Unfortunately those big honking PA Turnpike signs (https://www.google.com/maps/@40.0918477,-77.8108603,3a,15y,294.17h,93.4t/data=!3m6!1e1!3m4!1sfJ5iV_AO2-3EWCMfaj2cAg!2e0!7i13312!8i6656) use all generic names so I guess they can't count.

There's "Organic Peroxide" I think

that's a class of chemicals, just like all of the others on that array of signs.

It doesn't take a pharmacopeia to tell you which chemicals are bad. If it can kill you, it probably should be banned in certain spots.

O2 and N2 in excess of what they should be actually can be fatal.

Is that sign missing a "call to action"  at the bottom? "PROHIBITED VEHICLES _______?"  The other such signs I recall seeing have an instruction at the bottom such as "USE THIS EXIT" . (Like this one (https://goo.gl/maps/QdfKt8sW7Br).)

Mass Pike eastbound at I-95/128 (Interchange 14) has a sign reading "Propane LNG Cargoes Exit (with arrow)."
