1. Tunnel category
A tunnel category is a classification used to determine which vehicles carrying dangerous goods may pass through a road tunnel. Under the ADR system, road tunnels can be classified from category A to category E according to the restrictions imposed on dangerous-goods transport.
Category A has no ADR tunnel restrictions, while categories B, C, D and E impose progressively broader restrictions according to the potential consequences of the dangerous goods being transported. Drivers carrying dangerous goods must compare the tunnel category with the tunnel restriction code applicable to their load.
What is an ADR tunnel category?
An ADR tunnel category determines which dangerous-goods transports are permitted or prohibited from passing through a particular road tunnel.
What do tunnel categories A to E mean?
Category A has no ADR tunnel restrictions. Categories B, C, D and E impose increasingly extensive restrictions on dangerous goods that could cause consequences such as explosions, toxic releases or major fires.
Do tunnel categories apply to ordinary passenger cars?
Normally, no. ADR tunnel categories specifically regulate vehicles carrying dangerous goods covered by the ADR rules. Other vehicles must still obey the normal traffic and tunnel regulations.
