Motorways Motorways (, ) form the trunk of the road network, and similarly to other European countries they include at least 2 lanes in each direction, as well as an emergency lane on the right and auxiliary lanes for entering and leaving the motorway in intersections. In both countries, motorways use white-on-green directional signage. The general speed limit for motorways in both countries is 130 kilometers per hour, which is implicitly decreased to 80 km/h (Czech Republic) or 90 km/h (Slovakia) in urban areas. In both Czech Republic and Slovakia, motorways are designated by a number prefixed by the letter D. Both countries also use red rectangular shields with the motorway number in both countries, although in Slovakia the shield includes the D prefix, while in the Czech Republic it only contains the number itself. Slovakia, as well as the Czech Republic before 2016, also operates a complementary expressway network (, ), which consists of limited access highways that don't fully meet the motorway standards. They are designated by a number prefixed by the letter R. Slovak expressways use similar highway shields as motorways, albeit with the different prefix. The term "motor vehicle road" (, ) has also been used variably to refer to the network, although in both countries this term is now used for a separate category of roads. The same rules of the road as on motorways also apply on expressways, including the speed limits and the white-on-green signage, although they used to be legally distinct from proper motorways and instead considered to be a part of the regular highway network. This led the Czech Republic to discontinue the system in 2016, when most former expressways were upgraded to motorway status, while Slovakia passed an amendment in 2020 that redefined expressways as a type of motorway. In both countries, all motorways and expressways
