According to 13 CCR 1217: “…the number of passengers shall not exceed the number of safe and adequate seating spaces…” MDUSD has set the following guidelines in order to assist schools/departments in maintaining safe seating on district school buses when planning trips:


Pre-kinder to 3rd grade: Three passengers per seat up to 90% of the maximum seating capacity (rounded down to the nearest whole number). Adult chaperones may limit the seating capacity and can be configured two to a seat.


4th grade to Adult: Two passengers per seat. Maximum passenger load 52 in big buses.


In no event will the driver allow more passengers and equipment to exceed the safe seating and the maximum weight rating of the vehicle he or she is in charge of. The driver has the authority and discretion to reduce or limit passengers and equipment in order to maintain a safe control of the vehicle.
