PBOT Road Sign R4022 (Oregon) T-Shirt: Design Overview

Visual Representation

This t-shirt design features a faithful representation of the Portland Bureau of Transportation (PBOT) road sign R4022. The design adheres to the standard regulatory signage color scheme: black lettering and symbols against a white background. This stark contrast ensures high visibility and immediate recognition.

Design Elements and Meaning

The central element of the design is the text "STOP HERE ON RED". This text is the primary message of the sign, clearly indicating the action required of motor vehicles at a signalized intersection. Beneath this, the addition of "[left diag. down arrow]" visually guides the viewer to the correct stopping location, usually a stop bar or designated stopping point, which is the heart of the design.

The design also incorporates the crucial "EXCEPT BICYCLE" exception. This critical detail, implied by the inclusion of the sign's full wording in the description, signifies a key difference in how bicycles are treated at this specific intersection. This indicates a bicycle-friendly feature.

Symbolism

The design, as a whole, embodies the purpose of the sign: to regulate traffic flow while accommodating bicycle traffic. The arrow symbolizes guidance, indicating the exact place where motor vehicles must stop, and the overall design promotes traffic safety and clarity for all road users.
