Branchville Ambulance 811B, along with units from Companies 12 and 14, were dispatched to Greenbelt Road (MD Rt 193) at Rhode Island Avenue around 4:30am for a reported motor vehicle accident with one vehicle overturned. Nothing was discovered at that location but the sight of police units moving west on Rt 193 suggested the incident was just East of Rt 1 on Rt 193 at 48th Avenue where Rt 193 takes a sharp right and is the site of frequent crashes. As C14A and A811B traveled west an overturned silver sedan was observed off the road just after 48th Avenue with Prince George’s County Police units already on scene. PGPD reported the vehicle was unoccupied. When A811B and C14A arrived they confirmed there were no patients and C14A placed units in service.
