Vision Zero Crash Records

Vision Zero Boston is our commitment to focus the city’s resources on proven strategies to eliminate fatal and serious traffic crashes in the city by 2030. We are inspired by the belief that even one fatality is too many. Learn more about about the Vision Zero Boston program at https://www.boston.gov/departments/transportation/vision-zero.

This dataset, provided as part of the Vision Zero Boston program, contains records of the date, time, location, and type of crash for incidents requiring public safety response which may involve injuries or fatalities. All records are compiled by the Department of Innovation and Technology from the City's Computer-Aided Dispatch (911) system and verified as having required a response from a public safety agency. To protect the privacy of individuals involved in these incidents, we do not indicate the severity of specific crashes or whether medical care was provided in any specific case.

Additional notes:

• Each incident is included only once regardless of the number of individuals involved.
• The date and time of an incident reflects when public safety response was dispatched to the location, not the crash itself.
• Records are updated on a monthly basis, at the end of the following month (for example, February data will be posted at the end of March).
• Records may be updated after their initial posting if new information becomes available.
• Motor Vehicle Accidents (MVAs) provided in this data set are Boston EMS incidents with a documented patient encounter that were identified as an MVA during the 9-1-1 call taking process, by crews on scene, or incidents where the injury cause is documented as related to an MVA. Roadway incidents determined to involve a pedestrian or bicycle are excluded, as they are captured separately in those data sets. Please note, in June of 2024, Boston EMS transitioned to a new patient record system. During this transition, a more refined approach to identifying roadway incidents was established, allowing for additional cases to be captured. Differences in MVA rates before and after June 2024 are reflective of this new reporting methodology and should not be interpreted as a change in motor vehicle incidents. Boston EMS is actively working to further improve this dataset. Once this process is complete, historic records will be updated to reflect the new methodology. If using this data for research, please reach out to Boston EMS directly at emailems@bostonems.org if you have any questions.
• Data is now available through August 31, 2026.
