D406 branches off to the southwest from D8 near Prizna towards Prizna ferry port - ferry access to Žigljen, island of Pag (D106). The road is 2.9 km long.[1]
As with all other state roads in Croatia, the D406 is also managed and maintained by Hrvatske ceste, state owned company.[2]
Traffic is not regularly counted on the road, however, Hrvatske ceste report number of vehicles using Prizna-Žigljen ferry line, connecting D406 to the D106 state road.[3] Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the road connects to a number of summer resorts.
