A car occupied by five teenage girls, ranging in age from 15 to 17, struck a power pole, trees and a fence and rolled onto its top along Highway 167 north of Puyallup early today.
Troopers said alcohol was a factor in the 3 a.m. accident, and the 17-year-old driver was arrested on the scene. She was treated at an area hospital for minor injuries.
One passenger suffered a broken arm, and the rest had bumps and bruises. All appeared to have been wearing seatbelts, which likely prevented more serious injuries, troopers said.
State Patrol Trooper Guy Gill said the driver faces charges of vehicular assault and drunken driving, and further investigation will determine whether she will be charged as an adult.
He said troopers are continuing the investigation into where the girls were going, how many of them had been drinking and how the alcohol was obtained.
