The Kufstein–Innsbruck section, together with the Brenner Autobahn and the German A93 and A8, form the main transport axis from Munich over the Alps to Verona and Modena.

In addition the A12 links Tyrol via the so-called German Corner (Deutsches Eck) to Salzburg and the West Autobahn (A1) to Vienna.

[1] During the summer vacation period in 2019, every weekend from mid-June to mid-September, on the section around Innsbruck as well as on A13 (Austria) Brenner Autobahn it was not allowed to leave the motorway to avoid a traffic jam.

The most important reason is to protect the local population suffering from the consequences of the denser traffic on rural roads leading parallel to the motorway.

Furthermore, whoever wants to avoid the traffic jam will find a pretext for his intention to leave the motorway in case of an inquiry by the Austrian police.
