D. To allow workers to determine traffic procedures as conditions

Rationale: A traffic control plan establishes how motorists,

requirements, and protective measures needed to minimize conflicts
and hazards.
, 2. Which factor should receive the highest priority when establishing
temporary traffic control?
A. Contractor convenience
B. Equipment productivity

Rationale: Temporary traffic control must prioritize safety. Although
maintaining traffic flow and construction efficiency are important,
they cannot take precedence over protecting workers, motorists,
bicyclists, and pedestrians.
3. What is the primary function of a traffic control device?
A. To advertise the contractor's business
B. To communicate information, warnings, or regulatory requirements
to road users
C. To increase construction costs
D. To provide permanent roadway lighting
Rationale: Traffic control devices communicate information and
establish expectations for road users. Proper placement, visibility,
uniformity, and maintenance are essential for these devices to work
effectively.

unexpected roadway condition?
A. Guide sign
B. Regulatory sign

Rationale: Warning signs alert road users to conditions that may
require reduced speed, increased attention, or changes in vehicle
operation. Work-zone warning signs are especially important before
areas where traffic patterns change.

device becomes damaged?
A. Leave it until the end of the project
B. Move it to the contractor's storage area
C. Repair, replace, or otherwise correct it promptly
D. Cover it permanently
Rationale: Damaged or displaced devices can give motorists incorrect
information or fail to provide adequate protection. Contractors
responsible for traffic control should promptly restore devices to
proper condition.

temporary path?
A. Barricade tape only
B. Traffic cones or drums
C. Survey stakes
D. Sandbags alone
Rationale: Cones, drums, and other approved channelizing devices
guide vehicles through temporary traffic patterns. Their spacing,
visibility, and placement must be appropriate for the roadway and
operating conditions.
7. What is the purpose of a buffer space in a work zone?
A. To store construction materials
B. To provide parking for workers
C. To separate traffic from workers or a hazardous area
D. To provide a location for advertising signs
Rationale: A buffer space provides separation between moving traffic
and the work activity or hazard. It should not normally be used for
equipment, materials, vehicles, or personnel because its purpose is
protective separation.
