Sub School Bus Drivers typically hold the same credentials as School Bus Drivers, including a valid CDL with passenger and school bus endorsements. They work on a temporary or substitute basis, filling in for regular drivers, and often have flexible schedules. School Bus Drivers usually operate regular routes, with fixed schedules and are employed full-time or part-time in permanent roles. Both roles require similar certifications but differ mainly in employment type and work consistency.
