The Oklahoma Highway Patrol says no one was hurt in a single-vehicle crash on I-244 near Sheridan Thursday morning.
Troopers said the SUV hit the inside wall and rolled onto its side, coming to rest in the two outside lanes of westbound I-244 at about 7:45 a.m.
The OHP says the driver wasn't injured. Troopers are investigating what caused the driver to hit the wall.
OHP also said rubbernecking from the wreck caused another accident involving three more vehicles.
Officers said a motorcycle came up on the accident, speeding, and tried to slow down, but ended up destroying his bike and hitting another vehicle.
A witness on scene said the motorcyclist looked shaken up but was awake and alert.
She said there were at least seven vehicles involved including the three-car rear-end collision.
