Translations:Speed Limit Signs/6/en

To help anticipate if the next limit will involve a significant change of speed, speed signs are accompanied by appendix signs. If the next limit has a speed increase of 20 km/h or more, a green appendix with an arrow pointing up is added to the sign. In similar fashion, if the speed limit ahead has a speed decrease of 20 km/h or more, a red appendix with an arrow pointing down is added to the sign.
