Tamil Nadu Halts Permits for Mineral Trucks Lacking GPS Trackers

On Sunday, November 1, a lorry carrying river sand, blue metal or M-sand on a Tamil Nadu highway without a GPS box wired into a state government portal stopped being allowed to load again. The Directorate of Geology and Mining shut off fresh transport permits and transit passes to any mineral vehicle that had not fitted an AIS 140 compliant tracker and linked it to the department's Mineral Management System, or MiMaS, after a deadline that had already been pushed back three times.

The numbers behind that cut off are stark. Tamil Nadu has about 1.4 lakh vehicles registered on the MiMaS portal to haul minerals. As of September 30, only around 30,000 of them, roughly a fifth, had the GPS unit fitted and verified. Close to 1.1 lakh trucks, about 79 per cent of the fleet, had not complied, according to figures reported by TN News.

That gap is why this is a story for more than a mining ministry file. A large share of the sand, aggregate and M-sand that feeds Tamil Nadu's building sites moves on these trucks. A rule meant to choke illegal quarrying can, if enforced to the letter, also choke the supply of construction material to ordinary building sites if tens of thousands of trucks are suddenly off the road. Fleet owners outside Tamil Nadu have reason to watch too. AIS 140 tracking is already compulsory for public service vehicles, national permit trucks and vehicles carrying hazardous goods across India, and states have shown they will extend it further into specific goods categories when enforcement pressure builds, as it has here around sand mining.

The department did not arrive at November 1 in one step. The original deadline for fitting the devices was March 31, 2026. When compliance stayed low, the government pushed the cut off to September 1, then to September 30, then to October 31, each time citing the scale of the task. Officials pointed to a supply bottleneck on the way: only about 37 authorised device suppliers were approved to fit and register the units, and they could not equip 1.1 lakh vehicles in a short window, one official said, as reported by TN News.

Truck owners see it differently. "The cost of tracking devices had fallen sharply, from Rs 15,000 to Rs 3,700," G. Ganesh, general secretary of the Tamil Nadu State Lorry Owners Federation, told TN News, questioning whether the government would actually hold the line on enforcement this time. Vehicles caught moving minerals without a fitted and integrated GPS device now face inspection, seizure and what the department has called stringent criminal action, Hans India and DT Next reported.

The question that stayed open through four missed deadlines has not gone away on the fifth. If the mining department seizes trucks at the scale its own numbers suggest it could, Tamil Nadu's construction sites will feel it before its quarries do. Whether the state holds this deadline, or finds a fifth extension, will decide which happens first.
