Five lanes of northbound Interstate 5 were blocked near the border of King and Pierce counties on Sunday morning after a driver caused a 5-car wreck then fled on foot, according to Washington State Patrol trooper Brooke Bova.
None of the injuries were believed to be life-threatening, Bova said.
“Seat belts save lives!” Bova tweeted with a photo of mangled vehicles whose driver suffered a head laceration.
A southbound driver struck a red 1998 Ford Ranger pickup which lost control, crossed all of the southbound lanes and the median and came to rest in the northbound lanes where it was hit by three other vehicles.

Four northbound lanes and one southbound lane were closed for more than four hours.
Authorities are looking for a black man who fled on foot after the wreck.
All lanes are now reopened, the state Department of Transportation announced via Twitter at 9:18 a.m.
