(AP) — Authorities are looking for a driver whose vehicle hit a road worker on Interstate 80 near Lincoln.

Lancaster County Sheriff Terry Wagner says the road worker was hit Friday morning as he put up a traffic barrier near the Waverly exit. He was taken to a local hospital with serious but non-life-threatening injuries.

Witnesses say the driver took off after the accident.

Authorities are investigating whether the driver realized a person had been hit. But Wagner says the driver must know some sort of accident took place, since the crash knocked parts of the vehicle off and caused damage to its right front end.

Investigators are looking for a dark blue Toyota with a Nebraska license plate.
