A motorcycle carrying two Weymouth residents collided with a car carrying a Quincy woman and two children just after 4 p.m. Saturday near the intersection of East Squantum and Ocean Streets, leaving five people injured, two of them with possible life-threatening injuries. Quincy Police say the 27-year-old male motorcycle operator and his 25-year-old female passenger, both from Weymouth, were taken to a Boston-area hospital in serious condition.
According to WCVB, the car was driven by a 43-year-old Quincy woman who had two children in the vehicle at the time of the crash. The car's occupants suffered only minor injuries and were also taken to a Boston-area hospital for evaluation. The cause of the crash remains under investigation, and it is not yet known whether either driver will face citations or charges.
Given the severity of the injuries reported by police, the motorcycle operator and passenger were likely routed to one of the region's Level 1 trauma centers, such as Boston Medical Center, Massachusetts General Hospital, or Tufts Medical Center, which handle the most serious crash injuries from communities south of Boston, per Boston Medical Center. Weymouth and Quincy sit next to each other on the South Shore, and the two communities see heavy daily crossover traffic for work, dining, and transit, according to Scalli Murphy Law.
A Corridor With a History of Trouble
East Squantum Street functions as a major two-lane coastal artery linking North Quincy and Hancock Street to the Squantum peninsula and Marina Bay, and it sees especially heavy traffic on summer weekends as visitors head to Wollaston Beach and Marina Bay, per TrafficVision.Live. The Boston Region Metropolitan Planning Organization has previously flagged intersections along the corridor as high-crash locations for both drivers and vulnerable road users, and the city has periodically pursued lane and signal upgrades there as a result. Quincy Police organize their patrol coverage into geographic sectors, with Sector B3 responsible for emergency calls, traffic enforcement, and crash investigations along East Squantum Street.
Motorcycle riders in Massachusetts are required under state law to wear DOT-approved helmets regardless of age or riding experience, a rule that can factor heavily into insurance and injury claims involving head trauma, according to Spada Law Group. It is not yet known whether the Weymouth riders were wearing compliant helmets at the time of the collision.
Part of a Troubling Statewide Trend
Saturday's crash arrives amid a documented rise in motorcycle deaths across Massachusetts even as overall traffic fatalities have declined. Fatal motorcycle crashes in the state climbed to 71 in 2024 and 65 in 2025, up from 54 in 2023, based on MassDOT crash portal data cited by Ballin Law. That same data shows roughly 70% of motorcycle collisions in Massachusetts happen at intersections or involve turning vehicles, a pattern consistent with the East Squantum and Ocean Streets crash site.
Meanwhile, preliminary National Highway Traffic Safety Administration figures published in April showed statewide traffic fatalities overall fell 3% to 352 in 2025, down from 363 the year before, according to Agency Checklists. Because Massachusetts follows a modified comparative negligence standard, injured parties can only recover damages if they are found 50% or less at fault for a crash, per Gavagan Law, meaning the results of the Quincy Police Department's crash reconstruction could carry significant weight for any future civil claims tied to Saturday's collision.
The crash adds to a string of serious traffic incidents Quincy emergency crews have handled in recent years, including a July 2025 multi-vehicle crash on Hancock Street near Billings Road that sent a car into a pizza shop and required a coordinated response from police, fire, and EMS. No further updates on the conditions of the motorcycle operator and passenger, or on potential charges stemming from Saturday's crash, have been released.
