Bold, easy-to-read traffic control signs alert drivers to caution areas, regulations, services, areas of interest and more.

To make it easy for people to understand roadway sign meanings, the U.S. Department of Transportation (DOT) established a universal set of traffic sign guidelines. These guidelines help drivers quickly and accurately interpret road signs, even at high speeds. This is especially important considering language barriers and vision deficiencies that can complicate the interpretation of these important signs.

The shape of a sign can provide a clue about its message even before you can read the content. Different types of signs have different shapes. An octagon means stop. An upside-down triangle means yield. A diamond shape warns of possible hazards ahead. Pentagon-shaped signs indicate a school zone. Round signs indicate railroad crossings.

All traffic signs must now be reflective, according to the Federal Highway Administration. The signs come in three grades of reflectivity (technically named retro reflectivity as a measure of reflecting light back to its source); Type I Engineer Grade, Type IV High Intensity Grade, and Type XI Diamond Grade. This product conforms to USDOT FHA standard specifications for construction of roads and bridges on federal highway projects, 1985 FP-85, Type II, Section 718.01. The reflective sheeting is chemical resistant and can withstand temperatures up to 160°F.

In addition to color and shape, roadway signs must also meet specific size and material requirements set by the MUTCD. This ensures consistency and visibility. Retroreflective materials or lighting help illuminate signs that need to be visible at night.

Have you ever been confused by the meaning of a roadway sign or wondered about the significance of its color and shape? Understanding the meanings of traffic signs is crucial for drivers to ensure safety.
