Aims to clarify which folding seats are exempt from the SBR requirements. The wording “fitted in the access passages of vehicles of category M2 or M3” means to cover folding seats located in the entry/exit areas of buses and coaches as well as folded/stowed seats for occasional usage in the aisle areas of such vehicles. The wording “fitted to N1 or N2 for the safe ingress and egress of the driver via the front passenger door” means to cover folding seats that can typically be found in delivery vans, and where this front passenger door is frequently used by the driver to safely exit the vehicle (on the vehicle side away from traffic).
