MUTCD-CA SW48 Open Text (California) Road Sign T-Shirt Design
This t-shirt design features the iconic visual elements of the MUTCD-CA SW48 road sign, a special warning sign used in California. The core of the design replicates the sign's critical message: "TRACTOR-SEMIS OVER (X FEET) KINGPIN TO REAR AXLE NOT ADVISED."
Visual Elements & Meaning
The design adheres to the standard warning sign shape and color scheme mandated by California's traffic regulations. It presents a bold, black text on a bright yellow diamond background. The use of yellow signals a warning, indicating a potential hazard or condition requiring drivers' attention.
The central text, rendered in a clear, easy-to-read font, provides essential information. It warns tractor-semi truck drivers that if their kingpin-to-rear-axle measurement exceeds the specified value (indicated by "(X FEET)"), they are advised against proceeding. This advisory message highlights a potential hazard related to roadway geometry, turning capabilities, or infrastructure limitations, encouraging drivers to make informed decisions for safety and efficiency.
The design clearly communicates an advisory warning to drivers of large vehicles, advising caution in specific areas due to potential road constraints or hazards.
