Problems With a Traffic Signal?

Maintenance on MassDOT signals is the responsibility of each District Office. If you would like to report a problem with an individual traffic signal, please use the Contact Us page. Please note that while MassDOT may be the largest single owner in Massachusetts, the majority of traffic signals in the Commonwealth are owned by municipalities, so we may need to direct you to the city or town with jurisdiction over the signal.
