Why bother discussing 14 passenger buses? Well there is a very good reason to cover buses that are 14 passenger buses or less seating capacity. In order to drive commercial vehicles you are required to have a special licence call a CDL or commercial drivers licence. So if you do not have a CDL or are not interested in obtaining the licence then make sure you shoot for a 14 passenger bus or a bus with less passenger seating. So if your needs can be met without accomdating more than 14 passengers you may want to remember this when shopping for your new or used bus.
