ALACHUA COUNTY (WFLA) — A man and woman from California were killed Wednesday when their Tesla slammed into the back of a tractor-trailer that was stopped at a rest area along I-75 in Alachua County, the Florida Highway Patrol said.

Troopers said the Tesla was headed south on I-75 just before 2 p.m. when it exited for the rest area. For an unknown reason, troopers said the sedan entered the parking lot and struck the rear of the tractor-trailer.
