A 38-year-old Yulee man died Tuesday night and his passenger was seriously injured in a crash on Blackmon Road in Nassau County, the Florida Highway Patrol said.
Troopers said Marvin Roberts was driving north "well above the posted speed limit" and missed a curve, driving through a ditch and hitting a concrete culvert before slamming into a pine tree.
Roberts died at the scene.
His 21-year-old passenger was taken to UF Health with serious injuries.
Troopers said neither man was wearing a seat belt.
