Safety Brake Set systems are designed to alert drivers if the parking brake is not set,
under a variety of conditions:
1) If the door is opened with the student load lights activated.
2) If the driver leaves the driver's seat.
3) If the wheelchair access door is opened or open. This system alerts the driver if
the brake is not set when the access door is opened and will also alert the driver if the
door is not closed when the parking brake is released.
4) Any combination of the above conditions as well as seatbelt/seat combinations.
