A Maryland man was badly hurt Tuesday night when his car was struck head-on by a vehicle going the wrong way on Interstate 83 in Shrewsbury Township, police said.

Richard Doster, 54, of Freeland, suffered major injuries in the 8:34 p.m. crash, which happened near the Shrewsbury exit (Exit 4) of I-83, according to Trooper Rob Hicks, a state police spokesman.

A Ford Taurus driven by Neil Strein, 67, of New Freedom, was heading northbound in the southbound lanes when it crashed head-on into Doster's Buick LeSabre, Hicks said.

It appears Strein suffered a medical episode that caused him to go the wrong way on the interstate, according to Hicks, who said it's unclear how, or where, Strein got on I-83 the wrong way.

Doster was trapped inside his car, and fire and rescue crews had to forcibly remove parts of the LeSabre to get him out, Hicks said.

Strein suffered minor injuries; both he and Doster were taken to York Hospital, police said.

Doster was in serious condition Wednesday morning; Strein was in satisfactory condition, according to a York Hospital spokesman.

I-83 was closed until about 10 p.m.
