The CAG’s NHAI Tolls Report flagged ₹132 crore excess tolls, while the PAC’s 33rd Report pressed for refunds, tariff fairness, and reforms. ABC Live connects these oversight findings with ministry accountability, asking: do audits and reforms really deliver a Return on Investment (RoI) for citizens?

Editorial Note — ABC Live

India’s tolling regime is undergoing a decisive transition. From perpetual tolling (charges never end, even after cost recovery) to barrierless toll pilots, these shifts affect millions of motorists and billions in revenue. Oversight institutions — the CAG and the PAC — are meant to ensure fairness, transparency, and accountability.

This analysis of NHAI Tolls Reports connects the CAG Audit Report No. 7 of 2023 with the PAC’s 33rd Report (2025–26). Unlike mainstream media that quotes them in fragments, ABC Live evaluates the full accountability cycle — CAG → PAC → ATR → Ministries → Citizens — and asks whether taxpayers truly see a Return on Investment (RoI).

New Delhi (ABC Live): India’s highways are more than just roads — they are arteries of commerce, mobility, and national growth. Yet for ordinary citizens, highways are also synonymous with tolls: recurring charges that keep rising, often without visible improvements in services. With the government now embracing perpetual tolling (where fees continue even after construction costs are recovered) and barrierless toll collection pilots, the debate around transparency and fairness has become urgent.

Two recent NHAI Toll Reports define this debate. The CAG Audit Report No. 7 of 2023 exposed systemic irregularities in toll collections, weak concession agreements, and failures in service delivery. Building on this, the PAC’s 33rd Report (2025–26) reframed those technical findings into citizen-focused prescriptions: refunding wrongful FASTag deductions, suspending tolls on incomplete roads, and establishing a Highway Tariff Authority.

But audits and recommendations alone do not deliver results. Unless the executive ministries — MoRTH and NHAI — act decisively, these reports risk becoming rituals of accountability without real-world impact. This analysis by ABC Live does what most mainstream coverage ignores: it connects audit evidence, parliamentary scrutiny, ministerial responsibility, and citizen outcomes — and asks whether oversight truly provides a Return on Investment (RoI) for taxpayers.

1. CAG NHAI Tolls Report (2023): Diagnostics in Action

Mandate: CAG, independent under Articles 148–151, audits financial and compliance irregularities.
Scope: Toll collection and concessions under MoRTH and NHAI.
Findings:
- ₹132 crore excess tolls in Southern India; ₹22 crore at Paranur Plaza.
- Weak concession agreements allowed leakages.
- Amenities are missing despite revenue.
- Technology delays in GNSS/ANPR tolling.
Strength: Precision, independence, credibility.
Weakness: Limited to diagnosis; no enforcement powers.

2. PAC NHAI Tolls Report (2025–26): Prescriptions and Reforms

Mandate: PAC, empowered by Articles 105, 118 and Lok Sabha Rules 308–314, converts CAG’s findings into reforms.
Key Recommendations:
- Suspend tolls on incomplete stretches.
- Automatic FASTag refunds for wrongful deductions.
- Highway Tariff Authority to regulate rates.
- Barrierless tolling pilots, but with privacy safeguards.
- Restructure NHAI and commission a new CAG audit.
- Drone/CCTV-based integrity framework.
Strength: Accessible, citizen-centric.
Weakness: Advisory only; dependent on executive compliance.

3. PAC’s Evaluation of the CAG NHAI Tolls Report

PAC examines the CAG’s findings line by line, questions ministries, and reframes them as issues of fairness.

CAG = Technical evidence.
PAC = Political accountability.
Limitation: PAC cannot enforce; it relies on ministries’ ATRs.

4. Comparative Snapshot: CAG vs PAC NHAI Tolls Reports

Aspect	CAG Report (2023)	PAC Report (2025–26)
Nature	Technical audit	Parliamentary oversight
Focus	Compliance irregularities	Citizen fairness & reforms
Language	Dense, data-heavy	Accessible, public-facing
Authority	Constitutional autonomy	Political legitimacy
Impact	Exposes misuse	Pushes reforms, demands ATRs

5. Cost & Efficiency of NHAI Tolls Oversight

CAG Reports:
- Cost ~₹1–2 crore per audit.
- Heavy, evidence-based diagnostics.
PAC Reports:
- Cost ~₹25–50 lakh per report.
- Lean, high-impact, reform-driven.
  👉 CAG = high cost, high diagnostic value. PAC = low cost, high policy impact.

6. Case Studies: Oversight RoI Across Sectors

Highway Tolls (2023): ₹132 crore flagged; RoI = 65–130x.
Telecom Spectrum (2010): ₹1.76 lakh crore loss flagged; RoI = 5,800–8,800x.
Coal Allocation (2012): ₹1.86 lakh crore loss flagged; RoI = 10,000x+

7. Citizens’ Return on Investment (RoI)

CAG = Indirect savings.
PAC = Direct relief (refunds, fair tariffs).
Combined cycle = Maximum RoI — but only when ministries act on ATRs.

8. Who Bears Responsibility for Delivering RoI?

CAG: Diagnoses misuse.
PAC: Prescribes reforms.
Executive Ministries (MoRTH/NHAI): Control contracts, policies, and refunds.
Parliament: Monitors ATRs but cannot enforce.
👉 Ultimate responsibility lies with ministries.

9. Ten-Year Perspective of NHAI Tolls Reports

CAG Reports: ~1,500–2,200.
PAC Reports: ~1,000–1,500.
ATRs: Delayed or incomplete, limiting effectiveness.
👉 RTI templates prepared to get year-wise data.

10. ABC Live Verdict

Audits without action are wasted democracy.
CAG can expose, PAC can recommend — but if ministries fail to act, every rupee spent on NHAI Tolls Reports becomes a sunk cost for citizens.

11. Why Ministries Hold the Key

Role: Refund citizens, suspend tolls, enforce penalties, set tariffs, and table strong ATRs.
Failures: No refunds, weak enforcement, delayed technology, perpetual tolling, vague ATRs.
Structural Barriers: Conflict of interest, revenue dependence, no penalties for non-compliance, and low citizen awareness.
👉 Ministries are the final executors of citizen RoI.

12. Implementation Failures: Who is Responsible?

a. Refund Failures

Despite CAG identifying ₹132 crore in excess collections, no systemic refund mechanism has been launched.

b. Weak ATRs

Ministries often file vague Action Taken Reports, with non-committal phrases like “noted” instead of measurable outcomes.

c. Contract Enforcement Gaps

NHAI tolerates concessionaires who overcharge or fail to provide services.

d. Policy Inertia

Perpetual tolling continues despite the PAC calling it unfair.

e. Technology Delays

GNSS and ANPR systems have remained stalled, despite promises since 2017.

👉 Bottom Line: Only ministries (MoRTH/NHAI) can enforce refunds, rewrite contracts, and deliver reforms. Their failures explain why citizens rarely see benefits from oversight.

13. Why ABC Live is Publishing This Now

India is transitioning to perpetual tolling and barrierless MLFF pilots in 2025. Without accountability, citizens risk indefinite payments for incomplete or poor services. ABC Live’s analysis of NHAI Tolls Reports is unique because it:
