Mandatory Sign
Mandatory signs are road signs which are used to set the obligations of all traffic which use a specific area of road. Unlike prohibitory or restrictive signs, mandatory signs tell traffic what it must do, rather than must not do. Most mandatory road signs are circular, may use white symbols on a blue background with white border or black symbols on a white background with a red border, although the latter is also associated with prohibitory signs.
