Tunnel restriction codes
The restrictions for the transport of specific dangerous goods through tunnels are based on the tunnel
restriction code of these goods, indicated in Column (15) of Table A of Chapter 3.2. The tunnel
restriction codes are put between brackets at the bottom of the cell. When ‘(─)’ is indicated instead of
one of the tunnel restriction codes, the dangerous goods are not subject to any tunnel restriction; for
the dangerous goods assigned to UN Nos. 2919 and 3331, restrictions to the passage through tunnels
may, however, be part of the special arrangement approved by the competent authority(ies) on the
basis of 1.7.4.2.
When a transport unit contains dangerous goods to which different tunnel restriction codes have been
assigned, the most restrictive of these tunnel restriction codes shall be assigned to the whole load.
