Hvaler Tunnel
Norway · Fv. 108 · 3.8 km
What this restriction means
This tunnel has no ADR category. The country has not assigned one — dangerous-goods traffic is governed by a national restriction regime instead.
A national restriction regime applies here. Its scope, hours and conditions follow the national decision, not the A–E scale of ADR 1.9.5, so no category letter can be quoted for this tunnel. Please check the source below before planning a route.

The restrictions cover dangerous-goods traffic to the extent and at the times set out in the national document. What may pass, and when, follows from that document, not from an ADR category — see the source below.
