These standards are more demanding in both strength and system stiffness than those applicable to M2 category vehicles (vehicles with 10 or more seats). The requirements mean that the seatbelts are tested to perform under a mean deceleration of 20G - twice the amount demanded by the M2 test. The M1 requirements also include head impact requirements for possible secondary impacts in severe accidents.

The seatbelt systems include grabbers and the seats themselves are fitted with see-through head restraints. Ford also supplies a safety pack consisting of a first aid kit, fire extinguisher, various grab handles, rear step illumination and decals. Also available are ABS brakes and driver and passenger airbags.
