ViaMichelin can provide you with toll costs for all journeys in Europe, including vignettes as used in Switzerland. This information is updated with each change in rates and takes into account winter and summer prices, in particular.
The toll cost is detailed for each toll barrier and is adapted for each vehicle used: car, motorcycle, camper van.
ViaMichelin will also indicate any crossings into restricted traffic zones, such as Critair in France. Tolls can be avoided by selecting the appropriate option in the route calculation stage.
