Electronic Toll Collection: TAG Devices and Fines from July 1, 2026

Freight vehicles in Serbia no longer pay tolls in cash at the toll booth, but electronically, via TAG devices. The obligation began on January 1, 2026, but enforcement of the penalty provisions was postponed to give carriers a transition period. That period has ended: fines apply from July 1, 2026.

Who is obligated

The obligation applies to freight vehicles, that is, category IV vehicles under the toll classification. The legal basis is the Law on Fees for the Use of Public Goods ("Official Gazette of the RS", no. 95/2018, as subsequently amended).

If you're not sure which category a specific vehicle falls into, check before concluding that the obligation doesn't apply to you. The category depends on height and axle count, so mistakes happen easily in fleets with a mix of vehicle types.

Fines

The law prescribes different ranges depending on who is being fined:

For a company with multiple vehicles, the biggest risk isn't a single fine, but that the same violation repeats on every vehicle that isn't compliant.

The Belgrade bypass

For the Belgrade bypass, tolls are paid by registering a TAG device on the Toll4All platform. That is the only method of payment that complies with the regulation on that section of road, so vehicles that regularly pass through it should be checked first.

What to do if you're not yet compliant

1. Make a list of vehicles and determine the toll category for each one.
2. Check which vehicles already have a TAG device and which don't.
3. Check whether the devices are registered and whether the accounts have funds.
4. Pay special attention to vehicles that pass through the Belgrade bypass.
5. Decide who in the company monitors account balances, so a vehicle doesn't end up uncovered on the road.

An empty account is the same as not having a device

This is the most common mistake in practice. The device is installed, everything is formally in order, but the account runs out of funds mid-trip. From an enforcement standpoint, passing through without coverage is the same violation as passing through without a device.

That's why account balance is something to monitor the same way you monitor fuel, not something you check only when a notification arrives. If you already have a system that alerts you to events on your vehicles, it makes sense to apply the same approach here. We described how notifications are set up on the Alarms and notifications page.

Tolls as a line item in transport pricing

Electronic toll collection has one useful side effect: the toll cost becomes properly recorded by vehicle and by route. That means it can finally be compared against the planned route to see where the actual cost deviates from the assumption.

If you plan routes in advance, comparing planned versus actual cost per trip is the fastest way to see where money is being lost. We've written about planning on the Route planning and Transport optimization pages, and about reports on the Reports page.

For vehicles traveling to Hungary, the HU-GO system works on a different logic and is calculated based on distance traveled. We've written about this on the HU-GO Hungarian toll page.
