Specifies traffic control devices to be used to control and warn traffic at and in advance of railway level crossings. Significant changes incorporated in this revision include the addition of an optional red target board to the basic position (crossbuck) sign, new symbolic train and diagrammatic warning signs for passive control crossings, and a minimum treatment option for certain low volume crossings.

This Standard specifies traffic control devices to be used to control and warn traffic at and in advance of railway crossings. It specifies the way in which these devices are used to achieve the level of traffic control required for the safety of rail traffic and road users. Requirements and guidance are also given in appendices on the illumination and reflectorization of signs, on their installationand location, and on selection of the appropriate sign size.
