1. During a temporary traffic control operation on a high-speed Maryland
roadway, a certified technician observes that advance warning signs
are placed too close together, reducing motorists’ perception-reaction
time and increasing the likelihood of abrupt lane changes. According
to principles contained in temporary traffic control planning and the
Manual on Uniform Traffic Control Devices, which corrective action
should the technician implement first to improve driver expectancy
and reduce crash potential?
A. Remove all warning signs except the one closest to the work zone
B. Increase spacing between advance warning signs to correspond with
roadway speed and conditions
C. Replace warning signs with portable message boards only
D. Position flaggers immediately adjacent to the taper without additional
signage
B. Increase spacing between advance warning signs to correspond with
roadway speed and conditions
Proper sign spacing allows drivers adequate time to perceive hazards,
process information, and react safely. Higher-speed facilities require
,greater distances between warning signs to maintain driver expectancy
and reduce sudden braking or erratic maneuvers near the work zone.
2. A traffic control technician is assigned to establish a lane closure on a
multilane divided highway during nighttime maintenance operations.
The technician must determine the safest sequence for placing
channelizing devices and advance warning signs while minimizing
worker exposure to moving traffic. Which procedure is considered the
safest and most appropriate?
A. Install the taper first and then place signs after traffic slows down
B. Begin setup closest to the work area and proceed upstream toward
approaching traffic
C. Place all devices from the shoulder while facing away from traffic
D. Start with advance warning signs placed upstream and continue
installation toward the work area
D. Start with advance warning signs placed upstream and continue
installation toward the work area
Temporary traffic control installations should generally begin upstream
with advance warning signs and proceed downstream toward the activity
area. This sequence warns drivers before they encounter lane closures or
tapers and reduces the risk to workers performing setup operations.
3. During inspection of a temporary traffic control zone, a technician
discovers that drums used in the taper have shifted due to wind and
passing trucks, creating inconsistent lane guidance for motorists. What
is the most appropriate corrective measure?
A. Remove every other drum to reduce turbulence
B. Replace drums with cones regardless of roadway speed
C. Reposition and stabilize the drums to maintain proper taper alignment
D. Leave the drums as they are because drivers will adapt naturally
C. Reposition and stabilize the drums to maintain proper taper alignment
,Channelizing devices must remain properly aligned to provide consistent
visual guidance. Misaligned drums can confuse motorists and increase
crash risk. Repositioning and stabilizing the devices restores the integrity
and effectiveness of the taper.
4. A work crew performing utility repairs on a Maryland urban arterial
roadway must maintain pedestrian access through the work zone.
Which temporary traffic control measure best satisfies pedestrian
safety requirements?
A. Direct pedestrians into the active vehicle travel lane without protection
B. Close all sidewalks and provide no alternate route
C. Establish a clearly marked, accessible pedestrian pathway separated from
traffic and work activities
D. Require pedestrians to cross only at uncontrolled midblock locations
C. Establish a clearly marked, accessible pedestrian pathway separated
from traffic and work activities
Pedestrian accommodations are required in temporary traffic control
zones. Accessible pathways should be clearly identified, protected from
hazards, and compliant with accessibility standards to ensure safe travel
for all pedestrians, including those with disabilities.
5. A certified traffic control technician is evaluating whether a shadow
vehicle should be used during a mobile pavement marking operation
on a Maryland freeway. Which factor most strongly supports the need
for a shadow vehicle equipped with an impact attenuator?
A. Presence of low nighttime temperatures only
B. Increased exposure of workers to high-speed traffic conditions
C. Availability of additional lane width
D. Reduced visibility of pavement markings during daylight hours
B. Increased exposure of workers to high-speed traffic conditions
, Shadow vehicles with truck-mounted attenuators provide critical
protection for workers during mobile operations, especially on high-speed
roadways where errant vehicles pose significant impact risks. The
attenuator absorbs collision energy and protects personnel and
equipment.
6. While monitoring traffic flow through a temporary lane closure, a
technician notices frequent aggressive merging and sudden braking
near the taper. Which adjustment would most effectively improve
traffic operations and safety?
A. Shorten the taper below recommended length
B. Increase advance warning and provide earlier merge guidance
C. Remove lane closure signs to reduce driver distraction
D. Place all channelizing devices directly adjacent to each other
B. Increase advance warning and provide earlier merge guidance
Earlier warning and improved merge guidance help drivers make smoother
lane transitions with reduced conflict. Adequate taper length and timely
information improve traffic flow and decrease abrupt braking or
aggressive maneuvers.
7. A temporary traffic control plan requires a flagger operation on a two-
lane roadway with restricted sight distance due to a horizontal curve.
What is the most critical safety consideration for flagger placement?
A. Positioning the flagger where workers can easily communicate
B. Ensuring approaching drivers have sufficient stopping sight distance to
react to the flagger
C. Locating the flagger directly inside the work area
D. Placing the flagger immediately beyond the curve regardless of visibility
B. Ensuring approaching drivers have sufficient stopping sight distance to
react to the flagger
