Tirol has various schemes on the A12 motorway to reduce the pollution. The air quality-based speed limit (from 17. November 2014) is one of the schemes. It is detailed below.

From 1 November 2016 the sectoral driving ban has been tightened to Euro VI.

There is also a motorway LEZ (pre-Euro 2 lorries over 7.5 T), a night-driving ban on pre-Euro 6 lorries over 7.5T, a sectoral driving ban (lorries over 7.5 tonnes), a night time speed limit (all vehicles) and a ban on overtaking (lorries over 3.5 tonnes). These other schemes are detailed on the pages linked from the menu on the right.
