I'm in Switzerland for the summer doing some cycling. I'm wondering: Can I ride all the roads in Switzerland except for the autobahn?
For instance, between Bern and Fribourg, there's a major road labeled (on Google Maps) 12 and E27. That's the highway and I don't ride there.
But there's also a road labeled 12 that runs from Bern to Fribourg, a bit more directly, but it's just a two-land road, not a highway (perhaps it's the old highway 12?). Is it legal for me to ride on that road? (Google Maps won't let me drag my cycling route onto that road.)
In general, are there any roads besides the highway that I can't legally ride on?
