Temporary Traffic Control Fundamentals and Standards
Diagram the four component parts of a temporary traffic control zone (advance warning, transition, activity area, termination area) and mark where each begins and ends for a typical lane closure.
Distinguish the duration categories of work (long-term stationary through mobile) and match each category to at least two device-placement expectations.
Compute taper lengths and longitudinal buffer distances from posted speed and lane width using the standard relationships, working the math by hand.
Explain how federal, state, and agency-level requirements stack on one another and identify which governs when a local practice conflicts with a higher standard.
Your checkpoint
A single-page reference sheet containing your hand-drawn four-part zone diagram, taper calculations worked for 25, 35, 45, and 55 mph, and a short note on which standard controls in a conflict, self-quizzed to 90% recall.
Temporary Traffic Control Fundamentals and Standards & Traffic Control Devices and Materials
Classify each major device family (signs, channelizing devices, barricades, arrow boards, warning lights) by permitted use, minimum size, and retroreflective sheeting requirement.
Select and justify advance warning sign spacing for urban, rural, and higher-speed conditions across at least six practice scenarios.
Verify mounting height above the roadway and lateral offset from the edge of the traveled way for ten sample layouts, flagging every out-of-tolerance placement.
Determine when positive protection must replace channelizing devices, and state the reasoning in one sentence per case.
Your checkpoint
A device-selection decision table covering twelve common field situations, each row listing chosen device, spacing, height, and the standard-based reason for the choice.
Temporary Traffic Control Fundamentals and Standards & Traffic Control Devices and Materials
Compare drums, cones, tubular markers, and barricades on stability, ballast needs, and nighttime visibility, then rank them for three different exposure conditions.
Specify temporary pavement marking and delineation requirements for a closure expected to remain in place for several weeks.
Describe correct arrow board placement distance and operating mode for lane closures, shoulder closures, and mobile operations.
Diagnose ten faulty device setups (wrong height, insufficient ballast, damaged or faded sheeting, wrong sign orientation) and state the specific correction for each.
Your checkpoint
A 20-item field inspection card listing pass/fail criteria for the devices you are most likely to encounter, formatted to be carried and used on site.
Traffic Control Devices and Materials & Work Zone Layout, Setup, and Maintenance
Assemble a complete lane-closure layout from advance warning through termination for a four-lane urban arterial with a posted speed of your choice.
Calculate work space, buffer space, and lateral clearance for a given shoulder width, lane width, and traffic condition.
Design a temporary accessible pedestrian route around a sidewalk closure, including barrier placement and detectable warning considerations.
Convert a daytime layout into a nighttime layout by adding lighting, upgrading retroreflective devices, and relocating flagger stations as needed.
Your checkpoint
Two scaled layout sketches (day and night) of the same arterial closure with every dimension, device, and spacing labeled, checked against a 15-point self-verification list.
Work Zone Layout, Setup, and Maintenance
Contrast layout requirements for shoulder work, short-duration work, and moving or mobile operations, noting where standard taper and buffer rules do not apply.
Plan flagger station placement, sight distance, and taper requirements for a two-lane, two-way road operating under alternating one-way traffic.
Lay out a work zone through or adjacent to an intersection while preserving turn lanes and signal timing assumptions.
Sequence device installation and removal in the correct order for three scenarios and explain why the order matters for each.
Your checkpoint
A written step-by-step setup and takedown sequence for three scenarios, each with a full device list and numbered order of operations.
Work Zone Layout, Setup, and Maintenance & Worker and Roadway User Safety, Inspection, and Documentation
Build a daily and periodic inspection schedule for an active work zone and list the changes that trigger an immediate re-check.
Detect layout drift during a self-audit of a simulated zone (displaced devices, missing signs, outdated messages, worn markings) and prescribe corrections.
Document an inspection using standard record fields: date, reviewer, location, device condition, deficiency, corrective action, responsible party, close-out date.
Rank observed deficiencies by risk by weighing worker exposure and road user exposure separately, then justify the top three rankings.
Your checkpoint
A completed mock inspection report documenting at least eight deficiencies with risk ranking and corrective actions, plus a one-week follow-up plan.
Worker and Roadway User Safety, Inspection, and Documentation
Specify required high-visibility apparel and personal protective equipment for each work zone role and for day versus night conditions.
Design an internal traffic control plan that keeps construction vehicles, equipment swing areas, and worker foot traffic from conflicting.
Explain escape path, drop-off, backing, and struck-by hazard controls in plain language suitable for a new crew member's first day.
Summarize what a traffic control plan submittal contains and who reviews it, and identify the pieces you would need to produce yourself.
Your checkpoint
A one-page crew safety briefing script plus a 10-question worker and road user safety self-test with answer key and cited reasoning.
Temporary Traffic Control Fundamentals and Standards & Traffic Control Devices and Materials & Work Zone Layout, Setup, and Maintenance & Worker and Roadway User Safety, Inspection, and Documentation
Re-derive from memory the taper, buffer, and sign-spacing relationships and the key dimension tables without notes.
Complete two full-length timed practice sets and log every miss by domain and by error type (misread, unknown fact, calculation, judgment).
Re-teach your three weakest sub-topics in writing to confirm you can explain them without prompting.
Compress the highest-risk facts from all four domains into one page you can review in ten minutes before the exam.
Your checkpoint
A scored practice-exam log with error analysis plus a final one-page memory aid, targeting 85% or better on the second timed set.
Milestones
Week 2: Closed-book self-quiz on domain 1 (structure, duration categories, taper and buffer math, standards hierarchy) at 80% or better, and the four-part zone diagram redrawn correctly from memory.
Week 4: Both day and night layout sketches pass all 15 dimension and device checks with no unresolved errors, and a closed-book quiz covering domains 1 and 2 scores 80% or higher.
Week 6: Mock inspection report is complete enough that a second person could correct every listed deficiency using only what you wrote, and setup/takedown sequences are recalled from memory.
Week 8: Second timed practice set scores 85% or higher with no domain below 75%, and every logged error has a written correction tied to a specific standard.
