IMSA Traffic Signal I study plan

Identify the required personal protective equipment for each common traffic signal work task and state the standard that governs it

Describe how to set up a lane closure and a shoulder work zone, including taper, buffer, and advance warning placement

Explain flagger hand signals and temporary traffic control device selection for daytime and nighttime work

List the steps for safely de-energizing and locking out a signal cabinet before work begins

Recognize electrical, fall, and struck-by hazards specific to pole and mast arm work and state the control for each

Diagram a complete signal head assembly, labeling visors, backplates, lenses, reflectors, and the mounting hardware

Compare span-wire, mast arm, and pole-mounted support systems and state when each is appropriate

Identify the wire and cable types used for signal circuits, loop leads, and power, including conductor color conventions

Explain grounding and surge protection requirements for signal poles and cabinets

Describe proper conductor termination, splicing, and weatherproofing techniques inside a signal head and cabinet

Calculate pole and foundation loading considerations from span length, signal head count, and wind load

Outline the steps for setting a pole, plumb and align it, and torque the anchor bolts to specification

Describe the procedure for installing and tensioning span wire and messenger cable

Explain how to pull cable through conduit and pole risers without exceeding bend radius or damaging insulation

Identify inspection points on a completed signal support and wiring installation that would fail a field review

Define the core terminology: phase, interval, cycle length, split, offset, coordination, and clearance interval

Distinguish MUTCD signal indications and their permitted, protected, and prohibited movements

Match signal head configurations to intersection geometry and lane assignments

Explain the difference between pre-timed and actuated operation and where each is used

Review weeks 1 through 3 material and close gaps on missed practice items

Describe how a controller moves through phases and intervals and how ring-and-barrier structure limits concurrent phases

Set and verify minimum green, passage time, yellow change, and all-red clearance intervals using standard formulas

Compare inductive loop, video, radar, and push-button detection and describe how each is wired into the controller

Explain actuated, semi-actuated, and coordinated operation and how offsets produce progression

Configure a simple two-phase actuated intersection on a controller or training simulator and verify it runs correctly

Describe the pre-energization inspection sequence for a new signal installation from foundation to cabinet

List the steps for functional testing of each phase, including conflict monitor and detection verification

Explain preventive maintenance tasks and their intervals for signal heads, cabinets, poles, and detection

Diagnose common faults such as a dark head, a stuck call, a flashing signal, or a conflict flash, and name the likely cause

Describe how to safely place a signal into flash mode and return it to normal operation

Demonstrate the use of a multimeter to check voltage, continuity, and loop resistance in a signal circuit

Outline the documentation required for inspections, maintenance logs, and repair records

Explain how to identify and correct a detection failure and how to verify a pedestrian push-button circuit

Describe safe response procedures for a knockdown, a flooded cabinet, or a signal on flash after a power event

Review weeks 4 through 6 material and close gaps on missed practice items

Re-take every missed practice item from weeks 1 through 7 and confirm the corrected reasoning

Summarize each domain's key facts on a single reference sheet for final review

Complete two full-length timed practice exams and review every wrong answer

Identify and drill the two weakest sub-topics across all five domains
