Comparison of European road signs

Nearly all European countries operate a broadly similar system of road signs, road markings and traffic signals, but there are noticeable differences mainly in: Graphic design details Local regulatory significance The colour-coding of directional signs Local language texts (sometimes bilingual) The meaning and colour-coding of horizontal road surface markings Most European countries are party to the 1968 Vienna Convention on Road Signs and Signals and the associated European agreements supplementing it. A comparison of signage, however, reveals some significant differences at a national level—alongside less minor differences at a regional level.
