For a car owner, FASTag is simple: one tag, one class, recharge and drive. For a transporter or fleet operator it is a different exercise. Your toll fare depends on the exact vehicle class encoded in the tag, that class is decided by the type of vehicle and its axles, and getting it wrong means you either overpay at every plaza or get flagged for a class mismatch. Across many vehicles, those rupees and those errors add up fast.
This guide explains the commercial FASTag vehicle classes (the VC codes you will see on the tag and in your account), how axle count and weight decide which one applies, why the class must match your registration certificate (RC), and how fleet accounts let you manage many vehicles from one balance. It is based on the National Electronic Toll Collection (NETC) framework run by NPCI, with vehicle classification published by NHAI and IHMCL. Rules, rates and thresholds are revised periodically, so always confirm current details with NHAI/IHMCL or your issuing bank before acting on them.
How commercial FASTag classes actually work
Under the NETC programme a FASTag is encoded with a vehicle class (VC) code, and the toll plaza reader charges the toll mapped to that class. The reader does not weigh your truck or count its axles in real time. It simply reads the VC code stored in the tag and charges the toll for that class. This is why the code matters more than the colour or look of the sticker.
Tags do come in different colours by class as a handling aid: for example the car/jeep/van VC4 tag is violet, while heavier classes use orange, yellow, green, pink, blue and grey. But the colour is only a visual cue for plaza staff. The fare is driven entirely by the electronic VC code, so the class assigned at issuance must be correct for your vehicle.
- VC code = the vehicle class stored in your tag, used to calculate toll.
- The type of vehicle and its axle count decide which VC code applies.
- Tag colour = cosmetic indicator of class, not the value the system reads to charge you.
Commercial vehicle class (VC) codes by axle and weight
These are the vehicle classes as SBI lists them in its FASTag FAQ. SBI's list goes by the type of vehicle and the number of axles; confirm your exact class against your RC with your issuer.
- VC4 (violet) - Car / Jeep / Van, Tata Ace and similar mini light commercial vehicles.
- VC5 (orange) - Light Commercial Vehicle (LCV).
- VC7 (green) - Bus or truck.
- VC6 (yellow) - Three-axle commercial vehicle.
- VC12 (pink) - Vehicles with 4 to 6 axles.
- VC15 (blue) - Vehicles with 7 or more axles.
- VC16 (grey) - Heavy construction machinery and earth-moving equipment (HCM/EME).
Why the class must match your RC (and what mismatch costs)
A FASTag is issued against a specific registration number, and the class should reflect the vehicle as recorded in the VAHAN database and on your RC. If a truck is wrongly tagged in a lighter class, the system can flag a 'vehicle class mismatch'. You may then be asked to pay the difference at the plaza (often in cash), and a persistent mismatch can even lead the issuer to blacklist the tag, after which a fresh tag may not be issued against that number until it is corrected. If it is tagged heavier than it should be, you quietly overpay at every single toll for the life of the tag.
Separately, running a FASTag lane without a valid, active, sufficiently funded tag attracts a penalty: you are charged double the applicable toll for your class. For commercial vehicles that doubling is large in absolute terms, so the practical rule for fleets is simple: correct class, active tag, healthy balance, every vehicle, every day.
A class mismatch is fixable. You raise it with your issuing bank with the RC, and the class is corrected in the NETC mapper. If you would rather not chase the bank yourself, CareAll can help with class corrections, new tags and KYC. We are not SBI, NPCI or NHAI; we coordinate with your issuing bank for you.

Fleet and bulk FASTag: managing many vehicles
If you run more than a handful of vehicles, individual tags with separate recharges become a daily headache. Fleet (corporate/bulk) FASTag programmes are offered by major issuers such as SBI, HDFC, ICICI, Axis, Kotak and IDFC FIRST. Instead of topping up each tag, you typically load one central balance and it is shared across the tagged vehicles in the account. Exact account structure and features vary by issuer.
The real value of a fleet account is control and visibility, not just convenience. Typical features worth confirming with your issuer:
- A central wallet that funds the vehicles in the account, so no truck is stranded at a plaza for low balance.
- Per-vehicle and consolidated transaction reports (by truck, route or date range) for accounting and GST.
- Configurable low-balance alerts by SMS or email before a tag runs out of funds.
- Bulk onboarding of new vehicles and bulk recharge, instead of one-by-one.
- Auto-recharge / threshold top-up options to keep every tag active.
Setting up commercial or fleet FASTag: documents and steps
For a single commercial vehicle the process mirrors a car: choose an issuer, submit documents, complete KYC, and the tag is affixed and activated against your registration number. For a fleet, you open a corporate account with the issuer and add vehicles, often in bulk.
Keep these ready for each vehicle (single or fleet):
- Registration Certificate (RC) of the vehicle - this decides the correct VC code.
- KYC of the owner / business: PAN, address proof, and for companies the GST and authorisation documents.
- Owner / fleet-manager mobile number to be linked for alerts and the NETC mapper.
- A clear windscreen for tag fitment, and the vehicle's RC to confirm the class.
2026 updates fleets should know
The much-discussed FASTag Annual Pass (introduced at Rs 3,000, with the fee revised to Rs 3,075 from 1 April 2026 for FY 2026-27, valid for one year or up to 200 trips on eligible national highways and expressways) is for private, non-commercial Car/Jeep/Van only. It is validated against VAHAN and is deactivated if used on a commercial vehicle, so it is not a fleet cost-saving option. Commercial vehicles continue to pay per-class toll as usual. Confirm the current fee and eligibility on the NHAI/Rajmargyatra channels, as it is set annually.
GPS / satellite-based (GNSS) tolling is still under study (July 2026); the government is rolling out barrier-free MLFF plazas, which use FASTag, instead. For now, keeping every commercial tag correctly classed, active and funded remains the priority. For exact current toll rates, charges and any rule change, always confirm with NHAI/IHMCL or your issuing bank.
