PBOT Road Sign R6157 (Oregon) T-Shirt: Design Overview
This t-shirt showcases the design of the Portland Bureau of Transportation (PBOT) road sign R6157, a regulatory sign used in Portland, Oregon. The design faithfully replicates the visual elements of the official sign.
Artwork and Visual Elements
The artwork centers around a clean, bold design characteristic of regulatory road signs. The primary visual element is the text: "TRUCKS OVER 50 FT. USE TILLAMOOK + [up arrow]". The text is rendered in a black, sans-serif font, typical of road signage, providing maximum legibility.
The text is placed against a solid white background, adhering to the standard "BLACK/WHITE" format for regulatory signs. This color scheme immediately identifies the sign's function as providing specific instructions that must be followed. The design maintains a similar aspect ratio to the original sign – rectangular shape with a horizontal orientation. The up arrow is another primary element, which means “straight ahead.”
Meaning and Symbolism
The design clearly communicates a specific regulatory instruction: it directs trucks exceeding 50 feet in length to utilize the "Tillamook" route. The "+ [up arrow]" indicates trucks should go straight, using the designated Tillamook route.
The design, through its use of standard road sign typography and color, symbolizes authority and the need to comply with local traffic regulations. It serves as a visual reminder of the city's infrastructure and traffic management system.
