Discuss how the Multi-Lane Free Flow (MLFF) tolling system represents a structural reform in India's highway monetisation model. What are its administrative and privacy challenges?

Launched at Chorayasi Toll Plaza on NH-48 (Surat–Bharuch) in Gujarat, the Multi-Lane Free Flow (MLFF) system is India's first barrier-less, non-stop electronic tolling framework, combining ANPR and FASTag [1][2]. It shifts highway monetisation from stop-and-pay collection to seamless, technology-driven revenue capture.

A structural reform

• Model shift: replaces physical barriers with post-facto digital recovery, moving from checkpoint-based to trust-and-enforce tolling [2].
• Cost efficiency: operational cost falls from ~15% to 3–4% of revenue, saving an estimated ₹5,000–6,000 crore/year system-wide [3].
• Logistics gains: no idling cuts fuel burn and emissions, supporting PM Gati Shakti; ~41,500 vehicles crossed on Day 1 [1][2].
• Institutional backing: CMV (Second Amendment) Rules, 2026 define "unpaid user fee" and enable scaling to ~25 plazas [2][4].

Administrative challenges

• Enforcement gaps: recovery depends on accurate plate-to-owner mapping via VAHAN; poor-quality plates and mismatched data cause revenue leakage [4].
• Coercive linkages: dues now block NOC transfer and Certificate of Fitness renewal, risking harassment of genuine disputants [4].
• Scaling complexity: uniform ANPR accuracy across weather and traffic remains untested at 25-plaza scale [2].

Privacy challenges

• Mass surveillance: continuous number-plate capture creates location-tracking datasets without a dedicated data-protection notification [1][4].
• Data governance: safeguards under the DPDP Act, 2023 for storage, retention and sharing remain unspecified.

Complementing MLFF with robust data-protection rules, grievance redress and eventual GNSS integration will make it a genuinely transformative, citizen-friendly reform.
