Can you point me to where an RV is considered "hazardous cargo"

Propane falls under the definition of a Class 2 hazardous cargo per the USDOT. The HC signs mean Hazardous Cargo. Members of this forum have been stopped and fined plus I have witnessed it myself.

Why not use the I-93 tunnel?
In the routing regulations, 49 CFR 397.67, in addition to following the
hazmat routes specified by the State, political subdivision or Indian
Tribe, the motor carrier must operate the vehicle over routes which do
not go through or near heavily populated areas, places where crowds
are assembled, tunnels, narrow streets or alleys, except when the
carrier determine that no other feasible alternative exists or that a
deviation is necessary because of an emergency. Thus, the
hazardous material carrier is generally prohibited under federal
regulations from using the tunnel. Under existing state regulations,
Massachusetts has already designated the I-93 and related CA/T
harbor tunnels in Boston as restricted routes prohibiting their use for
the transportation of hazardous cargoes.

Why can't I take my RV or camper through either the Baltimore Harbor or the Fort McHenry Tunnels?

Regulations govern the transportation of certain hazardous materials across our toll facilities. Under these regulations, vehicles carrying bottled propane gas in excess of 10 pounds per container (maximum of 10 containers), bulk gasoline, explosives, significant amounts of radioactive materials, and other hazardous materials are prohibited from using the Fort McHenry Tunnel (I-95) or the Baltimore Harbor Tunnel (I-895). The Francis Scott Key Bridge (I-695) is a convenient alternative route for crossing Baltimore's harbor.
