In California they are called "freeways." What are they called in each of these countries? a. Great Britain? b. Germany?

While the purpose is the same—moving high volumes of traffic at high speeds—the names for major divided highways vary significantly by country, reflecting their language and history. In Great Britain, these essential routes are known as motorways. The name is quite literal, designating a "way" specifically for "motor" vehicles. Identified by an "M" prefix, like the famous M1 connecting London to Leeds or the M25 orbital road, these routes are the backbone of the nation's transport network (Review), serving the same function as interstates in the United States.

Across the channel in Germany, the equivalent is the world-renowned Autobahn. The name translates directly to "car path" (from "Auto" for car and "Bahn" for path or track). The German Autobahn system is one of the oldest and most famous highway networks, particularly known for its sections that have no federally mandated speed limit. While an advisory "recommended speed" (Richtgeschwindigkeit) of 130 kilometers per hour (about 80 mph) exists, drivers on these unrestricted stretches are legally permitted to travel as fast as they deem safe.

Interestingly, the Californian term "freeway" highlights a different aspect altogether. It originally referred to a road that was "free" of tolls and "free" of at-grade intersections like stoplights or cross-streets, ensuring a continuous, or free-flowing, journey. Each name—motorway, Autobahn, and freeway—simply emphasizes a different characteristic of the same type of modern road.
