A Perimeter Seating Bus (PSB) is the explicit legal designation used by British Columbia enforcement agencies to describe any commercial passenger vehicle engineered with lounge-style, wrap-around seating configurations designed to accommodate 12 or more passengers. This classification heavily impacts large stretch SUVs, modified Mercedes Sprinter vans, and full-scale party buses operating throughout the Lower Mainland and the Sea-to-Sky corridor. Because the seating arrangement differs from conventional forward-facing rows, the BC Ministry of Transportation subjects these vehicles to heightened mechanical scrutiny, structural safety inspections, and localized licensing protocols. Operators managing a registered PSB must hold a dedicated Special Authorization license and secure a valid National Safety Code number to transport groups. This designation separates recreational luxury party transport from standard multi-passenger commercial shuttle buses, enforcing strict internal safety rules to protect regional passengers.
