1. "ADR directive" seems to concern a resolution practice in legal matters, too, as e.g. http://www.asauk.org...drdirective.pdf indicates. Which directive deals mainly with truck transport of dangerous liquids in public roads? Probably 98/91/EC is the most relevant? Does it concern only flammable liquids?
2. What is the essence of legal obligations for the truck owners, is there any real measure in case of truck collision or similar road accident? I have seen a fuel oil truck "ADR testified"; it look "armored", a lot of warning signs, etc. Liquid ammonia trucks seen leave the impression that ammonia could escape in the road in a case of collision.
3. Examples of main technical requirements: should all these trucks have double valves to avoid leaking out? Do liq NH3 or LPG trucks have PSVs and where does the exit of PSVs go? Do they have chassis to limit distortion at a collision?
Clarifications to the above would be highly appreciated, concerning either EU practices or even other recognized relevant practices not named ADR. Just to have a general idea, useful to Process mind. I know that requirements inside premises can be different than in public roads (post concerns public roads).
