CTC is proud to offer one-of-a-kind traffic signal cabinet training classes.
The two-day NEMA cabinet class covers the history, nomenclature, components, and features of traffic cabinets and dedicates a full day to hands-on troubleshooting. The ATC cabinet class has a similar format, but is consolidated into a single day.
Our Traffic Signal Cabinet Mobile Learning Lab is on tour and is likely coming to a city near you!

“With multiple systems installed across municipalities, traffic technicians can easily be confused and overwhelmed when trying to troubleshoot a traffic signal cabinet... but with the hands-on training and support at the CTC Mobile Learning Lab, I am now able to look in a cabinet and diagnose, isolate, and repair problems with confidence.”
