What are you not allowed to carry on a bus?

You are not allowed to carry dangerous and malodorous materials on a bus because they can pose health risks or discomfort to other passengers. Additionally, carrying objects that can cause injuries is prohibited to ensure everyone's safety during the ride. Small animals in cages, however, are generally permitted because they are contained and do not pose a danger or nuisance. These rules help maintain a safe and pleasant environment for all bus passengers.
