The secretary may, by rule, designate an access route of more than 15 miles from a highway designated under this subsection when the longer route provides safer and better access to a location which is within the 15-mile limit. Household goods carriers may operate between highways designated under this subsection and points of loading and unloading.348.07(4m)
