Road signs

Here i will be explaining how road signs get across their message easily and how they convey the message they want. 

This Sign Works quite simply  by two lines connecting it shows that two lanes will be joining together. With the Red outlining the sign its self it helps to draw attention to the sign . this also helps highlight the importance of it. 

 this sign helps show its message with the red block at the end of the white line. White lines are established as roads in all road signs. The red shows that it could be dangerous and that it is not allowed . Red has been highlighted as important or dangerous for road signs as well.

Firstly this sign highlights its self with importance with its red ring, showing its serious and also imply's danger with its red this also helps bring attention to it. 

And the bold 30  automatically makes you think of the speed in my opinion.

The red may also make people slow down  if they are going to fast because they will only see red.
