The MBTA will activate cameras on buses starting Thursday, Oct. 1, to ticket drivers who block bus stops — and to send educational notices to those blocking bus lanes, with bus lane ticketing beginning Jan. 1. Brookline routes are slated for the next wave of enforcement in early 2027.

The program launches first on Silver Line routes SL4 and SL5 in Boston, running from Nubian Square through the South End and Chinatown to downtown. Cameras mounted inside bus windshields will automatically photograph license plates of vehicles in bus stops and lanes without any action from the driver, according to the MBTA's program page. A human reviewer will check every image before a ticket goes out.

Bus stop violations carry no warning. Drivers caught blocking a bus stop will receive a $100 ticket immediately, even during the Oct. 1 through Dec. 31 education period. The MBTA says blocking a stop forces riders into the street, creating safety and accessibility risks that justify skipping the grace period entirely.

Bus lane violations follow a different track. For bus lane offenses, the first violation triggers a warning with a lifetime lookback, even after fines begin Jan. 1. After that initial warning, fines escalate: $25 for the first ticketed offense, $50 for a second within 180 days, $100 for a third and $125 for a fourth or more. Commercial vehicles face different fines on a 365-day lookback window.

MBTA General Manager Phil Eng, who also serves as the state's interim secretary of transportation, framed the effort as behavioral. "This is not about fines; it's about changing culture," Eng told the MBTA Board of Directors on Sept. 24, as reported by WCVB. 

A February test of the camera technology flagged 26,500 potential violations, MBTA Director of Transit Priority Alex Hallowell told the board at the same meeting. Hallowell said peer transit agencies in other cities have seen 10% to 20% increases in bus speeds after adopting similar enforcement. About 36% of all MBTA riders use the bus, she said.

For Brookline, the expansion timeline matters most. Route 66, which runs along Beacon Street from Roxbury to Harvard through the heart of Brookline, ranked among the MBTA's 10 slowest and 10 most-bunched bus routes, according to a September Transit Matters report using October 2025 data. No route-by-route rollout schedule has been published for the expansion.

The MBTA said camera data is protected by state law and agency policy. The footage cannot be used for any purpose other than enforcing bus stop and bus lane violations, and a court order would be required for other access. License plate data and images are deleted 120 days after a case is resolved. Board member Peter Koutoujian, the Middlesex County sheriff, noted at the Sept. 24 meeting that the system does not connect to other automated license plate reader networks.

Tickets will be mailed to registered vehicle owners within 14 business days for Massachusetts plates and 21 days for out-of-state vehicles. Owners will have 60 days to appeal. Legal exceptions include entering a bus lane to make a nearby turn, pulling in or out of a parking space and stopping to make way for emergency vehicles.

The MBTA has not announced which Brookline-area routes will be added or a specific date for the early 2027 expansion.
