Two people were transported to the University of Maryland Shock Trauma Center early Saturday after the truck they were riding in overturned in Howard County, police said.
A 26-year-old Baltimore woman was partially ejected from the truck, and the driver, a 35-year-old Glen Burnie man, was also injured in the single-vehicle crash on Route 1 near Levering Avenue in Elkridge, Howard County police said.
The crash took place just before 2 a.m., when the 2006 Ford F-150 struck a guardrail and flipped, police said.
Police are investigating the cause. No charges have been filed in the wreck, and police believe that neither person in the truck was wearing a seat belt at the time of the crash.
No other vehicles were involved, police said.
The crash closed a section of Route 1 for about 4 hours Saturday.
