A large pig halted traffic on a Washington highway after escaping a truck headed for auction.

Washington State Trooper Rick Johnson shared a photo of the pig walking along I-5 in Federal Way on Saturday morning.

Johnson said the pig was loose on the highway until good samaritans and other troopers helped guide it to the shoulder of the road.

After about an hour, police reported the pig's owner realized the pig had escaped and returned to put it back in the trailer.

"So...the pig jumped out of his trailer on I-5 on the way to the auction," Johnson said. "Owner returned and put him back in trailer."

Johnson said the pig was OK following the escape, but was "not happy" to be back in the trailer.
