An unidentified male driver was airlifted out of South Lake Tahoe by helicopter Monday after crashing into a stoplight at the corner of Pioneer Trail and Highway 50, authorities said.

The crash occurred around 1 p.m. and resulted in eastbound Highway 50 traffic being rerouted to Pioneer Trail for at least an hour. The condition of the driver is unknown.

No one else was in the car during the incident, and no other vehicles were involved, said Travis Cabral, of the South Lake Tahoe Police Department.

Cabral said the driver was traveling eastbound on Pioneer Trail at the time of the incident when the vehicle crossed into the opposite lane and onto the sidewalk, taking out the stoplight as it continued westbound onto Highway 50.

The vehicle came to a stop with a pole to the traffic signal partially buried in it.

Tony Lento, a resident of Elizabeth Lodge on Pioneer Trail, said he heard the crash from inside his room.

“It sounded like, ‘Bam! Bam!’” Lento said. “I thought it was three cars or something in a wreck.”

Lento said the driver’s vehicle had also run over a mile marker in front of the lodge before striking the stoplight.
