The California Highway Patrol’s (CHP) Truckee Division says that a Greyhound bus driver caused a major interstate shutdown on Thursday.

According to a social media post from CHP, a Greyhound passenger bus was found abandoned by the driver during winter weather conditions on I-80 westbound, west of Donner Lake.

CHP called out the bus company after discovering that the driver allegedly left the bus on the interstate: “@greyhoundlines want to come pick up your bus that your driver abandoned?”

“Just in case anyone was wondering why 80 westbound was shut down in Truckee!!! Everyone say thank you,” CHP said in the post.

CHP followed up on the story by commenting, “We found the bus driver. The driver was done driving and got on another bus. Apparently they were done driving.”

Greyhound told local outlet CBS13 that the driver left the bus due to weather and a tire chain issue.

“Due to safety concerns, the passengers and driver were transferred to a passing schedule, returning to the original bus after speaking with highway patrol. Once repaired, the bus was then transferred to Reno,” the company said.

Winter weather continued to stymie traffic in the Truckee area into Friday.
