An out-of-control SUV smashed a martial arts studio in Florida, injuring four students in a class, authorities said.

A woman suffered a “medical episode” about 7:30 p.m. Tuesday and drove straight into Master Roberts World Class Taekwondo in Oviedo, northeast of Orlando, police spokesperson Officer Lisa McDonald told WKMG.

Four teens attending class were slightly hurt when the SUV plowed through the window and landed on the dojang, police said.  

The students were not taken to a hospital but the driver was transported to the ER at Oviedo Medical Center, according to officials. Her condition was not immediately available.

The accident is under investigation.
