In Slovenia during holidays there is traditionaly increased traffic mostly on motorways from Austria to Croatia.
Therefore long queues are expected in entering points from Austria to Slovenia, i.e. Karavanke tunnel (A2) and Sentilj/Spielfeld crossing (A1). Important reason for these queues is that drivers don't have vignette for Slovenian roads and have to buy them at the border. To reduce or even avoid long waiting periods drivers are strongly recommended to buy vignette for Slovenian motorways online. They can do it here.
