European Electronic Toll Service (EETS)

EETS is the EU's electronic toll service, with Europe-wide compatibility; Switzerland is connected to the service. EETS helps to simplify and accelerate the cross-border movement of goods.

EETS is aimed at making it easier for users of the service to pay the tolls for using the European road network in EU member states by means of a contract with an EETS provider, an on-board unit and an invoice.
