Who is permitted to carry a loaded firearm on a school bus?

The correct answer is peace officers because they are authorized personnel who have undergone specific training and are legally empowered to carry firearms while on duty. Their role includes ensuring safety and security in various settings, including schools and school transportation. Peace officers are trained to handle situations that may require the use of a firearm, making it appropriate for them to be armed in environments that involve children and students.

School bus drivers, passengers, and security guards typically do not have the same legal authority or training that peace officers possess, which is why they are generally not permitted to carry loaded firearms on a school bus. This restriction helps to maintain a safe environment for students and ensures that any firearm-related situations are managed by trained professionals.
