It happened around 3:00 Tuesday morning. Deputies and emergency responders were sent to 350 South and 100 East, near Vuteq and the Toyota plants.
Officials say Toyota had to be notified because it was blocking employees either heading to or leaving those plants. Around 6:30 the scene was cleared up and the semi was towed away.
No word on injuries, and it's unclear if weather played a factor in that accident.
