Police are investigating a two-vehicle crash at a Carl's Jr. in the Kearny Mesa neighborhood on Saturday night, authorities said.
The incident happened in the 3800 block of Convoy St. at around 6:30 p.m., according to Officer Robert Heims of the San Diego Police Department.
A woman, 40, was driving in the drive-thru line with two passengers in a 2001 Honda Accord when she was rear-ended by a 1990 Toyota Tacoma.
The Toyota driver, a 23-year-old man, was traveling southbound and failed to follow the road's curvature. He "struck the south curb, launched and flipped end-over-end into the Carl's Jr. drive-thru wall," Heims said in a news release.
