Road signs in the United Kingdom and in its associated Crown dependencies and overseas territories conform broadly to European design norms, though a number of signs are unique: direction signs omit European route numbers, and road signs generally use the imperial system of units, unlike the rest of Europe.

Except for route numbers, there are a maximum of three signs on a pole, with the most important sign at the top. All signs have a reflective layer added on selected parts of the sign as is custom in European countries; most larger signs also have their own illumination.

They generally largely follow the general European conventions concerning the use of shape and color to indicate their function.

Road signs in Lithuania conform to the general pattern of those used in most other European countries as set out in the 1968 Vienna Convention on Road Signs and Signals. Due to the country being occupied and annexed by the Soviet Union between 1940 and 1990, when it restored its independence, modern road signs used in Lithuania are in many ways similar in design to road signs used in the Soviet Union before its dissolution in 1991. This design of road signs is still used in most post-Soviet states, in particular Russia, Belarus, and Ukraine. Neighboring post-Soviet Baltic countries Latvia and Estonia, which were also occupied by the Soviet Union in 1940, have significantly modified their road sign designs, resulting road signs in these two countries being extremely different in design from road signs used in most other post-Soviet states.
