Swiss roads are generally good, although mountain routes can be narrow and winding. Chains and/or snow tyres may be required in winter, and after a heavy snowfall some routes may be closed altogether. There is a telephone number for information on national road conditions (tel: 163). Cars drive on the right. The maximum speed limits are 120kph (75mph) on motorways, 100kph (62mph) on dual carriageways, 80kph (50mph) on main roads, and 50kph (31mph) in towns.

On minor roads, traffic going up a mountain has priority, except postal buses when a yellow posthorn on a blue background sign is displayed (a line through this same sign cancels this). Road numbers on green signs indicate toll expressways, where a toll vignette (sticker) must be displayed. An annual road tax is levied on Swiss motorways - motorists should purchase a vignette at border points or from Switzerland Tourism before departure. Stickers are valid for one calendar year. The legal driving age is 18 and a national driving licence is sufficient documentation, although Green Card insurance is recommended. The maximum legal alcohol to blood ratio for driving is 0.05%.

There are two motoring associations in Switzerland. These are Touring Club Suisse (TCS) (tel: 0844 888 111; website: www.tcs.ch) and Automobil Club der Schweiz (ACS) (tel: (031) 328 3111; website: www.acs.ch).

Emergency breakdown service: TCS (tel: 140).
