The Washington State Patrol arrested a woman for DUI after the van she was driving ran off the road and rolled over.
The crash occurred in the 4800 block of Johnson Point Road.
Troopers believe the crash occurred at about 3:30 a.m. but it wasn't discovered until 7 a.m. They say it took daylight for a passerby to see the vehicle a distance off the roadway.
The 29-year-old driver was trapped in the driver's seat.
Trooper Guy Gill said the driver had only minor injuries.
"She's extremely lucky she wasn't seriously hurt or killed," he said.
Gill said speed and alcohol were factors in the crash.
