(IMSA) Certified Traffic Signal Technician (CTST) Traffic signal controllers operate on multiple communication protocols—some candidates struggle because they haven’t worked with NEMA TS 2 or 404 standards beforehand. The CTST assumes foundational knowledge of electrical systems, field timing coordination, and detection equipment. Without hands-on experience troubleshooting interconnected signals, you’ll find the fault-diagnosis section particularly demanding. Practical background matters significantly here.
