MUTCD-CA SR39AU (California) Road Sign T-Shirt - Design
This t-shirt features the design of the MUTCD-CA SR39A(U) California Special Regulatory road sign. The sign is instantly recognizable by its bold, white background and black lettering, a standard design element of traffic signage for clear visibility.
Visual Elements and Meaning
The core of the design is the three-line legend: "LEFT OR U" / "TURN ON GREEN" / "ARROW ONLY". This text is rendered in a clear, sans-serif font, typical of road signage to maximize readability. The arrangement of the words conveys a specific traffic instruction.
The sign's purpose, and therefore the shirt's implied message, is to communicate a crucial traffic rule: left turns or U-turns are permitted only when a green arrow signal is displayed. The design symbolizes the restriction of turning movements to times when the path is clear of oncoming traffic, ensuring safer traffic flow.
The inclusion of "U" within the SR39A(U) designation, sometimes abbreviated on the sign itself, is a direct nod to the allowance of U-turns under the same green arrow conditions. This detail subtly differentiates the sign and shirt design for those knowledgeable of California traffic regulations.
