BOSTON, Suffolk County, Mass., Sept. 30, 2026 — A woman suffered life-threatening injuries on Tuesday morning, September 29, when she was struck by a bicyclist near Boston University, according to Boston police. The collision happened around 9 a.m. at Commonwealth Ave and St. Mary's Street.
Police said the pedestrian was taken to a hospital in life-threatening condition. The bicyclist was also hospitalized, but with injuries that were not considered life-threatening.
A witness who was walking to class said she saw people gathered around the injured woman shortly after the crash, including a teaching assistant who is trained as an EMT and stopped to help. The witness said the woman appeared to be unconscious but was breathing, and that responders placed a neck brace on her before she was taken away.
Students in the area described the intersection as a spot where pedestrians, cyclists, and drivers often don't pay close attention to traffic signals. The crash remains under investigation, and no additional details have been released.
We wish those injured a full recovery.
How Investigators Piece Together a Pedestrian Bicycle Collision
Officers who respond to a crash like this one typically start by securing the scene, identifying witnesses, and documenting where people and vehicles ended up. That groundwork, measurements, photos, and sometimes a scan of the roadway, form the basis for any later reconstruction of who was where and how fast they were moving.
Medical updates often lag behind the initial report because hospitals release condition changes slowly, and police wait to confirm details with family before naming anyone publicly. A final determination on what led to a collision, including any citations, can take investigators several weeks, especially if it depends on interviews, camera footage, or a specialist's review of the roadway.
According to the National Highway Traffic Safety Administration, 24 percent of pedestrians killed in traffic crashes were struck by hit-and-run drivers in 2023. That figure reflects how often the person responsible leaves the scene, which is part of why agencies treat even minor-seeming pedestrian crashes as worth documenting in detail from the start.
Frequently Asked Questions
What kinds of injuries do pedestrians typically suffer in these collisions?
Common injuries include head trauma, fractures, and spinal injuries, since a pedestrian has no protection against the impact or the fall that follows.
What usually causes pedestrian crashes like this one?
Distraction, failure to yield at crosswalks or intersections, and jaywalking are frequently cited factors, along with cyclists or drivers not seeing pedestrians in time to stop.
Does speed matter if a cyclist or vehicle hits a pedestrian?
Yes. Lower speeds give more time to react and reduce the force of impact, which generally means a better chance of survival and less severe injury.
Where do most pedestrian accidents happen?
They cluster at intersections and crosswalks, particularly in dense urban areas with heavy foot traffic, where they mix with cyclists and turning vehicles.
What to Do After a Pedestrian Accident in Boston, MA
Anyone involved in or who witnesses a pedestrian collision should call 911 right away so responders can evaluate injuries on scene. Even if someone feels fine afterward, a medical check is worth doing, since some injuries, like concussions or internal bleeding, don't show symptoms immediately.
It helps to note the time, location, and any details about the people involved while they're fresh, and to get contact information for witnesses if it's safe to do so. Filing a police report, if one hasn't already been started, creates an official record that can matter later for insurance or medical follow-up. Boston University students and residents near campus can also reach out to campus safety resources for support after witnessing or being involved in a serious crash.
