UK regulatory signs: signs that give orders
Regulatory signs tell you what you must or must not do. Most of them are circular, and you must obey them.
Know your traffic signs, the Department for Transport’s guide, says most regulatory signs are circular. A red ring or red circle means a prohibition, something you must not do. A blue circle generally gives a positive instruction, something you must do, or shows a route only for certain vehicles.
There are two notable exceptions: the eight-sided STOP sign and the downward-pointing triangle of GIVE WAY. Some rectangular signs give orders too, such as one-way traffic. Rule 109 says you must obey signs that give orders.
