Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements. California operates the second-largest school transportation system in the nation. Districts across the state—from LAUSD to San Diego, Fresno, and Sacramento—are actively hiring school bus drivers. With major routes along I-5, I-10, and US-101, and ongoing expansion of electric bus fleets, opportunities are growing.
Important: You must obtain both the School Bus (S) and Passenger Vehicles (P) endorsements on your CDL. Without both, you cannot legally drive a school bus in California. You’ll also need to pass a medical examination, background check, drug test, and complete ongoing safety training.
California’s electric bus transition: Many districts are adopting electric school buses for environmental sustainability and student comfort. Even with advanced technologies and automated systems, drivers still need a CDL with School Bus (S) endorsement—and most buses still use air brakes, requiring you to remove the “L” restriction.
Top California employers hiring school bus drivers:
- Los Angeles Unified School District (LAUSD)—2nd largest in U.S.
- San Diego Unified School District
- Fresno Unified School District
- Sacramento City Unified
- Private contractors: First Student, Durham School Services, Student Transportation of America
