How many folding seats are permitted in a bus?

Within the context of passenger buses, safety regulations and design standards dictate that buses typically do not have folding seats. The design of these vehicles prioritizes stability and safety, particularly in the event of sudden stops or accidents. Sturdy, fixed seats provide better passenger support and reduce the risk of injury. Folding seats can be less secure and may fail to meet safety standards, which is why they are generally not permitted in buses.

The restriction on folding seats is rooted in ensuring the safety of all passengers during transit. Thus, having a permissible quantity of folding seats is effectively zero, as safety considerations take precedence over flexibility in seating arrangements.
