The European Electronic Toll Service is designed to enable the payment of tolls through a single contract, a single EETS provider and a single vehicle device (OBU - On Board Unit) throughout the European Union.
Toll customers can enter into a contract with an EETS provider of their choice. The EETS providers pay the toll to the toll chargers, who in turn invoice their customers.
The basics of a European Electronic Toll Service are laid down in a directive. According to the directive, the European toll operators must implement the European toll service for vehicles over 3.5 tons maximum permissible weight (mpw) within three years and for all other vehicles within five years, if the toll service is an electronic toll system.
