MARTIN COUNTY — All southbound lanes of Florida’s Turnpike were blocked Friday morning and early afternoon following a fatal crash involving three tractor-trailers near the Palm City exit, according to the Florida Highway Patrol and Martin County Fire Rescue.

FHP was dispatched at 6:01 a.m. to the crash, which happened north of the exit at State Road 714. According to Martin County Fire Rescue, each tractor-trailer rear-ended the one in front.

A 67-year-old man of Orlando died at the scene, FHP investigators said.

This is what happened, according to FHP:

The 67-year-old was driving a tractor-trailer on the southbound lanes of Florida’s Turnpike.

Two tractor-trailers ahead of the man were stopped because of traffic. The 67-year-old failed to stop and crashed into one of the tractor-trailers, driven by a 64-year-old man of Haines City.

The 64-year-old man’s vehicle collided with a tractor-trailer driven by a 29-year-old man of Texas. He declined medical attention, according to Cory Pippin, Martin fire rescue spokesperson.

The 29-year-old was transported to Cleveland Clinic Martin South Hospital with minor injuries, Pippin said. Emergency responders pronounced the 67-year-old dead at the scene.
