CTC is proud to offer one-of-a-kind traffic signal cabinet training classes. The two-day class covers the history, nomenclature, components, and features of traffic cabinets and dedicates a full day to hands-on troubleshooting. 

Our Traffic Signal Cabinet Mobile Learning Lab is on tour and is likely coming to a city near you! For information on our class schedule or to request a future class in your area, call 800-488-8841. Class size is limited!


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.
