NHAI Introduces Multi-Lane Free Flow Tolling

The National Highways Authority of India (NHAI), vide its Press Release dated May 2, 2026, has announced the launch of India’s first Multi-Lane Free Flow (MLFF) tolling system at the Chorayasi Toll Plaza on the Surat-Bharuch section of NH-48 in Gujarat. The system has been operationalised as part of NHAI’s efforts to introduce barrier-less toll collection and increase automation in tolling operations.

On the first day of implementation, approximately 41,500 vehicles traversed the MLFF-enabled corridor, highlighting the volume of traffic processed under the newly implemented system.

Under the MLFF framework, vehicles are no longer required to stop at toll plazas. Instead, toll collection is facilitated through an integrated technological interface combining:

1. Automatic Number Plate Recognition (ANPR) systems; and
2. FASTag-based electronic tolling mechanisms.

This model enables seamless and contactless toll collection while leveraging the existing FASTag infrastructure. The framework facilitates the collection of user fees without interrupting traffic movement.

At the core of the MLFF system lies the principle of barrier-less toll collection with minimal human intervention. Vehicles pass through designated tolling zones without stopping, and user fees are automatically determined and collected through the integrated system.

Recognising the possibility of payment failures, the framework introduces a post-usage enforcement mechanism:

1. In cases of insufficient FASTag balance, invalid FASTag, or non-functional FASTag, users are issued an Electronic Notice (E-Notice);
2. The user is required to pay the applicable user fee within 72 hours;
3. Failure to comply within the prescribed period results in the user fee being charged at twice the normal rate applicable to the vehicle category;
4. Continued non-payment may result in blacklisting of FASTag and restrictions on vehicle-related services through the VAHAN platform.

A notable feature of the MLFF framework is its emphasis on transparency in toll collection and user fee administration. The reliance on digital toll capture, automated notices and online payment mechanisms creates digital records of toll transactions and related notices.

Users are provided with:

1. Access to E-Notices through the designated digital portal;
2. A grievance redressal mechanism within the stipulated timeline; and
3. Visibility into outstanding toll obligations and applicable charges.

The introduction of MLFF represents a significant technological development in India’s toll collection framework. By replacing physical toll barriers with automated toll collection and enforcement mechanisms, the system is expected to improve traffic flow and support the development of a more efficient and cost-effective tolling ecosystem across the National Highway network.
