The Finnish Transport Infrastructure Agency is responsible for the road signs used on the highways. The Finnish road signs are specified in the Road Traffic Decree. All the road signs are presented on the attached pages.
Road signs starting from 1 June 2020
With the new Road Traffic Act, the yellow do not cross line will change to white and several new road signs will appear along roads from 1 June 2020. New road signs include merging lanes and minimum speed. In addition, many signs have undergone technical changes and they have been made clearer.
The transition period for the new road signs is 10 years. This means that both old and new road signs will be seen for years. Yellow do not cross lines will be changed into white with a slightly shorter transition period. The do not cross lines must be white by 31 May 2023 at the latest.
