Lane-control lights are a specific type of traffic light used to manage traffic on a multi-way road, highway or tollway. Typically, these lights allow or forbid traffic to use one or more of the available lanes by the use of green lights or arrows (to permit) or by red lights or crosses (to prohibit).
The definition of a blazon is a coat of arms, or a showy display. An example of a blazon is a family crest. Blazon means to proclaim or portray. An example of blazon is for the town crier to make an announcement.
Much of the printed design for a given coat of arms is more the artist's preference or the style of a particular herald, and not a part of any particular blazon. The mantling and the banners for names and mottoes, for example, are not an official element of the blazon of arms.
