Why Don't Medium Duty and Heavy Duty Trucks require Airbags?
According to GSO 42 regulation, Passenger Cars, MPV, Trucks or Buses with GVW less than 3500Kg requires an airbag, while for MDT & HDT Trucks, there is no such requirements.
Why So?
Don't Heavy vehicle require airbag since they have greater momentum while impact compared to Lighter vehicles?
