 Traffic is regularly counted by means of traffic census at toll stations and reported by Autocesta Rijeka–Zagreb and Hrvatske autoceste—the operators of the northern and the southern portions of the motorway respectively.The reported traffic volume gradually decreases as the motorway chainage increases and as it passes by various major destinations and the interchanges that serve them.Thus the greatest volume of traffic is registered between Jastrebarsko and Lučko interchanges – with 31,432 vehicle annual average daily traffic (AADT), and 53,216 vehicle average summer daily traffic (ASDT) figures as that is the section closest to Zagreb.
