Sign shapes and colours
The word or symbol on traffic regulation signs tell the driver what can or cannot be done at a specific location or time, and provide information. The shape and colour will vary depending on the type of message.
Traffic regulation signs include those that show right-of-way and road access that is permitted or prohibited. They also show control of speed, turns, direction of travel, passing, traffic lanes, parking and crosswalks.
