One person was killed and three children were injured after car crashed in Washington state, with one of the children climbing out of the wreck and flagging down help.

The car crashed about 50 feet off the road shortly before 11 a.m. Sunday and was found 15 feet down an embankment "with scattered rocks across the road of travel" by rescue crews in Kelso, a city about 130 miles south of Seattle, right by the Oregon border, Cowlitz 2 Fire & Rescue said.

Authorities said one of the children, age 7, was able to get out of the crashed car, climb up the embankment and seek help by flagging down a passing motorist, who alerted 911.
