Black, Yellow, Green, Blue, Orange, Brown: Know What Each Type Of Road Signs Mean

Road signs can come in many colours and shapes, and keeping tabs on each individual colour can be challenging. But studying your traffic signs and knowing what each kind of road sign signifies could be the difference between arriving safely or not.

What are Traffic Signs?

If you travel considerably, it’s unlikely that you encounter transportation signs during your commute. Road signs are utilised as a method of warning and guiding drivers, helping to regulate the flow of traffic among vehicles, pedestrians, motorcycles, bicycles and others who travel the streets, highways and other roadways.

The traffic signs are for the public’s protection and must not be missed or ignored. Furthermore, signs that direct drivers and parking attendants must be prominent enough to get the attention of drivers and guide them to an absolute destination. Road signs, as well as road signs, use the same shape, colour, and symbol to reinforce a consistent message.

Here are some tips to improve your knowledge of traffic sign colours:

Black and white

Signs displaying regulations (i.e., speed limits) are posted on white or black signs. Regulatory signs tell you about what can and you can’t do on the road. Some signs display maximum and minimum speed limits for all kinds of vehicles on freeways and restricted access highways. In construction and maintenance areas, posted speed limits divide the legal maximum speed along that particular section of the road. Unless necessary for safety, driving slower than the minimum is illegal.


If a traffic sign is yellow or yellow-green with black writing or symbols, this means slow down, drive cautiously, or generally be aware of your surroundings.


This colour is used for guide signs. These signs inform you where you are, which direction to go, and how far you must go.


This colour is also used for directional signage along roadways. These signs inform you about services beside roads such as rest stops, healthcare facilities, gas stations, and lodging.


Orange traffic signs will be visible wherever you visualise construction activities. This colour indicates to drivers that there may be hazards on the horizon due to active construction projects. Slow down and thwart oncoming cars, since workers may be directing traffic.


This colour is used for park and recreation signs. Traffic signs are necessary whenever we want to keep all drivers safe. Different colours signify different actions or references, but every road sign is important in its own right. If you get confused about a particular coloured traffic sign, take some time to review the advice it supplies.


You can’t really go wrong by paying close attention to the traffic signs and following the signs directions. You’ll save yourself from tickets and possible accidents. Memorising this list means that you will be able to easily recognize the difference between a speed limit sign and a stop sign, as well as an intersection warning sign and a railroad crossing sign.
