Who is prohibited from accessing the rear door for boarding?

The correct answer to who is prohibited from accessing the rear door for boarding is that no one, including employees, may utilize this access point. This regulation is often in place for safety and operational reasons, ensuring that boarding occurs in a controlled environment, typically through designated front or central doors. This helps in maintaining order during the boarding process and reduces the risk of accidents or injuries.

By preventing access to the rear door for all individuals, including employees, it supports a consistent and safe boarding procedure, allowing for better passenger flow and security. Such policies might also ensure that emergency exits remain clear and accessible at all times. This approach aligns with general safety protocols often implemented in public transportation systems to enhance overall operational efficiency and ensure passenger safety.
