Vignettes costs for Switzerland and Austria
 

Recently there have been questions about these.
A one year Vignette for Switzerland costs 27 euros (for a bike)
A 10 day Vignette for Austria costs 4.40 euros (again for a bike)

These allow use on both ordinary roads and motorways.

This might just help you plan the most cost effective routes.

The vignettes are for use on the motorways, if you stick to the normal roads, then you don't need them. Warning tho, it is easy to drop onto a motorway without meaning too at some of the borders, and the police are well aware of this and lay in wait....

Ah nice one, just the information I was after. Is it possible to buy a vignette for Switzerland for less than a year? I'm planning on passing through in two or three days, and while I'd like to avoid the motorways, I'm not sure there are any other ways into Italy at this time of year, due to the mountain passes being snowed under. If any one knows of another way, I'd love to know!

Correct me, if I´m wrong, but I think the Swiss vignette is always for 1 year (and in fact it is from 1st December till the end of January the year after).

They claim it should be seen like a "road tax" - but personally I dont get it, why tourists should pay the same as locals, even if they are going to use the roads there for possibly no more than 1 day per year, and the locals use every day. Sounds like a rip-off to me. So I´ll take my time, and curve through the alpine passes (which is not a bad option at all!!).... right now this could be a bit challenging, though, as most of them will be closed until late spring or early summer.

But it´s a small country, and another way to not tolerate this is to go via France or via Austria (both of which will require payment for motorways, but not for the whole year).

I agree, my route will take me through Austria, is not expensive and the route passes near/through Munich Innesbruck- Italy.
The french motorways are not all charged. The basic rule is, if there is a suitable alternative then the motorway is charged, otherwise it is free, Use Viamichelin online to plan your routes to avoid or accept peages. Normally there will be a big sign Blue will warn and direct you to the peage, Green to the free alternative. Often written as (in green) Cityname Par RN and Blue city name par peage. (A for Auto route). For instance much of the A20,A75 and A18 is free. All (I think) in Brittany are free.

It is a common ploy to buy your vignette "2nd hand" from evil bay, stick it on to clingfilm, and sell it after your trip.
Bought mine for £14 and sold it a month later for half that.

It could cause problems doing that. To my mind it is better to use the free roads and motorways in Germany and spend £4 on an Austrian Vignette. That could work out cheaper and is completely legal. Normally you would be fine with a wrong vignette, UNLESS something else happens to cause the cops to take an interest in your bike.

For instance, coming from Calais to Italy, take the A16 towards Belgium, from Veurne use the road to Ypres thenpick up the free belgian motorways to Liege and on into Germany towards Munich. From there head south to cross Austria in the vicinity of Innsbruck. You can use motorways all the way, or the more leisurely side roads.

This really applies to the swiss vignette, but mine was looked at without any issues, stuck on the inside of my bikini fairing.
Obviously the Austrian one is short term, so not exchangeable.
