Citing driver shortages, UC Berkeley’s Northside Safety Shuttle paused service again Sept. 18, less than one month after service was resumed.

Seamus Wilmot, director of campus’s Parking and Transportation department, said recent resignations and drivers on leave caused the Northside service to be put on hold. Wilmot also cited a nationwide bus driver shortage that has made it difficult to recruit new Bear Transit drivers.

Parking and Transportation notified students of the paused northside service through social media and the Night Safety Shuttle website, according to Wilmot. Wilmot added that users were also notified through the NextBus platform, which provides real-time routes each night.

The Southside Night Safety Shuttle is still running and experiences higher ridership than its Northside counterpart, according to Wilmot. Additionally, the Southside route serves most of the area served by the Northside route.

There is currently no estimate for when the Northside Safety Shuttle service will resume.
