Going to Austria,suspect things have changed since 1990
Hi spaniard1,
Things have certainly changed in Austria since 1990, and the go-box has already been mentioned so I’ll stick to your next question. 
spaniard1:
Can anyone give me a few hints (ADR load)?
There is a new system of knowing which dangerous goods can be carried through road tunnels, and Austria’s system is particularly complicated, because escorts and extra amber beacons (over and above your standard ADR equipment) are sometimes needed.
Tunnels of more than 500meters in length on the main road network (in all ADR countries) should have been classified with a letter A-E by now, but not all countries have published the categorisation of their tunnels yet. Fortunately, Austria has completed this task, so it will be easy to advise you which tunnels your load can pass through and whether you’ll need an ■■■■■■.
When you say “ADR load,” do you mean: I have some bits and bobs of dangerous goods on board, or would it be a load that is fully subject to ADR please?
If your load doesn’t fall to be fully regulated by ADR, then you’re allowed through all tunnels.
If your load does fall to be fully regulated by ADR, then you’re generally allowed through tunnels of category “A.”
A category “A” tunnel either has a sign with an “A” on it, or no sign. If there’s no sign, it generally means there’s no restriction.
If you can say exactly what you’ll be carrying in the normal format please eg: UN number, PSN, UN Class, PG and ADR tunnel code it would be helpful.
The amounts and how it’s packaged would also be useful info too.
The ADR tunnel code for the goods is to be found in the last position on your transport document. Just for ease of explanation and to show you the info I need to be able to help you, I’ll use the example of petrol carried in drums…
Your transport document would look something like this:
UN 1203 PETROL, 3, PGII (D/E) [The unfamiliar bit at the end in brackets is the ADR tunnel code, which the consignor must provide.]
[I can provide it if it’s missing, but I need the exact UN number and name of the goods and packing group to be able to do that for you.]
The meaning of the D/E is:
The “D” = A petrol tanker may not pass through tunnels of categories D and E
The “E” = Other Carriage of petrol [packages (drums, IBCs etc)] may not pass through tunnels of category E.
If you have multiple UN numbers (eg a groupage type load,) then the most restrictive category letter must be applied to the whole load.
If there is a restriction, then the authorities must place a sign indicating the restriction and advising of an alternative route at a place where you have the opportunity to divert eg: this sign for the Mersey tunnels:
If you know your intended route, I can probably tell you the Austrian tunnel categories for the tunnels you’ll encounter.
I hope this helps.
