What do black and white traffic signs mean?

When driving down any public road in the United States, you will see a lot of different signs. There are different categories of signs, and each category will typically have a set color scheme to help drivers quickly identify their meaning. Black and white traffic signs are almost always going to provide drivers with regulations in that specific area regarding how they must drive.

Speed Limit Signs

The most common example of a black and white traffic sign is the speed limit sign. This will let drivers know the speed at which they should be traveling. Anyone who is found to be exceeding the speed limit will be subject to getting pulled over and ticketed.

Directional Signs

If a lane is closing, a sign may indicate to keep left or merge right depending on the situation. These types of signs will typically be in black and white. If the closing is due to construction, there may be an orange sign to show the construction is starting, and a black and white one to give the instructions.

Passing Signs

Signs that let drivers know when they can pass slower traffic should also be in black and white. These are very common on two lane roads where there are not a lot of lights or stops. In these situations, faster drivers need to cross into a lane for oncoming traffic in order to pass. The signs help ensure a driver only does this in an area where it is safe.

There are many other signs that will be black and white, all of which should provide clear instructions to drivers to help ensure they are following the local regulations. Black and white signs are typically easy to read because of the high contrast, and even during the night they can be seen clearly thanks to reflective materials that are used.
