Signage

Typically, roadworks signs are indicated by an orange diamond in most MUTCD-influenced countries. The 1948 edition of the ''

prohibit the use of the "MEN WORKING" legend, replacing with the legend "ROAD WORK" and the symbolic roadworks sign (typically using a gender-neutral silhouette) respectively. The worded legend of the warning sign upcoming roadworks, which is banned by the 1968 Vienna Convention on Road Signs and Signals because UN-compliant signs must make use of more pictograms, is allowed in the United States by the 2009 MUTCD.


Lane markings

In some countries, where lanes must be altered so as to accommodate roadworks, the new lanes (or interim lanes) are marked with a different colour and take precedence over the previous lanes. In Germany, Poland and many other European countries, it is yellow; in Switzerland and in Ireland, it is orange.
