Maryland State Police arrested a 31-year-old Upper Marlboro man early Sunday morning after his Maserati struck two troopers and their marked patrol vehicles on northbound Branch Avenue near Allentown Road in Prince George’s County.
The suspect, identified as Avery Alexander Bost, faces charges of suspected impaired driving along with additional related traffic offenses. The incident occurred shortly before 1:30 a.m. on March 23, 2026, when troopers from the College Park Barrack responded to assist with a disabled vehicle in the left lane.
According to the preliminary investigation released by Maryland State Police, the first trooper’s marked patrol vehicle was parked behind the unoccupied disabled vehicle, with emergency lights activated. The second trooper’s marked patrol vehicle was positioned behind the first, also with lights on. Bost’s Maserati struck the rear of the second patrol vehicle, pushing it forward into the trooper standing outside his vehicle and then into the rear of the first patrol vehicle.
Both troopers sustained injuries and were transported by ambulance to a local hospital for treatment. Authorities confirmed they have since been released.
The College Park Barrack continues to lead the active investigation into the crash. No further details on the specific nature of the impairment or additional charges have been released at this time.
The crash highlights ongoing safety concerns for law enforcement personnel working roadside incidents in Prince George’s County, a busy corridor serving Southern Maryland commuters traveling between the Washington, D.C., area and communities in Charles, Calvert, and St. Mary’s counties. Branch Avenue, part of Maryland Route 5, sees heavy traffic and frequent roadside assistance calls.
Prince George’s County, adjacent to Southern Maryland jurisdictions, often experiences spillover traffic impacts from regional travel patterns. Incidents involving first responders underscore the risks faced by troopers during routine stops and the importance of driver awareness around emergency scenes.
Maryland State Police emphasized the need for motorists to slow down and move over when approaching vehicles with activated emergency lights, aligning with the state’s Move Over law designed to protect roadside workers.
Bost, a resident of Upper Marlboro in Prince George’s County, remains the focus of the ongoing probe. Court proceedings and any additional findings will be handled through the appropriate judicial channels in the county.
This event draws attention to impaired driving enforcement efforts across the region, where state police routinely target high-risk behaviors on major routes connecting Southern Maryland to the metropolitan area.
