The IMSA Bench Technician II credential sits within the family of certifications offered by the International Municipal Signal Association (IMSA), a professional association for public-safety and transportation infrastructure workers. IMSA states that 24,000+ professionals currently hold its certifications, and it lists five certification areas: Work Zone Temporary Traffic Control, Traffic Signal, Signs and Markings, Roadway Lighting, and Fiber Optics. The IMSA Bench Tech II study guide has 4 sections and about 1,684 words.
01Traffic Signal Equipment: Bench Verification and Fault Logic
The Traffic Signal domain of the Bench Technician II exam tests bench verification of signal control hardware - controllers, conflict monitors (MMUs), load switches, flashers, power supplies, and detectors - against NEMA TS 2 cabinet practice. Questions stress what a given test actually proves, which settings live on the monitor's program card, and how a fault is annunciated.

Signs and Markings covers MUTCD Parts 2 and 3 the way a field or shop technician applies them: color and shape coding, mounting height and lateral offset, retroreflectivity management, and the geometry of longitudinal pavement markings. White legend on red = regulatory (STOP, YIELD, DO NOT ENTER).
459 words, about 2 min03Roadway Lighting: Photometrics, Maintenance, and Electrical Checks
Roadway Lighting tests the photometric and electrical side of street lighting: how illuminance and luminance are specified, how maintenance and uniformity are handled, and how luminaires, photocontrols, and circuits are checked on the bench and in the field. Illuminance (footcandles or lux) is light arriving on the pavement; luminance (cd/m²) is light leaving it toward the driver.
