Why Should You Learn the Basic Colors of U.S. Road Signs?

Colors and shapes are specified by the Federal Highway Administration and are National Standard, which means they are the same in all states.

Most states find shapes and colors important enough to be included in the driver’s manuals or driver handbooks. If they are included in your manual, you may also except questions about them to show up on the driver examination.

This, of course, is one reason for you to study both shapes and colors. But it is also a great help when you are driving later in life and looking for specific signs.

Identifying basic colors and shapes from a distance

Let’s say you are driving on an interstate and you have been behind the wheel for longer than you should. You desperately want to find a rest area.

By scanning the road far ahead and looking for blue road signs, you can be prepared and keep in the right lane when a rest area shows up – instead of finding yourself in the left lane overtaking a large truck when you get there.

Or if you are running out of gas. Look for blue signs ahead, they all indicate some kind of motorist service. If it isn’t a rest area, it is likely a sign that guides you to restaurants, gas stations, or lodging.

Orange signs ahead warn you of a work zone. By limit all distractions well ahead of the work zone you can be more alert to changing traffic patterns and workers.

Green signs guide you to different destinations. If you are driving on unfamiliar roads, it can be a good idea to stay in the right lane until you can read the information on the guide signs.

The above are just some examples when knowing the color of signs can come in handy.

  1. The colors and signs are important but the shades aren’t as I think. About shade questions confuse to examiners.

    • I suppose you mean shapes.

      United States have a different system than many other countries. So, if you’ve learned the shapes in another country, you need to study the American ones.
