NHAI Rolls out Tamil Nadu’s First Barrierless Multi-Lane Free Flow Tolling System

---

1. At a Glance

• Multi-Lane Free Flow (MLFF) is a barrier-less tolling system. Overhead RFID readers read the FASTag, and ANPR (Automatic Number Plate Recognition) cameras read the Vehicle Registration Number (VRN). Toll is deducted while vehicles move at highway speed, so they do not stop at a plaza. [1][2]
• Tamil Nadu's first MLFF system is at Paranur Toll Plaza on the Tambaram–Tindivanam section of NH-179B. [1]
• It is the next stage of Electronic Toll Collection (ETC) after FASTag. The government links it to Ease of Living, Ease of Doing Business, less congestion, fuel savings and lower emissions. [1]
• UPSC relevance: GS-III (infrastructure, transport), e-governance, technology in public service delivery, and toll policy under the National Highways Fee Rules, 2008. [8]

2. Why in the News

• 01 Oct 2026: NHAI started MLFF tolling at Paranur Toll Plaza, NH-179B, the first in Tamil Nadu. [1]
• This is part of a phased national rollout. MLFF already runs at:
• Chorayasi (NH-48, Gujarat)
• Mundka-Bakkarwala (UER-II, Delhi-NCR)
• Shahjahanpur, Daulatpura and Manoharpura (NH-48, Rajasthan)
• Gharaunda (NH-44, Haryana) [1]

3. Background & Evolution

• Why MLFF: It removes stopping at plazas, which cuts congestion, travel time, fuel use, emissions and human involvement in toll collection. It also lowers the cost of building physical toll plazas. [1]
• Predecessor, FASTag: an RFID-based device fixed to the windscreen that pays tolls automatically from a linked account. [9]
• Milestones, in order:
• All lanes at NH fee plazas were declared "FASTag Lane of the fee plaza" for digital fee collection. [11]
• NHAI ordered double toll for vehicles whose FASTag is not fixed on the front windshield. [10]
• IHMCL (Indian Highways Management Company Ltd, a company promoted by NHAI) signed an agreement with ICICI Bank to build India's first MLFF system at Choryasi Fee Plaza, NH-48, Gujarat. A similar agreement was signed for Gharaunda, NH-44, Haryana. [4]
• NHAI started checking vehicle registration numbers against the tolling records to improve data accuracy. [12]
• 15 Nov 2025: amended NH Fee Rules took effect. Cash payers without a valid FASTag pay 2× the fee; UPI payers pay 1.25×. [8]
• 02 May 2026: Union Minister Nitin Gadkari launched India's first MLFF at Chorayasi Toll Plaza, Surat–Bharuch section, NH-48. [3]
• Next came Daulatpura (Rajasthan's first), Gharaunda and Manoharpura. [5][6][7]
• 01 Oct 2026: Paranur, Tamil Nadu's first. [1]

5. Multi-Dimensional Analysis

• Economic
• Lowers the cost of building physical plazas and running toll operations. [1]
• Saves fuel and time, which lowers logistics costs.

• Helps collect revenue for highway financing models that depend on tolls.

• Environmental

• Less idling and stop-start driving at plazas means lower vehicle emissions. [1]

• Scientific / Technological

• Combines RFID (FASTag) with ANPR (computer vision). [2]

• Depends on accurate VRN data, hence NHAI's VRN validation drive. [12]

• Ethical / Governance

• Less human handling makes collection more transparent and harder to leak or manipulate. [1]

• Open issues: privacy of camera-captured data, wrongful E-Notices (for example, cloned plates), and a fair process for appeals.

• Legal

• Enforcement depends on the penalty structure in the NH Fee Rules, 2008: the 72-hour window, then 2×. [2][8]

• India has no dedicated tolling-data protection framework yet. The DPDP Act, 2023 is relevant (not sourced here; check separately).

• Administrative

• Phased rollout across states. [1]
• Practical risks: users who do not keep a working FASTag with enough balance [1], foreign or interstate vehicles, and how E-Notices are recovered.

8. The Fine That Was Never Collected: A Warning from FASTag

• MLFF's main weapon against non-payers is a higher fee charged later. India has used this weapon before, and much of the money was never collected.
• From 16 February 2021, FASTag became compulsory. Vehicles without one had to pay double toll [13].
• CAG (Comptroller and Auditor General, India's top government auditor) found that NHAI did not recover this extra "double toll" money from concessionaires. A concessionaire is the private company that runs a toll road under contract and collects the toll [13].

• Result: a loss of ₹21.12 crore to the Consolidated Fund of India (the government's main account). Another ₹63.03 crore of double-toll dues was still waiting to be recovered [13].

• Why this matters more under MLFF

• At an old plaza, the double toll was taken in cash at the booth. Even then, it did not reach the government.
• Under MLFF, the 2× fee is due only after an E-Notice and a 72-hour window [2]. So the money has to be chased after the vehicle has already gone.
• A penalty is a real deterrent only if someone actually collects it. Otherwise the 2× rule exists only on paper.

9. The Barrier Moves from the Road into the Database

• MLFF does not remove the toll gate. It moves the gate into a vehicle database.
• At a plaza, the boom barrier stops a car that has not paid. Under MLFF, nothing stops the car. The only check is whether its number plate leads to a real, reachable owner.

• This is why NHAI first had to clean up its records by checking vehicle registration numbers against FASTag data [12]. If a FASTag is linked to the wrong number, the E-Notice goes to the wrong person, or to no one.

• This idea came from Parliament, but only as a stop-gap

• In February 2024, the Standing Committee on Transport, Tourism and Culture said ANPR cameras should be installed at the most congested plazas [15].
• It also said that a vehicle unable to pay should be let through, and sent a text message later asking it to pay [15].

• MLFF makes this "pass now, pay later" rule the normal way of working, not just a fix for congested plazas. That works only if the follow-up step reliably reaches the owner and collects the money.

• Faster tolling has already raised revenue

• The same Committee found that FASTag increased toll revenue. Shorter waits meant more trips, and going digital meant less money went missing on the way [15].
• MLFF can add to this gain only if recovery after the E-Notice works. If it does not, the money that went missing at the booth will now go missing during recovery instead.

10. A Faster Toll Is Not Always a Fair Toll

• MLFF makes collecting a toll faster. It does not check whether the toll should be charged at all.
• CAG's audit of NHAI toll plazas in southern India found ₹124.18 crore collected from May 2020 to March 2021 in breach of the fee rules. NHAI had not applied a 2013 amendment to the Fee Rules covering toll during delayed highway construction [14].
• At five plazas, CAG found an undue burden of ₹132.05 crore on road users [14].

• On one bridge built before 1956, no toll was allowed, yet ₹22.10 crore was collected [14].

• Why MLFF makes such errors harder to see and fight

• When a wrong charge is cut automatically from a moving car, there is no booth and no person to argue with.

• The user notices only later, as a bank deduction or an E-Notice. Without a fast way to complain, the user must prove the charge was wrong.

• The money problem also goes the other way

• The same audit found NHAI lost ₹133.36 crore because two NH-44 contracts in Tamil Nadu had no revenue-sharing clause [14].
• Better technology at the gate cannot fix a badly written contract. Tamil Nadu, now an MLFF state, has already seen this happen.

11. What NHAI and MoRTH Should Do Next

• NHAI should write recovery of E-Notice dues into every MLFF contract
• CAG found double-toll money stuck with concessionaires because no one enforced its recovery [13].

• MLFF agreements, like IHMCL's with ICICI Bank [4], should say clearly who collects the 2× amount, by when, and when it reaches the government.

• MoRTH should set up a time-bound appeal process for E-Notices

• The Committee's "pass now, text later" model [15] needs a matching way for users to dispute a notice.

• This could cover cloned plates, wrong VRN links or a tag that did not read. The user's money should not be held while the appeal is pending.

• NHAI should pre-register frequent users, as Parliament suggested

• The Standing Committee recommended express toll lanes for regular commuters who sign up in advance [15].

• Under MLFF, pre-registered vehicles with checked VRN data [12] are the least likely to receive wrong E-Notices.

• NHAI should check whether each toll is lawful before automating it

• CAG's findings of tolls charged in breach of the rules [14] show that every plaza should be checked against the NH Fee Rules, 2008 [8] before it switches to MLFF.

12. Anchors for Answers

• Data: ₹21.12 crore lost to the Consolidated Fund of India, and ₹63.03 crore pending, because NHAI did not recover double-toll dues from concessionaires after FASTag became mandatory [13]
• Data: ₹124.18 crore toll collected in breach of the Fee Rules (May 2020 to March 2021), plus an undue burden of ₹132.05 crore on users at five plazas [14]
• Report/Committee: Parliamentary Standing Committee on Transport, Tourism and Culture, 'Operation and Maintenance of National Highways and Management of Toll Plazas' (February 2024). It recommended ANPR at congested plazas, letting non-payers pass and asking them to pay later by text message, and express lanes for pre-registered users [15]
• Report/Committee: CAG Report No. 7 of 2023 (NHAI toll operations in southern India) [14]; CAG Report No. 12 of 2024 (double-toll recovery) [13]
• Law/Case: National Highways Fee Rules, 2008, including the 2013 amendment on toll during delayed construction and the 15 Nov 2025 amendment [8][14]
• Scheme: FASTag / NETC, the RFID base for MLFF. Parliament found FASTag raised toll revenue through shorter waits and less leakage [9][15]

13. Mains Relevance

• GS-III: Infrastructure (roads); investment models; science and technology in everyday life; environment (emissions).
• GS-II: E-governance and citizen-centric service delivery; transparency and accountability.
• Possible questions: 1. "Barrier-less tolling marks a shift from infrastructure-centric to data-centric highway governance." Examine the opportunities and risks of the Multi-Lane Free Flow (MLFF) system in India. 2. Discuss how technology-led toll reforms (FASTag to MLFF) improve logistics efficiency and transparency. What safeguards are needed for citizen data and grievance redress? 3. Toll revenue underpins India's highway financing models. Evaluate the role of electronic tolling in getting the most value from national highway assets.

15. Common Errors / Trap Areas

• India's first vs. Tamil Nadu's first: India's first MLFF is Chorayasi, Gujarat (NH-48), not Paranur. [1][3]
• Highway numbers: Paranur is on NH-179B, not NH-32 or NH-45. Gharaunda is on NH-44, not NH-48. [1]
• Who signed the agreement: IHMCL signed with ICICI Bank, not NHAI or MoRTH directly. [4]
• Penalty multipliers: 2× after 72 hours of an E-Notice (MLFF) is a different rule from 2× cash / 1.25× UPI for non-FASTag users at ordinary plazas. [2][8]
• Technology: MLFF uses RFID plus ANPR. It is not GNSS/satellite tolling. [2]
