Video from a CBS12 News viewer shows the scene. A 2020 silver Mercedes Benz C63 coupe can be seen wedged under a tractor-trailer. Palm Beach County Fire Rescue (PBCFR) said it was an underrun crash — when one vehicle goes underneath another.

According to Florida 511, the crash occurred at around 11:23 a.m. past exit 86 for S.R. 804, and the severity of the crash is listed as major.

Firefighters said the Mercedes received catastrophic damage. The driver of the Mercedes was pronounced dead at the scene by PBCFR paramedics, while the driver of the tractor-trailer was taken to Delray Medical Center for treatment.

Florida Highway Patrol (FHP) released preliminary findings following the deadly crash.

The driver of the Mercedes was allegedly speeding along the inside paved shoulder of the Turnpike. The report states that the driver of the Mercedeswas rapidly approaching the tractor-trailer, which was in the center lane, and failed to maintain control of the coupe.

FHP said the car traveled from the shoulder to the center lane and collided with the rear of the trailer. Due to the offsetting height of the vehicles, the Mercedes became entangled under the trailer.

Drivers are expected to see delays while first responders assess the scene. Traffic cameras show major congestion in the Boynton Beach area of the Turnpike.

At 2:34 p.m., PBCFR said all southbound lanes continue to be shut down to traffic.
