 Where appropriate, the signs may be accompanied by the supplementary plate to diagram 620 (Except for access).

The sign to diagram 622.7 is used to give effect to an order prohibiting towed caravans. This might be used at difficult hills or narrow roads where an alternative route is available. It could also be used to protect unsuitable roads (e.g. narrow village streets or residential areas) close to a touring caravan site. If appropriate, the plate to diagram 620 (Except for access) may be used.

The sign to diagram 622.8 is used to give effect to an order that prohibits vehicles carrying explosives from using a length of road. This might be used at tunnels where the danger from such vehicles is likely to be greater or perhaps in urban or residential areas close to premises where explosives are manufactured. The need for the signs, other than at tunnels, is likely to be in areas known to have regular movement of explosives or inflammable materials. The sign must be accompanied by a plate to diagram 622.9 indicating either "No explosives" or "No inflammables or explosives". The plate to diagram 620 (Except for access) may be used where appropriate.

The sign to diagram 951 is used to give effect to a prohibition of cycling made under an order, or, more often, imposed by a byelaw. It is mainly used where there are pedestrian routes through housing estates which are not suitable for cycling because either their width or the visibility along them is not sufficient. In order to make such areas more accessible, local authorities are encouraged to provide suitable facilities for cyclists (see section 17 for the signing of cycle facilities). The sign to diagram 951 should not be used to indicate the end of a shared pedestrian and cycle facility (see para 17.36).
