Barrier-Free Tolling Coming to Indian Highways

India's toll collection system is undergoing its most significant overhaul since FASTag was made mandatory in 2021. NHAI is accelerating the deployment of Multi-Lane Free-Flow technology — cameras, RFID, and GPS working together to collect tolls without ever stopping your car. Meanwhile, cash was banned at toll plazas on April 10, 2026, toll rates went up roughly 5 percent from April 1, and the FASTag Annual Pass has been repriced at Rs 3,075. And on the Bengaluru-Mysuru Expressway, India's first GNSS-based distance-tolling pilot is already running. This article breaks down every change and what it means for your highway journeys.

What Is Barrier-Free Tolling?

Barrier-free tolling — officially called Multi-Lane Free-Flow (MLFF) tolling — removes the physical boom barriers that currently stop every vehicle at a toll plaza. Instead of slowing down, stopping, and waiting for a barrier to lift, you drive through at highway speed. The toll is collected automatically in the background.

The technology relies on three layers working together. ANPR (Automatic Number Plate Recognition) cameras mounted over the highway read your vehicle registration number as you pass underneath at speed. RFID readers detect the FASTag tag on your windshield and link the read to your FASTag account. And GPS data from connected systems can record where a vehicle entered and exited a tolled stretch, enabling distance-based charging in the future.

The double-tolling problem — where a vehicle travelling long distances pays multiple flat tolls at successive plazas even for short use of each section — is also solved by MLFF. Once a vehicle's entry and exit points are tracked electronically, you pay only for the kilometres you actually used.

How the Technology Works

Picture driving under a gantry — a metal arch spanning all lanes above the road. On that gantry are high-resolution ANPR cameras pointed at each lane, RFID antennas broadcasting to FASTag chips in passing vehicles, and connected processing units that match the two reads in real time.

When an ANPR camera reads a plate that doesn't match any active FASTag read — indicating a vehicle without a valid FASTag — the system flags it. Enforcement cameras capture images for penalty notices. Penalty issuance is still being operationalised in India; currently, non-FASTag vehicles are charged 1.5x at manned lanes.

Current Changes: Cash Ban and FASTag Mandate

You do not need to wait for full MLFF rollout to feel the impact of these changes — several major shifts are already in effect right now.

For the vast majority of highway users, this changes nothing — FASTag penetration among highway users is already above 97 percent. But for older vehicles, vehicles where the FASTag has been blacklisted due to insufficient balance or mismatched KYC, or used cars that were recently purchased and not yet re-tagged, the cash ban creates a real risk of penalty charges on every toll plaza passage.

You can pay via UPI at toll plazas that have UPI-enabled terminals, but this is not universal across all plazas. The safest option remains ensuring your FASTag is active, linked to a bank account with sufficient balance, and associated with your registered vehicle number.

Toll Rate Hike and FASTag Annual Pass — New Prices

Alongside the technology overhaul, toll users are paying more from April 1, 2026. NHAI revised toll rates across national highways upward by approximately 5 percent — the annual revision tied to construction cost indices. On high-traffic corridors like Delhi-Jaipur, Delhi-Agra, and Mumbai-Pune, the effective toll for a return trip by car has gone up by Rs 10 to Rs 40 depending on the corridor.

For a detailed breakdown of which highway tolls increased by how much, see our dedicated article on the 5 percent toll hike from April 1, 2026.

To understand whether the annual pass makes financial sense for you, a rough calculation helps. If you drive the Delhi-Jaipur stretch (one way toll approximately Rs 280 post-hike for a car) six or more times a year return, the annual pass at Rs 3,075 pays for itself. The pass is not available for commercial vehicles — only private passenger cars and two-wheelers on eligible highways.

GNSS-Based Tolling: Distance Billing Is Here (On One Road)

The most forward-looking development in India's toll overhaul is the GNSS (Global Navigation Satellite System) based tolling pilot running on the Bengaluru-Mysuru Expressway. GNSS is the umbrella term for satellite positioning systems — GPS (American), GLONASS (Russian), Galileo (European), and NavIC (Indian) all fall under this category.

In GNSS tolling, a device fitted to the vehicle continuously communicates its position to a central system via satellite. When you enter a tolled highway section, the system logs your entry point. When you exit, it calculates the precise distance driven on that tolled section and charges you per kilometre — not a flat plaza fee.

The distance-based billing model solves several equity problems with current flat-toll plazas. A vehicle that uses only 5 km of a 100 km tolled expressway — say, entering at one point and taking the very next exit — currently pays the same full plaza toll as a vehicle using the full length. Under GNSS tolling, that short-trip user pays a fraction. This fairness argument is one of the key reasons the government is pushing the technology forward despite the infrastructure investment required.

Benefits for Drivers

The practical benefits of a mature barrier-free tolling system — once deployed at scale — are substantial for every highway user in India.

The benefits extend beyond individual drivers. NHAI estimates that removing bottlenecks at toll plazas will improve the average speed on national highways — directly reducing logistics costs for the trucking industry that moves goods across the country. Lower logistics costs eventually translate to lower prices for goods at the consumer end.

What About Privacy? GPS Tracking Concerns

Any system that tracks vehicle location in real time raises legitimate privacy questions. The GNSS tolling pilot has already drawn scrutiny from digital rights groups who note that continuous satellite tracking creates a detailed record of every vehicle's movements on the highway network.

NHAI's current position is that GNSS data collected for tolling purposes will be used solely for billing — not shared with law enforcement, not used for commercial profiling, and retained only for the billing period plus a dispute resolution window. However, these assurances are not yet codified in a dedicated legal framework.

For the ANPR camera component already in deployment, the concern is different — number plate reads are tied to vehicle identity, not continuous location. These records exist today at every FASTag-enabled plaza and are governed by existing IT Act provisions. MLFF simply increases the number of ANPR reads per journey without changing the legal framework around them.

Timeline: When Will Barrier-Free Tolling Roll Out Nationally?

NHAI has not announced a firm national deadline for MLFF deployment across all toll plazas. The rollout is being treated as a phased programme tied to greenfield highway construction and selected retrofitting of existing corridors.

The pace of rollout depends heavily on the budget available for gantry installation and the pace of new expressway construction. The Delhi-Dehradun Expressway, which opened in April 2026, and expressways in the pipeline for 2027–28 are expected to be built as MLFF-ready from day one rather than retrofitted later. Our expressway driving guide has the latest toll and route information for that corridor.

What This Means for Used Car Buyers and Sellers

For anyone buying or selling a used car in India in 2026, the evolving toll landscape has a few direct implications worth understanding before a transaction.

First, FASTag compliance is now non-negotiable. If you are buying a used car that was previously registered to another owner, confirm that the FASTag has been transferred or deactivated on the old owner's account and a fresh FASTag issued in your name. Driving on highways with an orphaned FASTag — one linked to the previous owner's account — can cause billing errors and disputes.

Second, as MLFF expands, vehicles with clear, unobstructed number plates become practically important. ANPR cameras must read the plate cleanly at speed. A faded, damaged, or non-standard aftermarket plate on a used car will be flagged by MLFF systems, potentially triggering penalties even with a valid FASTag, because the system needs both the RFID read and the plate read to match.

Third, for buyers considering commercial or longer-distance highway use, the FASTag Annual Pass at Rs 3,075 makes excellent financial sense. If you are evaluating a used car for a business that involves regular highway usage — sales reps, logistics, inter-city travel — factor the annual pass cost into your ownership cost calculation.

Finally, the price of highway travel is going up. With toll rates rising roughly 5 percent annually and new expressways being built with potentially higher per-km rates than older national highways, total cost of ownership for vehicles used on highways should include an updated highway toll estimate. Buyers who frequently travel on tolled roads should factor this into their budget alongside fuel, insurance, and maintenance costs.
