Which MetroWest Massachusetts Towns Have the Highest Crash Rates?

MetroWest is where a Massachusetts crash is least likely to kill someone. Across 2022, 2023 and 2024 the eighteen communities counted here recorded 32,461 crashes and 45 of them were fatal, a rate of 1.39 per 1,000 against 2.68 for Massachusetts as a whole. That is roughly half the state rate, and the obvious explanation, that these are dense suburbs full of low-speed fender benders, does not survive testing: the 209 Massachusetts communities with three-year crash totals in the same range as these towns run 2.82 per 1,000, which is worse than the state, not better. Something specific to this region is producing crashes people walk away from. One number runs the other way and belongs in the same paragraph rather than buried later: bicycle involvement here is above the state rate, 11.95 per 1,000 against 10.75, and Needham of all places has the ninth highest bicycle crash share of any Massachusetts community with a thousand or more crashes.

Where the Numbers Come From

Everything here comes from MassDOT IMPACT Open Crash Data, the Commonwealth’s public record of crashes reported to the Registry of Motor Vehicles. Town totals cover 2022, 2023 and 2024 together, for all 349 Massachusetts communities. It is the same dataset behind every town page in the Massachusetts crash report.

For scale, those three years produced 405,245 crashes statewide, of which 1,087 were fatal, 92,759 involved an injury, 4,356 involved a bicycle and 5,980 involved a pedestrian. Those work out to 2.68 fatal per 1,000 crashes, an injury share of 22.89 per cent, 10.75 bicycle per 1,000 and 14.76 pedestrian per 1,000. Every regional figure below is measured against those four.

One caution belongs at the top rather than in a footnote. Crash records carry no traffic volume. A town with more crashes may simply have more cars moving through it, and nothing in this data separates a place that is more dangerous from a place that is busier. That is why this article reports rates rather than counts wherever it can, and why the central finding below is checked against towns of matched size instead of against the state alone.

The Eighteen Communities, and Why MetroWest Is Not a County

MetroWest is a regional convention rather than a line on an administrative map, so the honest thing to do is name what is being counted.

This article counts eighteen communities: Newton, Waltham, Framingham, Natick, Marlborough, Wellesley, Needham, Weston, Wayland, Sudbury, Lincoln, Ashland, Holliston, Hopkinton, Sherborn, Dover, Southborough and Hudson.

That set crosses two county lines, which is exactly why it is worth counting separately. Fourteen of the eighteen sit in Middlesex County. Wellesley, Needham and Dover sit in Norfolk County. Southborough sits in Worcester County. No county page describes this strip, because all three counties reach a long way past it into towns with completely different road types: the Middlesex County crash data covers everything from Cambridge to Townsend, the Norfolk County crash data reaches down to the Rhode Island line, and the Worcester County crash data covers half of central Massachusetts.

Four communities on the region’s southern edge were tested and left out: Franklin, Medway, Millis and Bellingham, which some definitions include and which sit closer to the Interstate 495 belt than to the Route 9 corridor. Adding them moves the region’s fatal rate from 1.39 to 1.50 per 1,000, which does not change the conclusion. Westborough and Northborough were also tested and left out as Worcester County towns rather than MetroWest ones; adding them moves the rate to 1.32. The finding is not sensitive to where the boundary is drawn, which is the only reason it is safe to quote a regional number at all.

The Central Finding, and the Objection to It

Taken together, the eighteen communities recorded 32,461 crashes, 45 of them fatal, 6,330 involving an injury, 388 involving a bicycle and 401 involving a pedestrian. That is 8.01 per cent of every crash in Massachusetts.

The fatality rate on that is 1.39 per 1,000, against 2.68 statewide. Roughly half.

A page that wanted a headline could stop there. It should not, because there is an obvious objection: these are mostly affluent, comparatively dense suburbs, and dense places produce large numbers of low-speed collisions in parking lots and at signalised intersections. Divide a small number of fatal crashes by a large number of trivial ones and any town looks safe. If that were the whole explanation, the finding would be a measurement artefact rather than a fact about MetroWest roads.

So it was tested. Every one of the 349 Massachusetts communities whose three-year crash total falls inside the same range as these eighteen towns, which is 248 crashes at the low end and 4,924 at the high end, was pulled out and counted as a group. There are 209 of them, they recorded 253,467 crashes, and 716 of those were fatal.

That is 2.82 fatal crashes per 1,000. Higher than the statewide 2.68, not lower.

Rate per 1,000 crashes	MetroWest, 18 towns	209 matched towns	Massachusetts
Fatal crashes	1.39	2.82	2.68
Bicycle crashes	11.95	10.87	10.75
Pedestrian crashes	12.35	11.91	14.76
Injury share	19.50%	22.39%	22.89%

Matching for size does not shrink the gap. It doubles it. Towns of the same crash volume elsewhere in Massachusetts are about twice as likely to record a fatal crash as these eighteen are.

The finding also survives removing the two biggest towns. Take Newton and Waltham out, and the remaining sixteen communities recorded 23,204 crashes with 35 fatal, a rate of 1.51 per 1,000. Still well under half the matched-band figure.

It is also the lowest figure of the five Massachusetts regions covered on this site, and the spread between them is wide.

Region	Crashes, 2022 to 2024	Fatal	Fatal per 1,000
MetroWest, 18 towns	32,461	45	1.39
Merrimack Valley, 24 towns	40,542	89	2.20
Cape Cod, Barnstable County	15,493	39	2.52
South Shore, 19 towns	28,028	79	2.82
Western Massachusetts, 3 counties	19,155	82	4.28
Massachusetts	405,245	1,087	2.68

A driver in Western Massachusetts is about three times as likely to be in a crash that kills someone as a driver in MetroWest, measured per crash rather than per mile. That is a statement about road type and speed, not about drivers.

Answer Capsule

MetroWest has the lowest fatal crash rate of the five Massachusetts regions measured on this site, ahead of the Merrimack Valley at 2.20 per 1,000, Cape Cod at 2.52, the South Shore at 2.82 and Western Massachusetts at 4.28: across 2022 to 2024 the eighteen communities of Newton, Waltham, Framingham, Natick, Marlborough, Wellesley, Needham, Weston, Wayland, Sudbury, Lincoln, Ashland, Holliston, Hopkinton, Sherborn, Dover, Southborough and Hudson recorded 32,461 crashes with 45 fatal, or 1.39 per 1,000, against 2.68 statewide and 2.82 for the 209 Massachusetts towns in the same crash-volume band, so matching for town size widens the gap rather than explaining it away. Injury share is also below the state figure, 19.50 per cent against 22.89. Three of the eighteen sit among the ten safest Massachusetts communities of a thousand crashes or more on this measure: Hudson recorded no fatal crash at all in three years across 1,245 crashes, Natick one in 1,997 and Wellesley one in 1,931. Two numbers cut the other way and are not minor. Bicycle involvement is above the state rate at 11.95 per 1,000 against 10.75, and Needham’s 20.70 per 1,000 is the ninth highest of any Massachusetts community with a thousand or more crashes. Newton records the region’s highest pedestrian rate at 24.37 per 1,000, well above the statewide 14.76, though not among the statewide worst, which is led by Brookline at 60.11. The region is not uniform: Dover’s rate of 8.06 per 1,000 rests on 2 fatal crashes out of 248 and should be read as a small-numbers artefact rather than a ranking. None of this bears on fault in an individual crash, which Massachusetts decides on the facts of the specific collision. This is general information about Massachusetts law and public crash data, not legal advice.

Sorted by fatal crashes per 1,000, most to least. The right-hand columns are what actually vary across the region.

Community	County	Crashes	Fatal	Fatal per 1,000	Injury share	Bicycle per 1,000	Pedestrian per 1,000
Dover	Norfolk	248	2	8.06	22.98%	12.10	0.00
Lincoln	Middlesex	308	1	3.25	30.52%	32.47	3.25

Weston	Middlesex	2,281	3	1.32	19.42%	3.07	1.32
Southborough	Worcester	1,068	1	0.94	20.41%	3.75	0.00
Marlborough	Middlesex	3,390	3	0.88	17.79%	7.96	7.37
Newton	Middlesex	4,924	4	0.81	19.33%	16.86	24.37
Wellesley	Norfolk	1,931	1	0.52	16.21%	12.43	8.80
Natick	Middlesex	1,997	1	0.50	15.92%	18.03	6.01
Hudson	Middlesex	1,245	0	0.00	21.53%	8.84	5.62

Read the top of that table with care. Dover’s 8.06 comes from 2 fatal crashes out of 248, Lincoln’s 3.25 from 1 out of 308, Sherborn’s 2.25 from 1 out of 445. At those volumes a single crash moves a town several places, and the honest description is that the small towns cannot be ranked against each other at all. The bottom of the table is much more solid, because it rests on thousands of crashes per town.

Three of the Safest Towns in Massachusetts Are in This Region

Take the 116 Massachusetts communities that recorded a thousand crashes or more over the three years, which is where the rates stop being noise, and rank them by fatal crashes per 1,000 from lowest.

Hudson comes third in the entire Commonwealth, with no fatal crash at all across 1,245 crashes; only five communities of that size recorded none over the three years, and Hudson is the only MetroWest town among them, alongside Westborough, Somerville, East Bridgewater and Dennis. Natick comes seventh at 0.50, one fatal crash in 1,997. Wellesley comes eighth at 0.52, one in 1,931. Newton is twelfth at 0.81, Marlborough fourteenth at 0.88 and Southborough seventeenth at 0.94.

Six of the eleven MetroWest towns big enough to appear on that list sit in the safest twenty. That is not a coincidence and it is not a statistical accident of the kind the matched-band test would have caught.

What it most likely reflects is road type. This region is built around signalised suburban arterials, commercial strips and town centres, with the two limited-access highways that cross it, the Massachusetts Turnpike and Interstate 95, carrying the high-speed traffic away from the surface network. High-speed undivided rural arterials, the road type that produces the worst fatality rates in Massachusetts, are largely absent here. The Route 20 corridor towns, which are exactly that road type, run 3.06 fatal per 1,000, more than twice MetroWest.

That is an inference from the pattern, not something the crash file states, and it is offered as an explanation to be tested rather than a finding.

The Two Numbers That Cut the Other Way

A regional page that only reported the flattering half of its own dataset would not be worth reading.

Bicycles. MetroWest records 11.95 bicycle crashes per 1,000, against 10.87 for the matched towns and 10.75 statewide. That is above both. It is also not a regional effect: take Newton and Waltham out and the remaining sixteen fall to 10.90, which is the matched-town figure almost exactly. The bicycle exposure sits in the inner core, and one town outside that core carries it too. Needham records 32 bicycle crashes on 1,546, or 20.70 per 1,000, which is the ninth highest share of any Massachusetts community with a thousand crashes or more, in a list otherwise made up of Cambridge, Somerville, Brookline, Arlington, Salem, Falmouth, Lexington and Dennis. Lincoln’s 32.47 is higher still but rests on 10 bicycle crashes out of 308.

Pedestrians in Newton. Newton records 120 pedestrian crashes on 4,924, or 24.37 per 1,000, against 14.76 statewide. It is the highest pedestrian rate in the region by a clear margin, and it sits alongside one of the region’s lowest fatality rates. Two things are worth saying about it precisely. It is well above the state figure. It is also not among the worst in Massachusetts, a list led by Brookline at 60.11 per 1,000, Salem at 51.28 and Cambridge at 46.08. Newton is a walkable city recording the crash profile of a walkable city.

Where a claim involves a bicycle or a person on foot, the applicable Massachusetts rules are set out in Massachusetts bicycle laws and pedestrian accident rights in Massachusetts.

What the Road-Level Data Shows, and What It Cannot

MassDOT also publishes each town’s highest-crash roads for the most recent year. Those are counts for 2024 alone, not rates, and each list stops at eight roads, so they describe hot spots rather than corridors.

In 2024 the busiest single entries in the region were Marlborough’s Boston Post Road East at 99 crashes, Wellesley’s Worcester Street at 89, Newton’s Washington Street westbound at 64 and eastbound at 50, Needham’s Highland Avenue at 54 and Natick’s Speen Street at 48.

Two limits apply to every road-level claim anyone makes from this file, and they apply here. MassDOT records the same physical road with and without its route number, so Natick’s Worcester Street appears both as “WORCESTER ST Rte” and as “WORCESTER ST Rte 9 E”, and totalling them would be a guess. And because each list stops at eight roads, a road that ranks ninth in a town does not appear at all. No corridor rate is computed in this article for that reason.

What This Does Not Mean for a Claim

A low regional fatality rate says nothing about any particular crash, and neither does a high one.

Fault in a Massachusetts collision is decided on the facts of the specific event: who had the right of way, what the speed was relative to conditions, what the physical evidence shows. Massachusetts also apportions fault between drivers under its comparative negligence rule, which is set out in comparative negligence and partial fault in Massachusetts. Town-level statistics have no evidentiary role in that. They are useful for understanding where and how crashes happen in a region, which is a different question from who is responsible for one of them.

Frequently Asked Questions

Q: Which MetroWest town in Massachusetts has the most car crashes?

A: Newton, with 4,924 crashes recorded across 2022 to 2024, which is 15 per cent of every crash in the eighteen communities counted here. Framingham is second at 4,359 and Waltham third at 4,333. Volume and danger are different things: Newton also has the fourth lowest fatality rate of the eighteen at 0.81 per 1,000, and Hudson, with a quarter of Newton’s crashes, recorded no fatal crash at all.

Q: Is MetroWest safer than the rest of Massachusetts?

A: On the fatality measure, clearly. The eighteen communities record 1.39 fatal crashes per 1,000 against 2.68 statewide, and the gap widens rather than narrows when the region is compared with the 209 Massachusetts towns of the same crash volume, which run 2.82. Injury share is also lower, 19.50 per cent against 22.89. Two measures run the other way: bicycle involvement is above the state rate at 11.95 per 1,000 against 10.75, and Newton’s pedestrian rate of 24.37 per 1,000 is well above the statewide 14.76.

Q: Why does Dover have such a high crash fatality rate?

A: It probably does not, and the number should not be read as a ranking. Dover’s 8.06 per 1,000 comes from 2 fatal crashes out of 248 total over three years. At that volume a single crash moves the rate by several points, which is why the small towns in this region cannot be meaningfully ranked against each other. The towns whose rates rest on thousands of crashes, such as Newton, Framingham, Waltham and Marlborough, are the ones worth comparing.

Q: Which towns count as MetroWest?

A: There is no official boundary. This article counts eighteen communities: Newton, Waltham, Framingham, Natick, Marlborough, Wellesley, Needham, Weston, Wayland, Sudbury, Lincoln, Ashland, Holliston, Hopkinton, Sherborn, Dover, Southborough and Hudson. Franklin, Medway, Millis and Bellingham are sometimes included and were left out as Interstate 495 belt towns; adding them moves the regional fatality rate from 1.39 to 1.50. Westborough and Northborough were left out as Worcester County towns; adding them moves it to 1.32. The conclusion does not depend on where the line is drawn.

Q: Does MetroWest have a bicycle crash problem?

A: The data says yes, and it is concentrated. The region records 11.95 bicycle crashes per 1,000 against 10.75 statewide, but remove Newton and Waltham and the remaining sixteen towns fall to 10.90, which is the level of comparable towns. The clearest single case is Needham, at 20.70 per 1,000, the ninth highest bicycle share of any Massachusetts community with a thousand crashes or more.

Q: Which road in MetroWest has the most crashes?

A: In the most recent year of the dataset, Boston Post Road East in Marlborough, with 99 crashes, followed by Worcester Street in Wellesley at 89 and Washington Street in Newton at 64 westbound and 50 eastbound. Those are counts for 2024 only. MassDOT records the same road both with and without its route number and publishes only each town’s eight busiest, so these identify hot spots rather than corridor totals, and no corridor rate is calculated here for that reason.

Q: Where does this crash data come from?

A: MassDOT IMPACT Open Crash Data, the Commonwealth’s public record of crashes reported to the Registry of Motor Vehicles, covering calendar years 2022, 2023 and 2024 for all 349 Massachusetts communities. It is the same dataset behind every town page in the crash report. Rates are fatal, bicycle or pedestrian crashes per 1,000 total crashes. The records carry no traffic volume, so they cannot separate a road or a town that is more dangerous from one that is busier.

Q: Does a low crash rate in my town hurt my injury claim?

A: No. Fault in a Massachusetts crash is decided on the facts of the specific collision, not on the record of the road or the town, and Massachusetts apportions fault between the drivers involved. Town-level data is useful for understanding where and how crashes happen. It has no evidentiary role in an individual claim, in either direction.

Q: Is Jimmy Knows AI giving me legal advice?

A: No. This is general legal and public-safety information about Massachusetts crash data, not legal advice, and reading it does not create an attorney-client relationship. For a specific crash, speak with a Massachusetts lawyer about your own facts. To discuss a situation, call Jim Glaser Law at (617) JIM-WINS. The line is answered 24 hours a day.

Talking to a Lawyer

The reason a region like this is worth writing about is not that its roads are unusually safe, although on the fatality measure they are. It is that the crashes here are a different kind of crash. A region whose fatality rate is half that of comparable Massachusetts towns, whose injury share is below the state figure, and whose bicycle involvement is above it, is a region of intersection collisions and vulnerable-road-user collisions rather than high-speed run-off-road ones. Those cases turn on different evidence: signal timing and sight lines rather than skid geometry, and often on a cyclist’s or a pedestrian’s account against a driver’s.
