The California Highway Patrol received a call at about 4:00 a.m. about a reckless driver heading east on Highway 198 near 99, west of Visalia.
Moments later, officers received another call saying the car went off the road and crashed.
Authorities say a man in his late 20s was driving a Honda Sedan at a high speed and veered off the roadway, crashing into a fence and rolling over.
The driver was not wearing a seatbelt and was ejected.
He later died at the hospital.
Alcohol is suspected to be a factor in this crash.
