We've had to do this at many of our commercial jobs in VA and MD. General Contractors usually require it of subs.

Joe Hinton Road. Itâs hard to believe that a road less than 1 mile long could make the list of most dangerous roads in Knoxville. However, over 33 crashes occurred on Joe Hinton Road in a span of just two years. Of these, 18 were single car accidents, and four were head-on collisions.
Death Road. La Carretera de los Yungas is, probably, the most famous road in the world as well as the most dangerous. This gravel dirt track covers a 69-kilometre (43 mi) stretch between La Paz and Coroico, in the Yungas region of Bolivia.
