The payment and charging toll for driving on motorways is becoming more and more realistic practice in all the European countries. The introduction of tolls on Croatian highways extending into the early Seventies, when they were surrendered to transport the first two motorway sections. First it started with the physical collection of tolls at toll stations, and today, the guidelines tend to automated mode, charging tolls. Increasingly invoked the principle that users pay as much as possible the proportion of costs incurred by the transport of people and goods by highways. So, to pay for exactly as much travel. It is therefore necessary to find a modern, unified and fair system for electronic payment of tolls in the European Union, which will be user friendly, which requires a toll-free stopping. Croatia is in line with the European Union already initiated activities that are necessary to the electronic toll free in the transport stream actually established.
