A car overturned down an embankment along the Beltway in Bethesda early Monday morning, trapping and seriously injuring the driver, a Montgomery County Fire & Rescue Service official said.

At about 2:20 a.m., the car rolled off the inner loop of the highway near the I-270 spur, spokesman Pete Piringer said.

The driver was trapped in the car for about 10 minutes. Rescue crews cut the roof off to get the driver out, Piringer said. Medics then took the driver to a local hospital with injuries that were serious but not life-threatening.

State police are investigating the cause of the single-car crash, he said.

MCFRS crews responded to other incidents Monday morning, including two pedestrians who were struck by cars—one at Second Avenue and 16th Street in Silver Spring at about 5 a.m. and another at Bradley Boulevard and Arlington Road in Bethesda at about 6:30 a.m.

Piringer said the pedestrians were taken to a hospital in both cases, though the injuries did not appear life-threatening. 

This story was corrected at 11:45 a.m. to correct the date of the crash. It occurred Monday, not Wednesday.
