Preliminary Inspection Responsibilities 1. Read and understand the job specification 2. Attend the pre-job conference 3. Become aware of safety hazards and responsibilities 4. Prepare inspection forms and inspection plan 5. Inspection of jobsite conditions 6. Inspection of materials 7. Inspection of equipment 8. Monitor ambient conditions
transporting students. The pre-trip inspection consists of two parts: a stationary inspection and an operating inspection. The stationary inspection consists of an interior and exterior inspection. The exterior inspection is also known as the “daily walk-around.” The operating inspection is performed while the bus is being driven.
