WAKULLA, Fla. — Five people were killed and 25 injured when a bus carrying farmworkers collided with a tractor trailer causing both vehicles to burst into flames on a highway in the Florida Panhandle, CBS News reports.

The bus from Georgia was carrying roughly 34 adults and children when it ran a flashing red light before hitting the tractor trailer, then spun around and hit the semi again. The driver of the truck died as a result of his injuries. For the full story, click here.

NTSB investigators have been working closely with the Florida Highway Patrol (FHP), who responded to the accident site, according to a press release. The FHP documented the scene and preserved evidence relevant to the safety investigation, including both of the vehicles.

This is the third NTSB investigation of crashes involving agricultural workers since November 2015 when a motorcoach overturned in Little Rock, Ark., killing six. Six agricultural workers lost their lives June 18, 2016, when a 15-passenger van occupied by 16 people overturned in Ruther Glen, Va. The NTSB has been working with the Federal Motor Carrier Safety Administration and the Department of Labor on all three of these crashes.

The NTSB team, which will arrive in Florida on Thursday and is expected to be on-scene for up to a week, will be led by investigator-in-charge Jennifer Morrison. The team includes specialists in motor carrier, highway factors, vehicle factors, human performance and survival factors.

A preliminary report is expected within 30 days. Additional updates will be issued as circumstances warrant.
