Actual use determines motor vehicle taxation, and a tractor-trailer carrying goods qualifies as a goods carriage.

For motor vehicle taxation, the decisive factor is the actual use of the vehicle on the relevant occasion. A tractor combined with a trailer for carriage of goods falls within the statutory concept of a goods carriage and transport vehicle, even if the tractor and trailer are separately registered. The Karnataka Motor Vehicles Taxation Act, 1957 operates as an independent code, so tax liability under it depends on the vehicle's use rather than on registration alone. Separate registration in another State does not prevent the taxing authority from examining the vehicle's actual character and use for levy purposes.

Issues: Whether a tractor-trailer used for transporting goods was liable to be treated as a goods carriage and transport vehicle for the purposes of permit requirements under the Motor Vehicles Act, 1988, and consequently assessable to tax under the Karnataka Motor Vehicles Taxation Act, 1957, notwithstanding separate registration of the tractor and trailer.

Analysis: The taxation statute was construed as an independent code, and the liability to tax under sections 3, 4, 6, 7 and 8 of the Karnataka Motor Vehicles Taxation Act, 1957 was held to depend upon the use of the vehicle on the relevant occasion. The Motor Vehicles Act, 1988 was examined for its definitions, especially of motor vehicle, tractor, trailer, goods carriage and transport vehicle. A trailer, though separately defined, remains within the broad definition of motor vehicle, and when a tractor and trailer are combined for carriage of goods, the combination answers the description of a goods carriage. The Court also held that the registration certificates issued in another State did not prevent the Karnataka taxation authority from examining the actual use and character of the vehicle for taxation purposes.

Conclusion: The tractor-trailer was rightly treated as a goods carriage and transport vehicle, permit under section 66 of the Motor Vehicles Act, 1988 was required, and the denial of exemption and levy of tax were upheld against the appellant.

Ratio Decidendi: For motor vehicle taxation, the decisive factor is the actual use of the vehicle on the relevant occasion, and a tractor-trailer used for carriage of goods falls within the statutory concept of goods carriage and transport vehicle notwithstanding separate registration of its constituent units.
