A UK traffic sign, diagram 106 of the The Private Crossings (Signs and Barriers) Regulations 1996. It would be mounted on crossing gates, to enable motorists to see the gate when closed across a roadway.
Regulations called for the sign to be 600 millimetres (24 in). This black and white version recreates the image as depicted in the law, but was not how the sign was intended to be posted.
Drawn according to The Private Crossings (Signs and Barriers) Regulations 1996 and RSSB standards.
