How do I request a traffic signal study at a specific intersection?

MDOT SHA prepared an online brochure to provide a better understanding about what a traffic signal can do, what it cannot do, how traffic engineers can improve safety and reduce delays at an intersection, and what happens after we determine that a traffic signal is the best solution. Click here to view the brochure.

Complete an online Service Request form to submit your signal request. If you have additional questions, contact your MDOT SHA district office. Click here for a list of district offices.

Read the MDOT SHA online Speed Limits brochure, which can help you to understand speed limits, how they are set, and how they affect traffic and safety.

For questions about a speed limit on a specific road, contact your local district and ask for the traffic office.
