Christopher Klinefelter, of the first block of Bosley Lane, was traveling south on Garrison Forest Road near Nancy Ellen Way in a 2006 GMC Sierra about 2:40 a.m. when he failed to negotiate a curve in the road and the vehicle went into a grassy area on the northbound side of the road, police said.
The vehicle then struck a retaining wall and went airborne as it traveled, flipping in the air, back onto the road, police said.
Klinefelter was ejected from the vehicle during the crash, police said.
He was transported to Northwest Hospital, where he was pronounced dead, police said. No other vehicles were involved, and Klinefelter had no passengers, police said.
The crash is being investigated by the Baltimore County crash team.
