To regulate the flow of traffic.
The UK Highway Code does not show diamond shaped traffic signs because they are not authorised as legal road signs in the UK.
In the UK it is an emergency diversionary sign for motorways and primary routes.
I'm pretty positive Diamond shapes signs are warning signs.
Rectangular or square.

To regulate movement of traffic - ultimate drivers answer (ontario, Canada) are you sure
WHAT icons? If you are referring to the SHAPE of the signs themselves, the shape of the sign itself signifies the type of information the sign conveys. (e.g.: Octagaonal signs are ALWAYS stop signs - Diamond-shape signs ALWAYS convey some type of warning message - etc).
The black octagon is significant in traffic signs as it is used exclusively for stop signs. This shape and color combination is easily recognizable by drivers, indicating the need to come to a complete stop at an intersection for safety and traffic control purposes.
US standard traffic warning signs are yellow background with black symbols or letters. Traffic warning signs in other countries are generally white or yellow background with a red or black border in a triangular shape. Industrial warning signs are various colors, including OSHA and ANZI standards with orange background and black lettering. A yellow OSHA or ANZI sign would mean "caution" not "warning".
Answereach shape means something,eight sided means stop and so on unfortunitly I forgot the rest but you can get them from your MVB.
