Rest areas on German highways are generally of three types: the first kind is just a P sign, purely for drivers to take a break, without even a toilet, let alone gas stations or restaurants. The second kind has WC letters below the P sign, meaning that the previous type of rest area has added a toilet. The last kind is the kind of rest area we usually think of, with gas stations, restaurants, toilets, and even showers on the sign. Most of the toilets in such rest areas are paid, about 0.75 euros, but you can get a 0.5 euro coupon that can be used for shopping. Rest areas on Swiss highways are mostly the official, well-equipped ones with gas stations, restaurants, and toilets, and the toilets are also paid.
