ATSSA TRAFFIC CONTROL SUPERVISOR TESTS ACTUAL EXAMS
QUESTIONS WITH CORRECT ANSWERS 2026/2027( A GRADED
100% VERIFIED)
A state highway agency is preparing to rehabilitate a six-lane divided urban arterial
with multiple signalized intersections, heavy pedestrian activity, frequent transit
stops, and an average daily traffic volume exceeding 60,000 vehicles. The
contractor proposes closing two inside lanes in each direction during daytime
hours to accelerate production. As the Traffic Control Supervisor (TCS), your
primary responsibility is to ensure the Temporary Traffic Control (TTC) plan
minimizes crash risk while maintaining mobility for motorists, pedestrians,
bicyclists, and transit users. Before approving the proposed lane closures, which
action should receive the highest priority?
A. Verify that the TTC plan complies with applicable MUTCD principles,
accommodates all road users, and maintains safe traffic operations throughout
each construction phase.
B. Increase posted work zone speed limits to reduce congestion and improve
traffic flow.
C. Remove advance warning signs because drivers can clearly see the work area
from a distance.
D. Allow the contractor to modify traffic control devices without prior approval to
improve productivity.
Answer: A
Explanation: The TCS is responsible for ensuring the TTC plan complies with
MUTCD guidance and protects all road users. Safety always takes precedence
over production or convenience.

Question 2
During an overnight freeway paving operation, you observe that a taper extending
traffic from two lanes into one is significantly shorter than the length specified in
the approved traffic control plan. Drivers are braking abruptly and making sudden
lane changes upon approaching the closure. What is the most appropriate
immediate action?
A. Continue monitoring because traffic volumes are lower at night.
B. Lengthen the taper to match the approved design and applicable standards
before continuing operations.
C. Reduce the number of warning signs to encourage drivers to merge sooner.
D. Wait until the next scheduled inspection before making adjustments.
Answer: B
Explanation: Incorrect taper lengths can create hazardous merging conditions.
The taper should be corrected immediately to reduce crash risk and comply with
the approved TTC plan.
Question 3
A contractor requests permission to store construction equipment within the clear
recovery area adjacent to an open travel lane because it would reduce equipment
movement and improve efficiency. As the Traffic Control Supervisor, what is the
most appropriate response?
A. Approve the request if equipment is equipped with flashing lights.
,3|Page
B. Permit storage only during daylight hours.
C. Deny the request unless the equipment is properly protected or located outside
the clear zone in accordance with the approved TTC plan.
D. Allow storage if workers remain nearby.
Answer: C
Explanation: Equipment within the clear zone presents a fixed-object hazard. It
should either be removed from the recovery area or protected using approved
measures.
Question 4
While inspecting a work zone, you notice several channelizing devices have been
displaced by traffic, leaving motorists uncertain about the intended travel path.
Which action best demonstrates effective Traffic Control Supervisor
responsibilities?
A. Leave the devices until the end of the work shift.
B. Replace and realign the devices immediately to restore positive guidance.
C. Reduce the work zone speed limit by another 10 mph.
D. Ask motorists to merge using portable message boards only.
Answer: B
Explanation: Maintaining positive guidance is one of the TCS's primary duties.
Displaced devices should be corrected immediately.

Question 5
A utility contractor begins excavating within the work zone before all advance
warning signs have been installed. Several motorists unexpectedly encounter the
excavation area and stop suddenly. What should the Traffic Control Supervisor
have required before authorizing work?
A. Installation of all required temporary traffic control devices according to the
approved plan before work begins.
B. Excavation first, followed by signs as work progresses.
C. Only a flagger at the excavation.
D. Workers wearing high-visibility apparel.
Answer: A
Explanation: Temporary traffic control must be fully established before exposing
motorists to work zone hazards.
Question 6
A multilane freeway work zone experiences dense fog that reduces visibility to
less than 300 feet. Which action provides the safest response?
A. Maintain the existing setup because it was approved previously.
B. Evaluate conditions, enhance visibility measures where appropriate, and
consider suspending operations if adequate safety cannot be maintained.
C. Remove warning signs to avoid confusing motorists.
