GPS-Based Toll Collection in India — Complete Guide (GNSS Tolling)

Written and checked byRamanathan Virli· Roads & Infrastructure

India is replacing toll plazas with satellite-based GPS toll collection. Here's everything you need to know about the new GNSS system.

Union Road Transport Minister Nitin Gadkari has announced that India will shift to a GPS-based (GNSS) toll collection system, eliminating the need to stop at toll plazas. The system uses satellite tracking and On-Board Units (OBUs) to charge vehicles based on the actual distance driven on highways — not flat-rate booth charges.

Quick Facts

●Full form: Global Navigation Satellite System (GNSS)
●Announced by: Union Minister Nitin Gadkari
●Rollout for private vehicles: not notified (minister's stated target: end-2026)
●OBU device cost: not announced
●20 km free per day per direction
●Pilot: NH-275 (Bengaluru–Mysuru) & NH-709 (Panipat–Hisar)
●Live today instead: barrier-free MLFF plazas using FASTag (since 1 May 2026)
●Savings: ₹1,500 crore/year in fuel

What Is GPS-Based Toll Collection?

GPS-based toll collection (officially called GNSS-based Electronic Toll Collection) uses satellite technology to track a vehicle's movement on national highways and expressways. Instead of stopping at a toll booth, your vehicle's On-Board Unit (OBU) communicates with satellites to record the exact distance you travel. Toll is calculated automatically and deducted from your linked account — no barriers, no queues, no stopping.

How Does the GNSS Toll System Work?

The system has three main components working together:

›On-Board Unit (OBU): A small GPS device installed in your vehicle, similar to a FASTag tag but with satellite tracking capability.
›Satellite Tracking: GNSS satellites (GPS, GLONASS, NavIC) track the OBU's location as the vehicle enters and exits a tolled highway section.
›Central Processing System: The NHAI backend calculates the distance driven, applies the per-kilometre toll rate, and deducts the charge from your linked wallet/account.
›ANPR Cameras: For vehicles without OBU, high-speed Automatic Number Plate Recognition cameras capture the number plate and generate a toll invoice.

The 20 km Free Rule

One of the biggest benefits: under the revised National Highways Fee Rules (September 2024), vehicles using the GNSS system will get zero toll for the first 20 km of highway travel in each direction, once per day. This is a major relief for people living near highways who use them for short daily commutes. Beyond 20 km, toll is charged for the entire distance including the initial 20 km.

What Happens to FASTag?

No discontinuation of FASTag has been announced, and the barrier-free tolling rolled out so far depends on it:

›FASTag remains the toll payment system at National Highway fee plazas, which have accepted only FASTag or UPI since 10 April 2026.
›Multi-Lane Free Flow (MLFF) plazas — the first opened at Chorayasi on NH-48 in Gujarat on 1 May 2026 — remove the barrier but still charge your FASTag, using ANPR cameras alongside tag readers.
›OBU-based GNSS distance tolling has been piloted, but no date has been notified for private vehicles and no OBU mandate exists.

OBU Device — Price, Installation & Registration

The On-Board Unit is the key hardware for the new system. Here's what we know so far:

›Cost: not announced. MoRTH and NHAI have published neither a device price nor a distribution model, so any figure quoted elsewhere is speculation.
›Where to get one: not announced — no issuer, retailer or installer has been designated.
›Pre-fitment on new vehicles or retrofit on old ones: not announced.
›Payment linking: not announced.
›Treat any site selling a "GPS toll OBU" for private cars today with suspicion — there is no official device to buy.

Pilot Projects & Testing

The GNSS toll system has been piloted on two highway stretches in India:

›Bengaluru–Mysuru section of NH-275 (Karnataka) — one of India's busiest expressway corridors.
›Panipat–Hisar section of NH-709 (Haryana) — a key north Indian highway.

Rollout Timeline

What has actually reached the road so far is barrier-free tolling that uses your existing FASTag, not an OBU. No date has been notified for OBU-based GNSS tolling of private vehicles. The verified milestones:

›April 2025: the Ministry clarified there was no decision on a nationwide satellite tolling launch from 1 May 2025.
›17 December 2025: Nitin Gadkari told the Rajya Sabha satellite-based tolling would be in place nationwide by the end of 2026.
›10 April 2026: National Highway fee plazas stop accepting cash — FASTag or UPI only.
›1 May 2026: India's first Multi-Lane Free Flow (MLFF) barrier-less plaza goes live at Chorayasi, Surat–Bharuch section of NH-48, Gujarat — ANPR cameras plus FASTag, no barrier.
›11 May 2026: MLFF at Mundka–Bakkarwala plaza, Delhi. 19 June 2026: Daulatpura plaza on the Delhi–Jaipur section of NH-48, Rajasthan.
›1 August 2026: MLFF at Shahjahanpur on NH-48 makes the Manesar–Jaipur stretch barrier-free.
›September 2026: Gadkari describes the aim as barrier-free tolling across the highway network within a year.
›1 October 2026: Tamil Nadu's first MLFF plaza goes live at Paranur, Tambaram–Tindivanam section of NH-179B.

Benefits of GPS Toll vs Current System

The shift from booth-based to satellite-based tolling brings major advantages:

›Zero wait time: No queues, no barriers — vehicles don't stop at all.
›Pay for what you use: Distance-based charging is fairer than flat-rate booth charges.
›20 km free daily: Short-distance highway users near toll plazas benefit significantly.
›Fuel savings: Government estimates ₹1,500 crore annual fuel savings from eliminating idling at toll queues.
›Revenue increase: NHAI expects ₹6,000 crore additional revenue from reduced toll evasion.
›Pollution reduction: Less idling = lower vehicle emissions near toll areas.
›Accident reduction: Toll plaza areas are accident hotspots due to sudden braking — removing plazas improves safety.

What If You Don't Have an OBU?

During the transition, vehicles without an OBU will still be tolled using ANPR (Automatic Number Plate Recognition) cameras installed on highways. The camera captures your number plate, matches it with the VAHAN database, and generates a toll invoice linked to your vehicle. You'll receive the invoice digitally and must pay within the stipulated time, failing which penalties apply.

Frequently Asked Questions

What is GPS-based toll collection in India?

GPS-based toll collection (GNSS tolling) uses satellite technology and an On-Board Unit (OBU) in your vehicle to track highway distance and charge toll automatically — no stopping at toll plazas.

When will GPS toll collection start in India?

No date has been notified for OBU-based GNSS tolling of private vehicles. Nitin Gadkari told the Rajya Sabha on 17 December 2025 that satellite-based tolling would be nationwide by the end of 2026. What has launched is barrier-free Multi-Lane Free Flow (MLFF) tolling using your existing FASTag — first at Chorayasi on NH-48 in Gujarat on 1 May 2026. GNSS pilots were run on Bengaluru–Mysuru (NH-275) and Panipat–Hisar (NH-709).

Is the first 20 km of highway travel free with GPS toll?

Yes. Under the revised National Highways Fee Rules (Sept 2024), GNSS-equipped vehicles get zero toll for the first 20 km per direction, once per day.

Will FASTag stop working when GPS toll comes?

No. FASTag and GPS toll will run simultaneously during a transition period. Keep your FASTag active until the government officially mandates OBU.

How much does the GPS toll OBU device cost?

No price has been announced. MoRTH and NHAI have not published a price for the on-board unit or a distribution model, so any specific figure quoted online is speculation rather than an official rate.

What happens if I don't have an OBU?

ANPR (Automatic Number Plate Recognition) cameras will capture your number plate and generate a toll invoice. However, you won't get the 20 km free benefit.
