signal face displaying signal indications to permit or prohibit the use of specific lanes of a roadway or to indicate the impending prohibition of such use
NOTE 1 to entry: Typically, these are arrow displays of varying colours.
NOTE 2 to entry: This document does not attempt to use signal colours/indications to reflect the allowed vehicle operation, rather, the permitted movements are indicated and the state of the movement as explained later herein. Each region has unique mechanisms for using the display signals to indicate the movement(s) allowed.
