verification
(potholing) is required for safety and compliance. Excavating without
confirmation risks catastrophic damage.
5. Low Productivity on a Drainage Maintenance Crew
You notice a crew assigned to clean catch basins is completing only 40% of the
normal weekly workload. GPS data shows long idle periods between sites.
What is the best leadership approach?
A. Discipline the crew for poor performance.
B. Conduct a time-motion study and ride-along to identify workflow or
equipment problems.
C. Replace the crew supervisor immediately.
D. Reduce the workload expectations for this cycle.
Correct Answer: B
Explanation: Data-driven assessment identifies whether slow performance is
due to equipment, route planning, training gaps, or individual behavior.
Discipline without diagnosis (A) is premature.
6. Safety Violation During Asphalt Operations
You arrive onsite during asphalt paving and notice two workers standing within
the loader’s swing radius. The foreman says “they know what they’re doing”
and waves off your concerns.
What is your best action?
A. Stop work immediately and remove the foreman.
B. Stop the unsafe activity, review the job hazard analysis, retrain on spotter
procedures, and document the incident.
C. Allow the crew to continue but schedule safety training next month.
D. Report the foreman to HR and leave.
Correct Answer: B
Explanation: Supervisors must intervene immediately when hazards are
, observed, correct the unsafe behavior, ensure retraining, and document. Extreme
punishment (A or D) is not appropriate unless repeated.
7. Asset Replacement Budget Justification
Your fleet includes a 20-year-old dump truck with high downtime and repair
costs. Finance questions your replacement request and asks for detailed
justification.
What is the most appropriate response?
A. Argue that the truck is old and dangerous.
B. Provide a life-cycle cost analysis comparing continued repair vs.
replacement, including risk and service impacts.
C. Request a political advocate to pressure finance.
D. Drop the request and hope for approval next year.
Correct Answer: B
Explanation: CPWP-S supervisors use data-based justification. Lifecycle
analysis supports defensible budgeting.
8. Conflict Between Two Crew Members Affecting Work
Two crew members constantly argue, slowing productivity. Each claims the
other is disrespectful. Other staff avoid working with them.
What is the best supervisory intervention?
A. Separate them permanently and assign different shifts.
B. Conduct individual interviews, identify root causes, mediate resolution, and
set behavior expectations.
C. Ignore the conflict unless it becomes physical.
D. Write both employees up immediately.
Correct Answer: B
Explanation: Supervisors are responsible for conflict resolution through fact-
gathering, mediation, and expectation setting. Documentation may follow if
problems continue.
9. Citizen Demand for Immediate Pothole Repair
