Each rest stop (area di servizio) along the Autostrada (freeway) has all services (gasoline, restaurants, cafeterias, coffee, shopping, restrooms, picnic area, some even hotels). Just look for AREA DI SERVIZIO signs. There is one every 10-30 kilometers, at times even more frequently. No difference from American Interstate highways, except for the tolls. Just stay in the right lane as the left lane is for passing only, and you cannot pass cars from the right. That specific route is famous for the hundreds of tunnels and viaducts, truly an engineering marvel. But although you may be tempted to look at the views from the high viaducts, concentrate on the road. Traffic travels fast and there are a lot of trucks, so be careful.
