Road-adapted vehicle test excludes chain-mounted excavators from motor vehicle status and entry tax liability.

An excavator mounted on iron chain plates and used only for work-site operations was held not to be a motor vehicle under the Motor Vehicles Act definition adopted in the Tamil Nadu entry tax law, because it was not adapted for use upon roads. Physical verification showed no wheels or tyres, movement only on chains, and incapacity for road use without damaging the surface. The machine was treated as a special-purpose work-site apparatus rather than a road-suitable vehicle, and it therefore fell outside the entry tax net. A mechanically propelled machine is not a motor vehicle for entry tax purposes unless it is fit for use on public roads.

Issues: Whether an excavator mounted on iron chain plates and used for work-site operations, rather than on public roads, is a motor vehicle within the meaning of the Motor Vehicles Act, 1988 and consequently liable to entry tax under the Tamil Nadu Tax on Entry of Motor Vehicles Act, 1990.

Analysis: The definition of motor vehicle under the State entry tax law is derived from Section 2(28) of the Motor Vehicles Act, 1988, which requires a mechanically propelled vehicle to be adapted for use upon roads. The distinction drawn in precedent is between vehicles suitable for road use and vehicles such as caterpillars or military tanks that move on chain plates and are not made fit for public roads because they would damage the surface. On physical verification, the excavators were found to have no wheels or tyres, to move on chains, and to be incapable of road use without damaging the road. The excavators were therefore treated as special-purpose machines used at work sites and not as road-adapted motor vehicles.

Conclusion: The chained excavators were not motor vehicles within the statutory definition and were not liable to entry tax.

Ratio Decidendi: A mechanically propelled machine is not a motor vehicle for entry tax purposes unless it is adapted for use upon roads; a chain-mounted, work-site excavator that damages roads and is not road-suitable falls outside that definition.
