Signals 101 is a foundational, student-friendly introduction to traffic signal technologies. It is designed to help new and future technicians build the baseline knowledge and confidence needed before enrolling in the IMSA Traffic Signal Technician I certification program.
Signals 101 covers similar topics at a slower pace, with deeper explanations, hands-on examples, and simplified terminology. The goal is to ensure students understand the “why” behind the work so they are better prepared to succeed in formal certification training and in early field assignments.
Signals 101 does not replace the IMSA Technician I program — it prepares students for it.
