Which route should I take to use my Liber-t toll tag?
By locating the symbols 
above the tracks. Depending on tolls, there may be:
- Reserved toll lanes with the electronic toll with a passage without stop, to 30 km/h,
- Reserved toll lanes electronic toll only for light vehicles,
- Reserved toll lanes "all classes" of vehicles,
- Mixed lanes which accept all payment methods including electronic tolls.
