TULSA - Tulsa police are working to find the driver who plowed into a pedestrian and drove away late Thursday.
It happened around 11 p.m. on Highway 169 near 41st Street.
Police told 2NEWS the man was trying to direct traffic around debris following a previous crash when he was struck.
The man was dragged about 150 yards.
He was in serious condition early Friday.
Officers are looking for a gray or silver SUV, possibly a Dodge Durango or Nissan Xterra.
The victim is described as a Hispanic male.
Officers say the man lived nearby and ran to help after hearing a previous crash on the highway.
Police say in that earlier accident, the driver of a red car who was believed to be drunk flipped his car and left the scene.
There was debris left on the roadway and the victim was trying to direct traffic when he was struck.
Tulsa Police Cpl. R.W. Solomon told 2NEWS it was a dangerous endeavor.
"It's hard even with the reflective gear we wear," Solomon said. "You still have the potential of getting hit. I'm not sure what type of clothing he had and there was a lot of traffic."
The man had surgery overnight and is expected to have more surgery Friday. Police say he is expected to survive.
The driver of the car that caused the first wreck, 28-year-old Adham Othman, was arrested for driving under the influence, driving without a license and the hit-and-run that he later caused.
Anyone with information on the driver should call Crime Stoppers at 918-596-COPS.
