MUTCD-CA R20D-4 (California) Road Sign T-Shirt Design
This t-shirt design prominently features the iconic elements of the California R20D-4 road sign, a critical piece of traffic regulation in the state. The design replicates the standard format of a regulatory sign, instantly recognizable to drivers and those familiar with traffic control devices.
Visual Elements and Symbolism
The core of the design is the distinct rectangular shape, framed by a bold black border, a defining characteristic of regulatory signs. The background is a clean white, providing maximum contrast for the black text and numerals.
At the top, the sign reads "ON BRIDGE", immediately conveying the location where this regulation applies. Below, the message is further clarified with "FOR VEHICLES OVER 10 TONS", clearly indicating the target group affected by the restriction. Below that, the speed limit "15 MPH" is clearly displayed. The numbers and text are in a bold, easily legible font, essential for quick comprehension by drivers.
The overall design is a direct representation of a vital traffic control sign, serving as a reminder of bridge weight and speed restrictions designed to protect infrastructure and ensure safety.
