Boston Is the Most Dangerous City for Drivers in the U.S.

Boston was ranked first in the top 10 most collision-prone U.S. cities in Allstate’s 2025 report. Sadly, this is not a new problem, as the city also held this ranking in 2015. In fact, Massachusetts as a whole recorded 343 road deaths in 2023, with someone dying on a state road nearly every day.

This ongoing problem is due to several risk factors, such as dense urban layouts, high pedestrian and cyclist traffic, speeding and distracted driving, and roads built decades ago without current safety standards.

Boston’s High-Crash Intersections: The Latest Car Accident Data

This section examines the intersections in Boston with the highest documented crash rates, based on Vision Zero data.

Massachusetts Avenue and Melnea Cass Boulevard

The intersection of Massachusetts Avenue and Melnea Cass Boulevard is the single most dangerous crossroad in Boston, with Vision Zero recording six crashes in 2023 alone. Over half of these incidents involved a pedestrian or bicyclist.

Residents commonly refer to this intersection as Mass and Cass. Due to its proximity to Boston Medical Center, the area experiences constant pedestrian, ambulance, and heavy-truck traffic converging at a single wide, chaotic junction. Similarly, large semi-trucks heading to Newmarket Square for pickups and deliveries pose a unique danger to pedestrians.

Albany Street and Massachusetts Avenue

Albany Street and Massachusetts Avenue are counted as the second-worst crash hotspot in the South End. This intersection recorded four crashes in the same year.

This intersection is also located near Boston Medical Center, which contributes to high pedestrian activity in the area, as the hospital generates significant foot traffic from patients, staff, and visitors. In addition, the intersection’s complex layout creates confusion for drivers and limited visibility, further elevating crash risk.

Harvard Street and Morton Street in Dorchester

Harvard Street and Morton Street had two collisions in 2023. Dorchester is one of Boston’s most densely populated neighborhoods, meaning more people on foot at all hours. As a result, this major intersection is a high-volume residential and commercial corridor where congestion builds throughout the day.

Cedar Street and Columbus Avenue in Roxbury

Cedar Street and Columbus Avenue is a highly congested intersection in Roxbury with three crashes recorded in 2023.

A major contributor to the area’s heavy traffic is its proximity to a busy MBTA transit hub and Roxbury Community College, which generates steady pedestrian and bicyclist flow from students and daily commuters.

At the same time, the surrounding street design prioritizes vehicle throughput, with wide multi-lane roadways and fast-moving traffic that limit safe crossing opportunities and reduce overall pedestrian protection.

Boston's Most Dangerous Roads and Highways for High Speed Accidents

Along with Boston’s many congested and dangerous intersections, the city also records numerous accidents on full corridors and highways.

I-93 and the Mass Pike

I-93 and the Massachusetts Turnpike (I-90) are the two busiest highways in the Boston region, consistently dealing with high-speed, multi-vehicle crashes. Drivers on these roads must navigate sudden merges, lane changes, and heavy commercial truck traffic, which often create dangerous conditions, especially during peak commute hours.

Storrow Drive and Soldiers Field Road

Storrow Drive and Soldiers Field Road run along the Charles River and are known for speeding, limited sightlines, and recurring “Storrowing” incidents, where overheight vehicles strike low-clearance bridges. These roadways were not designed to accommodate modern traffic volumes and function primarily as high-speed through routes, leaving limited infrastructure or safe crossing options for pedestrians along the corridor.

Arborway and Centre Street

StreetsBlog Massachusetts consistently flags Arborway and Centre Street as high-risk speeding corridors. Centre Street, in particular, runs through Jamaica Plain and West Roxbury. These areas are filled with active pedestrian and cyclist traffic, making speed-related crashes especially dangerous.

When To Call a Boston Car Accident Lawyer After a Crash at a Dangerous Intersection

Boston drivers should always do their part to drive safely and defensively. Unfortunately, even the most careful drivers can be injured by another person’s negligence.

Being injured at an intersection or on a roadway with a documented crash history may be relevant to a personal injury claim. Prior collision data can help show that a location had known safety concerns, but an injured person must still prove liability, causation, and damages under Massachusetts law. 

In many cases, individuals do not initially realize they may have a claim, especially when they assume the crash was simply bad luck at a busy or confusing intersection rather than the result of a preventable safety issue.

By partnering with a seasoned lawyer who is familiar with the Boston legal landscape, you can benefit from local knowledge and experience.
