Roadworks

Roadworks can, however, also happen when a major accident occurs and road debris from the crash needs to be cleared.

There are standards of temporary traffic control established in each country for various type of road work.

In the United Kingdom, the government roadworks.org website aims to provide a national and live dataset of roadworks for the purpose of coordination and reporting.

The 1948[2] edition of the Manual of Uniform Traffic Control Devices specified the legend MEN WORKING to indicate roadworks.

The Federal Highway Administration (since 1990) and the Vienna Convention on Road Signs and Signals (since 1968) 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.
