When I read the original request for comments I took "logging roads" as a term some people use for forest service roads in the US.  Originally created to facilitate logging access, these roads (380,00 miles of them) are used by both logging trucks and recreational vehicles.  USDA data reports that there are 1.7 million recreational vehicles on these roads daily, compared to 15,000 logging trucks.  There are local exceptions for use, including road closures for various reasons, so users do need to watch postings and beware of their setting.  That said, these are public roads and recreational users should never be discouraged from using them.

You may also be interested in the maps and a great app that is available describing all USFS roads, their conditions and advisories on use.  Be informed, be prepared, and enjoy yourself.  See fs.usda.gov
