Tigard police are looking for a driver who seriously injured a man on Highway 217 on Saturday.
Police say a 32-year-old Beaverton man was changing a flat tire in the shoulder of the onramp to northbound 217 from southbound Pacific Highway about 3 a.m., Saturday when a vehicle struck him and his car.
The driver did not stop, according to police spokesman Jim Wolf.
The man was found by a tow truck driver who had been dispatched to the flat tire minutes earlier.
The man was taken to OHSU. His name was not released and his condition is unknown.
Vehicle parts strewn in the area of the scene indicate the driver was driving a carbon-gray 1998-2002 Honda.
The suspect vehicle will have damage to the passenger side front fender and bumper.
