The highway concessionaire has signed agreements with the Government of
La Rioja and the Regional Government of Aragón to enable certain routes free of charge, provided the
VIA-T device is used. For journeys between the Cenicero (10) links and Agoncillo (13), inclusive, and intermediate, tolls are free for users of VIA-T. Since February 1, 2008, light vehicles that perform return trips within a 24-hour period on any route between the Haro (9) links and Alfaro (16), inclusive, and intermediate, tolls are free for users of VIA-T. Until that date only the toll for the return trip was free, under the same conditions. Since February 1, 2009, if a return trip is made between the Gallur (19) and Zaragoza (23) links in a 24-hour period, light vehicles are free where the same route is taken for the outward and return journey and the same VIA-T device is used. In the Basque section a
social toll is applied, only to citizens registered in Álava, with discounts for those taking more than 25 trips per month. ==Traffic==
