Dual purpose vehicles are defined in the MOT Testing Guide. The unladen weight of a dual-purpose vehicle mustn't exceed 2,040kg. However, 4 × 4 pickup vehicles with a DGW over 3,000kg up to and including 3,500kg are considered dual purpose vehicles for test purposes if information about the unladen weight isn’t available.
