"As to common laws - does anybody really think a 90' rig that would be fine out West belongs in the mountains of West Virginia? Individual state roads and geography dictate safe lengths of vehicles."


Have you ever been out west? There are real mountains out there, we just have hills in West Virginia. The Interstate Highway system was designed for the most part to a standard set of engineering guidelines. The combined length, weight, height, licensure requirements, on and on and on should be the same no matter where you are in the country.
