Post-Trip Inspection and Reporting

The walk-through

A post-trip inspection is a required child-safety check, not a formality. Park the bus, set the parking brake, secure the keys, and walk the entire passenger compartment front to back, checking every seat, under seats, and the rear rows. Look inside the emergency exits and the storage areas. Confirm no student remains aboard. Then check for lost items, damage, vandalism, and mechanical problems that developed during the run.

Documentation and reporting

Complete the post-trip report, note any defects, and turn in required paperwork such as the student count, incident reports, and fuel or mileage records. Report mechanical defects to maintenance in writing so the next driver knows the status. Report any student incident or injury to the administrator. If a student is found aboard after the run, follow the district's protocol immediately and notify the dispatcher and school.

Traps to expect

Questions often test whether a driver may skip the walk-through on a short or empty run (no - do it every trip), whether the bus may be left unlocked, and whether a defect can wait until the driver's next shift (report it now). Another trap is assuming the aide performs the check; the driver is responsible.

Rule of thumb

Every trip ends the same way: brake set, keys secured, walk front to back, count, report.

California-Specific Laws and School Bus Regulations

Passing and stopping rules

California law requires traffic in both directions to stop for a school bus displaying flashing red lights and a stop arm on an undivided highway. On a divided highway with a median, traffic on the opposite side need not stop. Drivers may not pass a school bus with red lights flashing. The bus driver may not activate red lights at a location where students do not need to cross or board, and must use amber lights as a warning before stopping.

Equipment and operation rules

California requires school buses to meet specific equipment standards, including the stop arm, crossing gate, warning lights, and emergency exits, and requires drivers to use them as designed. Buses must stop at railroad crossings as described elsewhere. Cell phone use while driving a school bus is prohibited except for emergency communication. The bus may not be left unattended with students aboard.

Traps to expect

Questions test the divided-highway exception, the difference between amber and red lights, and the prohibition on leaving students unattended. Another trap is assuming a driver may use a hand-held phone for dispatch; the exception is narrow.

Rule of thumb

Amber warns, red stops traffic, and the median decides whether oncoming traffic must stop.
