A semi pulling a horse trailer jackknifed and rolled over in Nixa this afternoon, blocking traffic at Highway 14 and Tiffany.
Nixa Police say the driver was going too fast and swerved while trying to avoid hitting a car that was waiting to turn.
The driver of the semi was not seriously hurt.
Two horses were pulled from the trailer.
At least one was hurt, but both were able to walk away from the scene.
