Traffic levels are regularly determined and reported by BINA Istra, operator of the motorway, and published by Hrvatske ceste. In 2010 the traffic volume was only measured in two sections: in the Učka Tunnel and between Lupoglav and Cerovlje. In 2011, traffic counting was started in each section of the A8 between Kanfanar interchange and the Učka Tunnel using the toll ticket counts. As of June 2012, only the ASDT figures for 2011 have been published. The largest AADT volume was recorded in the Učka Tunnel; it represents the only high-performance link between Istria and the rest of the Croatian motorway network.
