ADR tunnel codes

What the heck are tunnel code and tunnel category? In Europe, every tunnel has classified for ADR. Tunnel classification for ADR takes effect from 1st January 2010. And also every single UN number belongs to a tunnel code. The tunnel codes will need to be added to transport documents by consignors.

Hey, wait a second. So the tunnel has a tunnel category and every substance has its own tunnel code. How can I pair them? Let’s see.

There are 5 different tunnel categories.

Tunnel category “A” is the weakest. There is no sign. So you can pass with any dangerous goods. Category “E” is the strongest. The passage is restricted for vehicles carrying dangerous goods, except few UN numbers.

Remember, this sign belongs to the tunnel! How does it look like?

OK. And what about tunnel code? The tunnel code belongs to the material or goods (UN number). The consignor has to provide this information with the proper shipping name. The ADR says :”The tunnel restriction code need not be added in the transport document where the carriage is known beforehand not to pass through a tunnel with restrictions for carriage of dangerous goods.”  In most cases, consignors provide tunnel codes if necessary.

But how does it look like, and where can I find it?

Ok, So how can I figure out whether I can go through the tunnel or not? A piece of cake. Make sure the consignor provide the tunnel code on the docket. If you have the tunnel code you’ll be able to check the restricted tunnels with the following table.

Let’s see a sample. You are transporting packaged hazardous goods with tunnel code C/E and you are facing to a tunnel with category B. According to the table C/E means : “for tanks : passage forbidden through tunnels C, D, E. But you are not driving a tank. You have packages on the vehicle. Others carriage. Passage forbidden through tunnels of category E. Only E. So yes, you can go through on B tunnel. Don’t worry about B1000C and similars. These codes belong to explosive substances.

In Ireland, we have only one tunnel classified for ADR, the Dublin Port Tunnel. If you would like to read more details about Dublin Port Tunnel, click on the picture.

My suggestion: Transport companies carrying hazardous goods in Europe make a route plan and double check every serious tunnel on the way to the destination to not to get into trouble. Very risky tunnels like Mont-Blanc or Frejus has own regulations so better to visit their websites before you hit the road.
