A turn restriction is a restriction based upon a vehicle manoeuvre. This type of restriction includes prohibitive driving instructions, mandatory driving instructions and implicit restrictions. Prohibited instructions are indicated by road signs within a red circle, examples include No U Turn, No Right Turn or No Left Turn. These can include exceptions to the instruction and are typically elements like Except for Buses. Mandatory driving instructions are indicated by road signs within a blue circle or painted on the roadway such as Turn Right, Ahead Only and No Left Turn. Implicit restrictions occur where a turn is not signed as prohibited but would not be a normal manoeuvre. For example, where a road splits around a traffic island or at complex junctions where additional geometry has been captured to reflect the traffic flow. These are not differentiated from actual signed restrictions.
