Florida Highway Patrol officials said the southbound lanes of the Florida Turnpike were closed in Osceola County Saturday evening due to a car fire.
Osceola County government official Nickie Whisler said the car caught fire and ammunition inside the vehicle began to discharge near state Road 91 just after 6 p.m.
Whisler said no special techniques or equipment were needed to put out the fire and stop the ammunition from going off.
Officials said the incident began as a vehicle rollover, and the fire started at some point after the crash.
