Tamil Nadu's Geology and Mining Department has extended the deadline for fitting GPS tracking devices on mineral-transport trucks to 31 October 2026, after nearly four out of five registered vehicles failed to comply with the requirement. The extension comes despite a Madras High Court order aimed at tightening oversight of construction mineral movement across the state.

Scale of Non-Compliance

Of the 1.4 lakh trucks registered on the Mineral Management System (MIMAS) portal, only 30,000 — roughly 21 per cent — had vehicle location-tracking devices installed as of 30 September. The remaining 79 per cent of trucks carrying M-sand, P-sand, and other construction aggregates remain without GPS units.

A Deadline That Has Already Slipped

The original compliance deadline of 31 March had been extended once before. The government had additionally announced that vehicles without GPS devices would be barred from receiving mineral transit passes from 1 September — a stipulation that appears not to have been strictly enforced. The latest extension followed formal representations from transport associations seeking additional time, according to department officials.

What GPS Linking Is Meant to Achieve

Integrating vehicle trackers with MIMAS is designed to record loading points and track truck movement in real time. Such data could help authorities identify supplies sourced from unauthorised quarries and build evidence trails in illegal extraction and transport cases — a persistent enforcement problem in Tamil Nadu's construction minerals sector.

Industry and Official Views Diverge

G. Ganesh, general secretary of the Tamil Nadu State Lorry Owners Federation, said the cost of compliant tracking devices had dropped sharply — from ₹15,000 to ₹3,700 — and that multiple vendors could supply over one lakh AIS-140-standard units. He argued that availability could no longer justify delays, adding that the government's reluctance to enforce the mandate raised questions about its resolve to curb illegal mining. Department officials, however, countered that the approximately 37 authorised suppliers did not hold sufficient stocks to equip all remaining vehicles within a short window.

Enforcement Context and What Comes Next

Officials confirmed that action is being taken against individuals generating fraudulent mineral transit passes using fake QR codes. A dedicated complaints number for quarrying violations is also reportedly set to be introduced and linked to the department's Chennai control room. The enforcement challenge is underscored by a stark demand-supply gap: Tamil Nadu's average daily requirement for construction aggregates is officially estimated at around 5.25 lakh units, against permitted quarry output of just 1.2 lakh units — a shortfall that critics say creates structural incentives for illegal extraction. The 31 October deadline will be closely watched as a test of whether the state can move from repeated extensions to actual enforcement.
