We've had to do this at many of our commercial jobs in VA and MD. General Contractors usually require it of subs. We always do it at electrical boxes and outlets, risers, some plumbing pipes, and mechanical ducts before the fire marshal passes inspection. This varies from job to job because some of them require more prerocking than others.
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.
The logic was simple: The more sides a sign has, the more dangerous the upcoming stretch of road is. Circles (which were considered to have infinite sides) designated the riskiest hazards, like railroad crossings. Octagons denoted the second most perilous hazards, like intersections.
