The Bulgarian Road Infrastructure Agency introduced new toll rates on 1 June 2026.

The amended tariff applies to vehicles over 3.5 tonnes and introduces a CO₂ component in line with Directive (EU) 2025/2459.

All vehicles first registered before 1 July 2019 are assigned to CO₂ Class 1. Zero-emission vehicles, including electric, hydrogen-powered, and hydrogen fuel cell vehicles, are assigned to CO₂ Class 5 without requiring any additional data.

Trucks first registered on or after 1 July 2019 and equipped with an internal combustion engine fall within CO₂ classes 1–4. To determine the applicable class, operators must provide the technical parameters from official vehicle documents. Classification in CO₂ classes 2–4 is valid for six years, after which the vehicle is reassessed against the current reference values.

The attached tariff table sets out the EUR/km rates by CO₂ class, vehicle type, emissions class and road category, including infrastructure, air, noise and CO₂ components.

An online CO₂ calculator lets operators determine a vehicle’s CO₂ emissions class by registering an account with a valid email address and entering the vehicle’s technical data in the national database. The calculator is available here.

Operators are advised to check the applicable CO₂ class and consult the attached tariff table before operating in Bulgaria.
