The definition of ‘light motor vehicle’ makes it clear that for a transport vehicle or omnibus, the gross vehicle weight of either of which or a motor car or tractor or road-roller the unladen weight of any of which, does not exceed 7500 kgs. ‘Gross vehicle weight’ has been defined in section 2(15). The motor car or tractor or road roller, the unladen weight of any of which does not exceed 7500 kgs. as defined in Section 2(48) of the Act, are also the light motor vehicle. No change has been made by Amendment Act of 54/94 in the provisions contained in Sections 2(21) and 10(2)(d) relating to the light motor vehicle. The definition of ‘light motor vehicle’ has to be given full effect to and it has to be read with Section 10(2)(d) which makes it abundantly clear that ‘light motor vehicle’ is also a ‘transport vehicle’, the gross vehicle weight or unladen weight of which does not exceed 7500 kgs. as specified in the provision. Thus, a driver is issued a licence as per the class of vehicle i.e. light motor vehicle, transport vehicle or omnibus or another vehicle of other categories as per gross vehicle weight or unladen weight as specified in Section 2(21) of the Act. The provision of Section 3 of the Act requires that a person in order to drive a ‘transport vehicle’ must have authorization. Once a licence is issued to drive light motor vehicle, it would also mean specific authorization to drive a transport vehicle or omnibus, the gross vehicle weight or motor car, road roller or tractor, the unladen weight of which, as the case may be, does not exceed 7500 kg. The insertion of ‘transport vehicle’ category in Section 10(2)(e) has no effect of obliterating the already defined category of transport vehicles of the class of light motor vehicle. A distinction is made in the Act of heavy goods vehicle, heavy passenger motor vehicle, medium goods vehicle and medium passenger motor vehicle on the basis of ‘gross vehicle weight’ or ‘unladen weight’ for heavy passenger motor vehicle, heavy goods vehicle, the weight, as the case may be, exceed 12000 kg. Medium goods vehicle shall mean any goods carriage other than a light motor vehicle or a heavy goods vehicle; whereas ‘medium passenger motor vehicle’ means any public service vehicle or private service vehicle or educational institution bus other than a motorcycle, invalid carriage, light motor vehicle or heavy passenger motor vehicle.
