Install Roundabout or School Zone Signs in Detroit
Introduction
Detroit, Michigan residents and property managers often need guidance to request new traffic controls such as roundabout signs or school zone signage. This guide explains how local traffic control decisions are made, which city office enforces sign installation and maintenance, what permits or requests you must submit, and practical steps to apply, report problems, or appeal decisions. It draws on official Detroit and Michigan traffic-control resources and provides links to the offices that handle signing requests and right-of-way permits. Follow these steps to begin a request and understand likely timelines, enforcement, and common issues.
Who Controls Signs in Detroit
The City of Detroit Traffic Engineering/Department of Public Works is the primary local office that manages traffic signs, markings and related right-of-way approvals. When a proposed sign affects a state trunkline or highway, Michigan Department of Transportation (MDOT) standards and approvals apply. Use the official city Traffic Engineering contact to start requests and verify jurisdiction. Traffic Engineering[1]
How the Process Typically Works
Requests usually follow these steps: investigation by Traffic Engineering, engineering study if needed, coordination with MDOT for state routes, design/specification of signs to MMUTCD standards, and installation by city crews or approved contractors. Expect a field study for complex changes such as a roundabout or new school zone.
- Submit a formal request or complaint to Detroit Traffic Engineering following the city form or web process.
- Traffic Engineering schedules an on-site review and/or engineering study.
- If approved, the city issues an installation order or a right-of-way permit for contractor work.
- Installation is completed by city crews or permitted contractors per approved specifications.
Penalties & Enforcement
Enforcement of sign placement, unauthorized removal, or alteration is handled by the City of Detroit through Traffic Engineering and related code enforcement divisions; some violations on state roads may involve MDOT. Exact penalties, fines and escalation schedules for unauthorized installation or removal of traffic control devices are not consolidated on the cited city pages and may be set by code sections or administrative rules; where specific figures are not published on the official pages we cite, the text below notes that they are "not specified on the cited page."

Applications & Forms
The city does not publish a single universal online form for sign installation on the Traffic Engineering landing page; some requests are submitted by email, online service request, or by completing right-of-way or permit applications when work in the public right-of-way is required. For design standards, follow the Michigan Manual on Uniform Traffic Control Devices (MMUTCD). MDOT and MMUTCD guidance[3]
- Right-of-way or street opening permits: check Detroit permitting pages or contact Traffic Engineering for the correct application.
- Submission: usually via the city online portal, email to Traffic Engineering, or in person at the appropriate city office.
- Fees: not specified on the cited pages; permit fees may apply depending on scope and whether city crews or contractors install signs.
How-To
- Document the need: gather location, photos, and reasons (safety, speed, pedestrian use) for a roundabout or school zone sign.
- Contact Detroit Traffic Engineering to submit your request or open a service ticket.
- Allow the city to conduct an on-site review and any required engineering or traffic studies.
- If approved, follow instructions to obtain any right-of-way permit and confirm installation schedule.
- Pay any required permit or installation fees and coordinate with city crews or an approved contractor for installation.
- If the request is denied, ask for the written reason and the appeal or review steps, then file an administrative review per the city's directions.
