Two men are dead after a crash involving two tractor-trailers on Florida’s Turnpike in Orange County.

It happened around 5 a.m. Tuesday in the northbound lanes near mile marker 271, which is just south of the State Road 50 exit in Oakland.

Florida Highway Patrol troopers said a semi carrying recycled materials pulled off the road to check his tires.

When the driver, Larry Jones, 54, pulled back onto the Turnpike and was getting up to speed, the truck was rear-ended by a refrigerated tractor-trailer carrying flowers.

The driver of the refrigerated tractor-trailer, Donald Carroll, 35, was killed. Also killed was Jesse Singleton, 36, a passenger in that truck.

Troopers said Jones was going approximately 40-45 mph at the time of the crash.

Troopers said it was one of the worst semi crashes they have ever seen.

A second refrigerated truck was brought in to salvage many of the flowers, FHP said.

They have not determined why the second driver did not slow down or avoid the recycling truck.

The crash remains under investigation.
