FORT MYERS, Fla.- The Florida Highway Patrol is investigating a deadly accident that happened Friday morning on I-75, just south of the Colonial Blvd. exit. 

The rollover accident left a 51-year-old Fort Myers man dead. Thomas Johnson was not wearing a seatbelt at the time of the accident.

Johnson's Nissan Pathfinder hit the right rear of the trailer being pulled by a Ford F150 driving next to him. Johnson's vehicle rotated and drove off the roadway, overturning into a ditch and striking trees.

Traffic was slowed for hours, due to onlooker delays.
