D405 branches off to the southwest from D8 near Jablanac towards Stinica ferry port - ferry access to Mià ¡njak, island of Rab (D105). The road is 4.8 km long.
This road, like all other state roads in Croatia, is managed and maintained by Hrvatske ceste, state owned company.
Traffic is not regularly counted on the road, however, Hrvatske ceste reports number of vehicles using Jablanac-Mià ¡njak ferry line, connecting D405 to the D105 state road. 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.
