Diagram 622.7 is used to stop caravans being towed through unsuitable roads that may have very narrow points. The no caravans sign may also be used to stop a heavy flow of traffic through small villages near a touring caravan site.
Material: R2/RA2 reflective overlay on aluminium composite backing
5.8.1. The sign to diagram 622.7 (S3‑2‑19, see Figure 5‑18) should be used to give effect to an order prohibiting towed caravans. This might be used at hills or narrow roads unsuitable for towed caravans where an alternative route is available. It could also be used to prohibit towed caravans being driven on unsuitable roads (e.g. narrow village streets or residential areas) close to a touring caravan site. If appropriate, the sign may have supplementary plate legends specified in S3‑3‑8 (time period) and S3‑3‑15 (exceptions).
