For trucks over 3.5 t, Bulgaria has been charging a distance-based toll (TOLL, operated by BG Toll) since March 2020 on motorways and class I and II roads. Since 1 June 2026, the vehicle's CO₂ emission class is also included in the calculation (implementing EU Directive 2022/362) – better CO₂ class = lower rate.
Official rates (EUR/km incl. VAT, valid from 1 Jun 2026), examples on the motorway:
| Vehicle | Euro 0–II | Euro III–IV | Euro V | Euro VI | CO₂ class 4 (LEV) | CO₂ class 5 (EV) |
|---|---|---|---|---|---|---|
| Truck >12 t, 4+ axles (40 t) | 0.34 | 0.29 | 0.26 | 0.21 | 0.17 | 0.14 |
| Truck >12 t, 2–3 axles | 0.23 | 0.22 | 0.18 | 0.14 | 0.12 | 0.09 |
| Truck 3.5–12 t | 0.12 | 0.11 | 0.10 | 0.08 | 0.06 | 0.04 |
On class I roads the rates are about €0.01–0.03/km lower, with further discounts on class II roads. Vehicles up to 3.5 t (incl. cars) continue to use the e-vignette instead of the km toll. TollCalc tip: For trips from 1 Jun 2026 the official CO₂ rates are applied automatically – remember to store the truck's CO₂ class.
