Road signs in Massachusetts are governed primarily by Chapter 85, Section 2 of the General Laws, which puts the Department of Transportation (MassDOT) in charge of every sign, marking, and signal on state highways, and requires all installations to follow the current Manual on Uniform Traffic Control Devices (MUTCD).1General Court of Massachusetts. Massachusetts General Laws Chapter 85 Section 2 – Traffic Signs or Devices; Erection and Maintenance; Rules and Regulations Outdoor advertising, electronic message boards, and municipal signage each carry their own layer of rules on top, and violations range from small statutory fines to escalating penalties for signs left in place after a conviction.
Who Controls Signs on State Highways
Chapter 85, Section 2 gives MassDOT authority to decide what signs, warning lights, traffic markings, and signal systems are needed for safety and convenience on state highways and connecting routes, and lets the department create, change, or rescind those regulations at any time.1General Court of Massachusetts. Massachusetts General Laws Chapter 85 Section 2 – Traffic Signs or Devices; Erection and Maintenance; Rules and Regulations
The statute also contains an exclusivity clause that catches many well-meaning parties off guard. No other authority may erect or maintain a sign on a state highway without MassDOT’s written approval covering the sign’s location, shape, size, and color. That approval lasts only as long as MassDOT permits, and the department can revoke it after notice.1General Court of Massachusetts. Massachusetts General Laws Chapter 85 Section 2 – Traffic Signs or Devices; Erection and Maintenance; Rules and Regulations Installing a sign on a state road without prior written approval is a statutory violation, regardless of intent.
Which MUTCD Edition Applies
Federal law requires every state to adopt the national MUTCD or maintain a manual that substantially conforms to it. The 11th Edition of the MUTCD, with Revision 1, became the national standard in December 2025.2Federal Highway Administration. MUTCD Current Edition States had until January 18, 2026 to adopt it or demonstrate substantial conformance.3Federal Highway Administration. Information by State
Massachusetts drew a clear line. All MassDOT projects advertised for construction after March 7, 2026 must follow the 11th Edition together with the state’s own amendments. Projects designed and advertised on or before that date can continue under the 10th Edition and the November 2022 Massachusetts amendments.4Mass.gov. Massachusetts Amendments to the 11th Edition of the Manual on Uniform Traffic Control Devices The 11th Edition places particular emphasis on provisions for vulnerable road users, including pedestrians, bicyclists, and accessibility.2Federal Highway Administration. MUTCD Current Edition
If your project is still in design and will go to bid after March 7, 2026, sign plans need to match the new edition. Plans referencing outdated standards get sent back.
Rules for Electronic and Digital Signs
Electronic message signs have their own regulation at 700 CMR 3.17. A permit is required, and the sign has to meet each of the following:5Legal Information Institute. Massachusetts Code of Massachusetts Regulations 700 CMR 3.17 – Requirements for Electronic Sign Permits
- Each static message stays on screen for at least ten seconds.
- Message changes happen instantly, not by scrolling or fading.
- The display does not move, appear to move, or change intensity during the static period. Time, date, and temperature readouts are the only exceptions.
- The sign dims automatically to match ambient light.
- Brightness does not exceed 0.3 foot-candles above ambient light, measured at a preset distance.
The regulation also bans sound, glare directed at the roadway, obstruction of official traffic signs, flashing or animated content, and more than one face visible from the same direction of travel.5Legal Information Institute. Massachusetts Code of Massachusetts Regulations 700 CMR 3.17 – Requirements for Electronic Sign Permits If MassDOT finds that a sign is causing glare or impairing driver vision, the permit holder has 24 hours to bring the intensity down.
Outdoor Advertising Permits
Outdoor advertising along Massachusetts roadways falls under Chapter 93 and is administered by MassDOT’s Office of Outdoor Advertising. On-premise signs advertising your own business at that business’s location generally do not need a state permit. Off-premise advertising requires both a license and a permit.6Mass.gov. Apply for a Licensed Outdoor Advertising Permit
Application fees vary by sign type. A non-electronic sign between 1 and 1,200 square feet costs $250 to apply for. An electronic sign permit application costs $1,000.6Mass.gov. Apply for a Licensed Outdoor Advertising Permit MassDOT recommends contacting the Office of Outdoor Advertising before submitting an application, given how many zoning, federal, and state requirements can derail one.
What Cities and Towns Can Do
Municipalities handle signs on the roads they control. Chapter 85, Section 2 lets cities and towns enact their own rules on signs, traffic signals, school zones, and markings without MassDOT approval, as long as those signs conform to the department’s current MUTCD and its sample regulation for a standard municipal traffic code.1General Court of Massachusetts. Massachusetts General Laws Chapter 85 Section 2 – Traffic Signs or Devices; Erection and Maintenance; Rules and Regulations That conformance requirement is the ceiling. A municipality cannot invent its own sign shapes, colors, or fonts, even for local streets.
Scenic and Historic Areas
Sensitive areas do not get relaxed rules. If anything, Massachusetts tightens them. Under MassDOT’s supplemental sign policy, new tourist attraction signs and business logo signs are not allowed on freeways east of the Cape Cod Canal when a District Highway Director finds the sign would harm the area’s scenic, historical, or environmental character.7Mass.gov. Supplemental Sign Policy Because it is a district-level determination, there is no single statewide list of restricted corridors, and applicants along historically or visually sensitive routes should expect added scrutiny.
Tourist information center signs are governed by the same policy, which requires placement that uses natural terrain, minimizes scenic impact, and avoids conflict with other highway signs.7Mass.gov. Supplemental Sign Policy
Fines and Liability
Penalties depend on which statute you violate. Under Chapter 85, Section 2, violations of MassDOT’s traffic movement regulations carry fines up to $20 per offense.1General Court of Massachusetts. Massachusetts General Laws Chapter 85 Section 2 – Traffic Signs or Devices; Erection and Maintenance; Rules and Regulations Related through-way violations under Chapter 89, Section 9 can reach $150 per offense.8General Court of Massachusetts. Massachusetts General Laws Chapter 89 Section 9
Outdoor advertising penalties are steeper and escalate. Chapter 93, Section 33 sets a fine of up to $100 for violating any outdoor advertising rule or regulation. If the offending sign stays up more than 20 days after a conviction, the fine rises to up to $500.9General Court of Massachusetts. Massachusetts General Laws Chapter 93 Section 33 The escalation is meant to force removal rather than treat fines as a cost of doing business.
Statutory fines are not the whole exposure. If a missing, improperly placed, or poorly maintained sign contributes to a crash, the municipality or contractor responsible can face civil claims for damages. Massachusetts courts have held public entities accountable in these situations, so sign compliance carries real liability weight beyond the ticket amount.
