When should the "School Bus" identifier be marked on the front of a CR-3?

The "School Bus" identifier should be marked on the front of a CR-3 in multiple scenarios that ensure safety and compliance with traffic codes. Primarily, this identifier signifies that the vehicle is being used to transport students, which establishes a clear understanding among other road users of the bus's function and purpose.

Moreover, having the identifier present when involved in an accident is essential for informing law enforcement and other first responders about the nature of the vehicle involved. This can affect how they approach the situation in terms of assessing safety protocols or managing traffic.

Additionally, marking the bus at a bus stop is crucial as it alerts nearby drivers that children may be boarding or disembarking from the bus, helping to prevent accidents.

Therefore, the identifier should always be marked whenever the vehicle is performing its role as a school bus, which encompasses multiple scenarios such as ongoing transport, stops, and even accidents. This broad application ensures maximum safety and awareness for students and other drivers alike.
