If you have any queries regarding this or are wishing to transport dangerous goods which are not included above please see here for details of the category or alternatively contact Mersey Tunnels Police on 0300 3000 999 (recorded line) for clarification.

Any vehicle that is conveying a substance covered by the ADR Regulations must stop at the designated Police Declaration points prior to entering the Mersey Tunnels and the driver is to declare to Mersey Tunnels Police the nature and quantity of that substance.

For the avoidance of doubt failure to declare is a contravention of the Mersey Tunnels Byelaws and the driver may be reported and summonsed for contravening Section 7 of the Mersey Tunnels Byelaws (Dangerous Goods, Vehicles or Containers).
