Yes — but only if you stick to secondary roads. The Swiss motorway vignette is required for driving on motorways and semi-motorways, which are marked by green road signs. If you avoid these roads and use only national or cantonal routes, you can drive without a vignette.
However, be aware that road checks are frequent, and if you are caught without a valid vignette on a motorway, you risk a fine of 200 CHF, plus the immediate purchase of the vignette (total cost of 240 CHF).
If you plan to avoid motorways, make sure to set your GPS or navigation app to “avoid toll roads and motorways”.
If you’re considering a longer stay or regular border crossings, it might be worth exploring the broader picture — including the pros and cons of living in Switzerland when it comes to transport, cost of living, and quality of life.
