A Pepsi truck jackknifed and slid into Mores Creek in Boise County Wednesday morning.

The Boise County Sheriff’s Office says the crash happened on Idaho 21 around 8:18 a.m. The semi truck went into the creek at milepost 22, near Robie Creek.

The truck driver was not hurt in the crash, and was able to make it out of the cab to safety.

The sheriff's office says black ice is to blame for the crash.

"The driver stated, coming down the hill, every time he touched the brakes, he started to slide. When he came into this corner here he jackknfied and it pushed him into the creek," said Boise County Chief Deputy Steve Dorau.

Idaho 21 was blocked in both directions for more than six hours as emergency responders dealt with the wreck.
