Which retroreflective material is used with Wrong Way Signs?
High-intensity prismatic sheeting meets federal minimum retroreflectivity requirements, but some states require the more reflective full-cube prismatic sheeting on their state roads.
How are Wrong Way Signs mounted?
All three sizes of Wrong Way Signs are mounted on a single post. Local jurisdictions may require round, square, or U-channel posts for your project.
What does a Wrong Way Sign look like?
All Wrong Way Signs are rectangles oriented horizontally. Each sign has the words “Wrong Way” written in all capital letters and in white text on a red background. There are two lines of text—the first line reads “wrong” and the second line reads “way”. There is a thin white border around the edge of the sign.
Where are Wrong Way Signs used?
Wrong Way Signs are often set up on one way streets, both sides of a divided highway, and on both sides of an interstate exit. On divided highways, Wrong Way Signs signal that drivers are travelling on the wrong side of the highway. In some cases, Wrong Way Signs can be optionally placed after Do Not Enter Signs for additional guidance.
When would I need a Wrong Way Sign vs. a Do Not Enter Sign?
Wrong Way Signs are used to alert drivers that they are traveling in the wrong direction, and, in contrast, Do Not Enter Signs primarily signal that entry is not allowed. In some cases, both signs can be used together—drivers will often see Do Not Enter Signs first and then see Wrong Way Signs placed farther down the roadway.
