IMSA Bench Tech II study plan

IMSA Bench Tech II · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Traffic Signal & Signs and Markings

  • Map the four IMSA Bench Tech II domains onto a personal weakness list, ranking Traffic Signal and Signs and Markings first because each carries 25% weight.

  • Define signal phasing vocabulary (phase, interval, split, cycle length, offset, coordination) in your own words and self-quiz until you can define each from memory.

  • Sketch a four-leg intersection with left-turn lanes and label every signal head location, including supplementary near-side and far-side heads.

  • Identify the standard colors and shapes of regulatory, warning, and guide signs and state the meaning of each shape class without notes.

  • Build a spaced-repetition deck of at least 60 terms drawn from Domains 1 and 2.

Your checkpoint

A dated weakness tracker plus a 60-card deck covering signal phasing and sign-shape/color terminology.

Week 2

Traffic Signal

  • Trace a complete signal circuit from controller output through conflict monitor, load switch, and field wiring to the signal head.

  • Explain the function of the MMU (conflict monitor) and list at least five fault conditions it detects, such as conflicting greens and red failure.

  • Describe the difference between pre-timed, actuated, and semi-actuated control and give one field scenario that suits each.

  • Read a simple intersection timing chart and calculate splits and cycle length from given green, yellow, and all-red values.

  • Practice safe bench procedures for testing a signal head: verify power isolation, confirm lamp/bulb type, and document readings.

Your checkpoint

A one-page signal circuit diagram with the controller, MMU, load switches, and field terminals annotated in your own hand.

Week 3

Traffic Signal & Signs and Markings

  • Distinguish loop detectors, video detection, and radar detection by installation method, failure modes, and typical bench-test steps.

  • Explain pedestrian signal operation, including WALK, flashing DON'T WALK, and clearance interval timing relationships.

  • Identify the components of a signal head (housing, visor, backplate, lens, lamp or LED module, gasket) and state one inspection point for each.

  • Classify common pavement markings by function: longitudinal lines, transverse lines, symbols, and words, and state the color conventions for each.

  • Demonstrate how to verify LED signal module operation on the bench, including checking for dark segments and current draw.

Your checkpoint

A comparison table of three detection technologies with failure modes and bench-test steps, plus a marking color/shape reference sheet.

Week 4

Signs and Markings

  • Explain the relationship between sign retroreflectivity, sheeting type, and nighttime legibility, and describe how to inspect for degradation.

  • Identify mounting height, lateral offset, and post-breakaway requirements for common roadside signs.

  • Describe proper sign installation steps: post setting, sign attachment, plumb/level check, and torque or fastener verification.

  • Differentiate warning sign placement distance logic from regulatory sign placement logic using approach speed reasoning.

  • List at least eight sign inspection defects, such as fading, peeling, graffiti, bent posts, and obscured legends.

Your checkpoint

A 20-item sign inspection checklist you can carry on a job walk, with pass/fail criteria for each item.

Week 5

Roadway Lighting

  • Explain the purpose of roadway lighting: visibility for drivers, pedestrians, and workers, and reduction of night crash risk.

  • Compare luminaire types (HPS, LED, induction) by color rendering, warm-up behavior, efficacy, and maintenance profile.

  • Describe the anatomy of a lighting circuit: service point, photocell, contactor, breaker, ballast or driver, and luminaire.

  • Identify common roadway lighting standards concepts: luminance versus illuminance, uniformity ratio, and glare control.

  • Practice a safe lockout/tagout sequence for working on a lighting circuit and state the verification steps before touching conductors.

Your checkpoint

A labeled lighting circuit schematic plus a written lockout/tagout verification sequence.

Week 6

Roadway Lighting & Work Zone Temporary Traffic Control

  • Diagnose common luminaire faults (no light, cycling, dim output, flicker) and map each symptom to likely causes and test steps.

  • Explain photocell and time-clock control settings and how to verify correct dusk-to-dawn operation.

  • Describe the four components of a work zone: advance warning area, transition area, activity area, and termination area.

  • Select the correct taper length and channelizing device spacing for a given speed and lane closure scenario using formula reasoning.

  • Identify the roles of flagger, spotter, and traffic control supervisor and state the key safety duty of each.

Your checkpoint

A fault-diagnosis flow chart for roadway luminaires and a hand-drawn work zone layout for a one-lane closure.

Week 7

Work Zone Temporary Traffic Control

  • Explain how temporary traffic control devices differ from permanent devices in retroreflectivity, ballast, and portability requirements.

  • Describe proper placement and spacing of cones, drums, barricades, and arrow boards for a typical daytime lane closure.

  • State nighttime work zone requirements, including device retroreflectivity and lighting of the activity area.

  • Outline flagger signaling procedures and communication methods, including hand signals and radio protocol.

  • List at least six work zone inspection items, such as device condition, taper integrity, sign legibility, and worker PPE.

Your checkpoint

A work zone inspection form with at least 15 checkable items and a written nighttime setup adjustment list.

Week 8

Traffic Signal & Signs and Markings & Roadway Lighting & Work Zone Temporary Traffic Control

  • Complete a timed 60-question mixed-domain practice set and score each domain separately to identify remaining gaps.

  • Re-teach your two weakest topics from memory in writing, then correct errors against your notes.

  • Review all prior deliverables and rewrite any that contain errors or unclear steps.

  • Rehearse a bench-style scenario for each domain: signal head test, sign install, luminaire diagnosis, and work zone setup.

  • Finalize a one-page quick-reference sheet covering key formulas, color conventions, and safety sequences.

Your checkpoint

A scored 60-question practice result with a corrected error log and a one-page final quick-reference sheet.

Milestones

Week 2: Can draw the signal control chain from controller to signal head and explain conflict monitor faults without notes.

Week 4: Can classify any sign by shape, color, and function and apply mounting and placement rules to a field scenario.

Week 6: Can diagnose four common luminaire faults and lay out a compliant one-lane work zone from memory.

Week 8: Scores at least 80% overall on the mixed practice set, with no single domain below 70%.
