Infrastructure Safety & Road Quality

German autobahns (A5, A6) are well-maintained but have unlimited speed sections; stay right except to pass. French autoroutes (A7, A9) are tolled, smooth, and well-lit. Expect speed cameras, especially in construction zones. Emergency telephones every 2 km. In case of breakdown, use orange emergency phones or call 112 (EU-wide).
