Think you know the rules of the road and the ropes of the park? Massachusetts has a few surprises waiting in its legal code that catch visitors off guard. From crosswalk etiquette in Boston to beachside wildlife rules on the Cape, small missteps can lead to big headaches. Read on for a playful guide to the Bay State’s most commonly overlooked laws, so your trip stays fun, legal, and stress-free.
Whether you’re cruising through colonial towns or hiking in the Berkshires, knowing the quirks of local law can save you from an awkward encounter. Some rules are rooted in history, others in environmental protection, but all are enforced with surprising consistency.
So before you pack your sunscreen or lace up your walking shoes, take a moment to learn what not to do in Massachusetts.
1. Crosswalks and Jaywalking in Boston

In Boston, pedestrians are expected to follow crosswalk signals and yield rules, and violations can be ticketed under Massachusetts General Laws Chapter 90, Section 18A and related city ordinances. While locals often cross assertively, the law still requires pedestrians to obey traffic control devices and not dart into the street when it is unsafe.
Tourists sometimes assume jaywalking is rarely enforced, but officers do issue citations during safety blitzes near major intersections like Downtown Crossing and near Fenway on game days. The safest move is to wait for the walk signal, cross within the marked lines, and make eye contact with drivers. Boston drivers are alert but fast, so predictable behavior matters for everyone’s safety.
If you are in the Back Bay or around Government Center, look for countdown timers and use them. The city’s Vision Zero approach prioritizes pedestrian safety and expects compliance. Enjoy strolling the Freedom Trail, but remember that careful, lawful crossings keep you moving without a ticket or a scare.
2. Leash Laws in Public Parks

Leash rules are widespread across Massachusetts, and tourists often overlook them during scenic strolls. State parks managed by the Department of Conservation and Recreation generally require dogs to be leashed unless in designated areas, and many municipalities adopt stricter standards.
Boston’s municipal code, for example, requires dogs to be leashed in public spaces and properly licensed; Animal Care and Control enforces fines for violations. Cambridge and Somerville also enforce leashes in most parks, including along popular paths like the Charles River esplanade areas. Even friendly, well-trained dogs can startle cyclists or wildlife, so rangers and officers take compliance seriously. Check posted signs at park entrances and trailheads, since rules can vary by location and season.
Bring waste bags and dispose of them in bins, since littering carries separate penalties. A simple six-foot leash keeps you legal and courteous. Your pup can still enjoy the views and fresh air, and you will avoid an avoidable fine and a lecture from a ranger.
3. Feeding Wildlife Is Prohibited

Feeding wild animals is generally prohibited in Massachusetts because it alters natural behavior and can spread disease. The Massachusetts Division of Fisheries and Wildlife strongly advises against feeding any wildlife, and many towns have ordinances expressly banning it.
In coastal areas and on the Cape, feeding gulls is a classic mistake that leads to aggressive swarms and nuisance issues. Boston and Brookline post signs warning against feeding pigeons and other birds in public squares. Black bears in western Massachusetts are another concern; feeding them, even unintentionally through unsecured trash or bird feeders, can be considered illegal baiting under 321 CMR regulations and can lead to dangerous encounters.
Fines vary by municipality, but rangers and animal control officers routinely educate and cite repeat offenders. If you want animal encounters, stick to designated wildlife viewing areas and bring binoculars. Secure your trash, skip the bread at the pond, and keep snacks to yourself. You will protect animals and avoid a ticket while keeping everyone safe.
4. Bikes Must Obey Traffic Rules

Massachusetts cyclists have the right to use most roads, and they must follow the same traffic rules as drivers. Under MGL c.85, s.11B, cyclists must stop at red lights and stop signs, yield to pedestrians in crosswalks, and use lights at night.
Tourists renting bikes along the Charles or on the Minuteman Bikeway sometimes roll through signals or ride against traffic, which can result in citations. At night, a white front light and red rear light or reflector are required, and the law requires an audible signal, such as a bell or voice, when passing. Helmets are required for riders 16 and under, though they are wise for everyone. Ride single file when traffic is heavy, and use hand signals when turning.
Many cities, including Cambridge and Somerville, have dedicated lanes and clear signage that make compliance easy. Follow the rules and you will enjoy a smooth ride while staying safe and legal through historic neighborhoods and river views.
5. Parking Rules on Street Cleaning Days

Street cleaning restrictions in Massachusetts cities, especially Boston and Cambridge, catch visitors by surprise. Signs on each block list cleaning schedules, and parking during those hours can result in tickets or towing. Boston’s Public Works and Transportation Departments publish seasonal calendars by neighborhood, and enforcement is consistent from spring through fall.
Even if the street looks clean, the rule still applies. In Cambridge, posted signs indicate alternating side schedules, and the tow trucks arrive right on time. If you are using a hotel or short-term rental, ask for the exact schedule for nearby blocks, then set a phone reminder. During snow emergencies, separate rules apply for snow routes, but cleaning rules resume once declared over.
Always read the entire sign, including small print about holidays. A quick check can save you a long detour to the tow lot and unexpected fees. Consider garages or apps that show real-time restrictions to keep your visit hassle-free.
6. Hands-Free Device Law for Drivers

Massachusetts adopted a hands-free driving law under MGL c.90, s.13B, which prohibits holding a mobile device while operating a vehicle. Tourists relying on navigation sometimes pick up phones at red lights, not realizing that holding the device is still illegal unless it is a single tap or swipe in a mount.
First offenses carry fines, and repeated offenses add insurance surcharges and mandatory education. Voice commands, dashboard mounts, or passenger assistance keep you compliant. The law applies statewide, including on scenic routes to Cape Ann, in the Berkshires, and through downtown Boston’s tunnels. Drivers under 18 face stricter rules and penalties.
If you need to input an address, pull over to a safe, legal spot before touching the screen. Police conduct periodic enforcement waves, especially near busy corridors like the Mass Pike and Route 93. Keep your eyes on the road and your hands off the phone so your trip stays smooth and safe.
7. No Drones in Certain Parks and Historic Sites

Unmanned aircraft rules can be surprisingly strict around Massachusetts parks and historic sites. The National Park Service prohibits drone launch and landing in places like the Boston National Historical Park without special permits.
The Massachusetts DCR has site-specific restrictions, and many municipalities bar drones over playgrounds and crowded beaches for safety and privacy. Logan Airport’s controlled airspace further complicates matters near Boston, and the FAA requires recreational flyers to follow the TRUST test, registration, and LAANC approvals where applicable. Tourists who launch from a green patch near the harbor may unknowingly violate both local ordinances and FAA rules.
Always check sectional maps and park websites before you fly. Keep your drone in visual line of sight, avoid crowds, and respect wildlife buffers. If in doubt, leave it packed and take photos from the ground. You will protect people, historic landmarks, and your wallet from fines and confiscation.
8. Beach Rules: Dunes and Protected Areas

Massachusetts beaches have sensitive dunes and protected bird nesting zones that are off-limits to foot traffic. On Cape Cod, shorebird protections for species like piping plovers and least terns can close sections of beach or restrict pets during breeding season under state and federal guidelines. DCR and local conservation commissions mark these areas with rope fencing and signs.
Tourists sometimes step over for a better photo, which can damage vegetation and disturb nests, leading to fines. Stay on boardwalks and designated paths to preserve fragile dune grass that anchors the shoreline. Lifeguards and rangers will direct you to open stretches if closures change. Off-road vehicle permits are suspended on some beaches during nesting, so check town websites before you go.
Respecting these zones ensures thriving wildlife and safer beaches for everyone. Your footprints belong on wet sand, not in the dunes.
9. Helmet and Personal Mobility Devices

Electric scooters and personal mobility devices appear in various Massachusetts cities as pilot programs or private rentals. Rules vary, but the state treats e-scooters similarly to bicycles for many purposes, while prohibiting operation on sidewalks in many downtown areas under local ordinances.
Helmets are mandatory for scooter operators under 16, and advisable for all riders. Cambridge and Brookline have clear signage indicating where riding is allowed and where you must dismount. Night riding requires lights, and traffic signals must be obeyed. Tourists sometimes cruise on crowded sidewalks near Harvard Square or Faneuil Hall, which can earn warnings or fines.
Check city websites for current pilot rules, since programs change. Park devices responsibly to avoid blocking curb ramps and doorways, which is enforceable under local codes. A cautious approach keeps pedestrians safe and your sightseeing smooth.
10. Quiet Hours and Noise Ordinances

Many Massachusetts municipalities enforce quiet hours, commonly late evening to early morning, to preserve neighborhood peace. Boston’s noise ordinance addresses excessive sound levels, and Cambridge uses specific decibel thresholds with enforcement by police or inspectional services.
Travelers staying in short-term rentals sometimes trigger complaints with late-night music or loud conversations on balconies. Even lively conversations can carry across brick courtyards and narrow streets. Check the posted house rules and local ordinances, and close windows if you are chatting late. Portable speakers are a frequent culprit, and fines can escalate for continued violations. Construction noise also has regulated hours, which may explain early morning clatter in some districts.
Respecting quiet hours will keep neighbors friendly and hosts happy, and it preserves the charm of historic neighborhoods. When in doubt, keep volumes low after 10 p.m. and move gatherings indoors with windows closed.
11. MBTA Rules: Fares, Bikes, and Priority Seating

The MBTA has clear rules for riders on subways, buses, and commuter rail. Paying the correct fare, respecting priority seating for seniors and riders with disabilities, and following bike policies are essential. Bikes are allowed on certain subway lines during off-peak hours and on many commuter rail trains, but not during crush periods or special events.
Folding bikes are generally allowed at all times if folded. Eating is discouraged on vehicles and platforms, and open containers of messy food can attract attention from staff. Keep bags and suitcases clear of doors and aisles, and do not block emergency intercoms. Fare inspectors and transit police conduct spot checks on the Green Line and commuter rail.
Tourists unfamiliar with rear-door bus boarding or proof-of-payment zones should read posted signs. Following these rules keeps service running smoothly and your travels pleasant.
12. Littering and Carry In/Carry Out

Littering is illegal statewide, and many Massachusetts parks operate on a carry-in/carry-out policy. Tourists often assume there will be bins everywhere, but trailheads in the Berkshires, Mount Greylock, and some Cape Cod beaches may have limited receptacles.
Leaving trash, including fruit peels and nut shells, can draw wildlife and is subject to fines under local ordinances. Keep a small bag for your waste and pack it out to the nearest proper bin. Cigarette butts and gum are common violations and are treated as litter. Rangers routinely remind visitors to secure food wrappers from wind on open beaches.
Clean sites make for better photos and safer habitats. Plan ahead, bring minimal packaging, and dispose of waste responsibly so the next traveler enjoys the same pristine view.
