Final answer:
Pupil Transportation Vehicles must indeed be equipped with an open door warning alarm and back up alarm, and this is a true statement as these features are crucial for safety.
Step-by-step explanation:
The statement that Pupil Transportation Vehicles must be equipped with an open door warning alarm and back up alarm is true. These safety features are mandated to ensure that both the driver of the vehicle and the surrounding individuals, including the pupils, are aware of the vehicle's movements. The open door warning alarm alerts the driver and nearby people when the doors are open, which is critical when pupils are boarding or alighting the vehicle. The back up alarm is especially important for warning those behind the vehicle when it is reversing.
