The driver of the tractor trailer got out of the rig to check on the passengers in the bus. That's when a second bus rammed the back of the tractor trailer. A passenger vehicle was also involved in the crash.
Numerous ambulances were summoned to the scene.
A total of 17 people were injured on the two buses. Two people from the passenger vehicle were also injured. Officials say no one was seriously injured.
