The Washington State Patrol says a truck driver whose tractor-trailer rig spun out on Interstate 90 and crashed over a highway barrier was left hanging over a steep embankment near Snoqualmie Pass near Lake Keechelus for more than an hour.

KOMO-TV reports the front half of the rig crashed over a jersey barrier on the eastbound shoulder of the highway. Trooper Darren Wright says the driver and truck cab were hanging over an embankment that dropped at least 40 feet.

Wright says emergency workers were able to free the driver in about an hour.

Trevor Wehrman, 22, was taken to Harborview Medical Center in Seattle following the crash, which was reported about 4 p.m. Thursday 11 miles west of Easton, according to the Washington State Patrol.

Trooper Wright said His injuries were not believed to be life-threatening. Troopers said Wehrman was driving too fast for conditions. It was snowing at the time, with snow on the ground.
