New 25 MPH Speed Limit Goes Into Effect on January 9th

The default speed limit on City of Boston streets will be reduced from 30 miles per hour (mph) to 25 mph effective on Monday, January 9, 2017. If no sign is posted, 25 mph is the maximum speed limit on that street. Drivers are advised to watch for posted signs that indicate a modification to the speed limit, such as in School Zones where the speed limit may be lower than 25 mph. State owned roadways in the City of Boston will not be affected by this new law.

“Reducing the default speed limit will create safer roads for all, and I’m pleased our hard work and commitment to safer roads has created this new standard,” said Mayor Walsh.”This is an important milestone for Vision Zero, the City’s commitment to bringing the number of traffic-related deaths to zero. With our new 25 mph speed limit, we are one step closer to achieving our goal.”

“No one wants to be involved in a serious traffic crash and slowing down vehicles can help to keep us all safe from harm,” said Boston Transportation Commissioner Gina N. Fiandaca. “People who drive, walk and ride a bike in Boston are all asked to be aware of others sharing the roadway and to travel on our streets with caution.”

The speed limit is being reduced from 30 mph to improve safety for all users of Boston’s roadways. Studies show that the likelihood of a pedestrian suffering a fatal injury as a result of being struck by a motor vehicle decreases from 20 percent when the vehicle is traveling at 30 mph, to 12 percent when the vehicle is traveling at 25 mph. Slower speeds make it easier for drivers to stop when necessary. It also increases a driver’s field of vision making it more likely for the driver to see a pedestrian in the roadway.

The City of Boston is committed to providing local streets that are functional and safe for all users. New bicycle infrastructure, leading pedestrian intervals programmed into traffic signal timing, prominent pavement markings, speed radar boards, curb extensions, yield to pedestrian signs, and other traffic safety tools are all being used to meet this goal.

Reducing the default speed limit to 25 mph will help to keep resident and visitors from being involved in serious crashes in the City. Boston drivers are asked to travel responsibly and voluntarily comply with the speed limit to preserve the safety of Boston’s residents, daily commuters and visitors.

The implementation of the reduced default speed limit in Boston is a key accomplishment of the City of Boston’s Vision Zero agenda aimed at eliminating fatal and serious crashes in Boston by 2030. More information on Vision Zero may be found at

  1. “The city of Boston is committed to providing local streets that are functional and safe for all users”… Unless you live in the north end where commercial vehicles can park where they want (on side walks, infront of fire hydrants , in fire lanes or right in the middle of the street).

    ars we now all of a sudden going to see speed traps all over boston? Doesn’t seem like an effective use of our police force.

    How about we enforce the obvious first?

  2. Exactly. It’s a laughable change. All of the above cited by Ner plus the dozens of cars that blow through red lights well after the lights have turned red on a daily basis happen because they are allowed to and/or the penalty when they do happen to be enforced are too light and don’t hurt violators enough.

    1. This case is EXACTLY what is wrong with this ra ra changes that don’t address the real issues and what’s wrong with Btd enforcement.

      1) enforcement officer (right side of the photo WALKED RIGHT BY

      2) Person (I’ll avoid name calling) at BTD who closed out the case doesn’t even know the parking regulations ON THE BOOKS. This is extreamly common with the higher ups in enforcement

      3) linen truck that parks illegally on price st almost every day. At some point some offical, local politician or someone should call them up and say knock it off. Find a LEGAL spot and stop endangering RESIDENTS

      4) Again almost a daily problem and IF and that is a BIG IF, they get tagged, it’s the same fine- not progressive. They park there even when legal spots are available (though residents have to find legal spots ).

    1. Another day and another illegally parking job by metropolitan linen.

      The mayor’s office, the councilor’s office and BTD all know about this yet, not one has done something to address it.

      I just hope that a tragedy doesn’t occur because all of them are too busy to do their job and think a RESIDENT parked in street cleaning at 12:02 is a bigger problem compared to a private buisness located OUT SIDE OF THE CITY thumbing their nose at public safety is a bigger issue.

  3. Something seriously needs to be done about the speeding on Commercial Street. Going from 35 to 25 doesn’t help when cars are flying by at 40-50 miles an hour.

    1. Part of the problem on Commercial St and Atlantic Avenue is that everyone is playing “beat the light”. There are also, cab and bus pullover issues, plus if they can’t beat the light, just go through it fast. We could issue enough fines on that stretch to pay all of our property taxes.

      I know that some municipalities have cameras that trigger when someone runs the red. I know that some people try to refute the evidence. Not sure why that isn’t at least tried here? Also, the moving traffic violation goes onto your driving record which ultimately effects your insurance rates for the next 10 years. Normally the rate increase is worse than the court fines.

  4. It’s all about enforcement. And it’s always about enforcement. But it’s so much cheaper and easier to write new laws and pat each other on the back than actually enforce them consistently and try to make this a better place…

    1. It’s not cheaper as BTD enforcement could easily have somewhere here during the day, just hitting the hot spots and that person’s salary, benefits, etc would easily be covered under the current (and not effective) fine structure, but that of course assumes that enforcement would actually do their job.

      Also ever wonder if there are less fines for commercial vehicles illegally parking in the north end from Jan- April (when street cleaning is not in effect)… I can say that on non street cleaning days (when street cleaning is in effect) there are less (if any) enforcement officers…

  5. If the city really cared and/or felt it’s revenue enhancing, they’d start with simple things. Like enforcing Residential parking on the weekends and maybe controlling lunatic valets. The enforcement, however, is sporadic and inconsistent for most, if not all, traffic and parking issues in and around North End.
