There was a serious accident on South Church St. in front of the Pilot gas station on Wednesday night. Murfreesboro Police say that a female driver had a “possible medical episode” prior to or during the wreck.

Authorities report her vehicle left the roadway, jumped a curb and slammed into the side of a semi-truck, causing about 100 gallons of fuel to spill. However, Murfreesboro Fire and Rescue contained the spill.

Hazmat crews were called to the scene to clean the area.
