What is required regarding the passenger seat in a vehicle?

A passenger seat must be permanently attached to the vehicle to ensure the safety of occupants. This requirement is in place because a properly secured seat provides necessary structural support during a crash, helping to protect passengers from harm. A removable seat or one that can be replaced with another object, like a storage compartment, could compromise safety by not ensuring passengers are securely restrained and protected in the event of an accident. Additionally, regulations typically dictate that all seating positions in a vehicle be designed for occupancy to maintain passenger safety and adhere to safety standards. Proper attachment not only enhances passenger safety but also ensures compliance with vehicle safety regulations.
