MUTCD-CA G21-3 (California) Road Sign T-Shirt Design
This t-shirt features the iconic design of the G21-3 (CA) road sign, a critical piece of infrastructure on California's freeways. The artwork directly replicates the sign's layout, providing a clear visual representation of lane assignment and directional information.
Design Elements and Meaning
The central element of the design is a lane-assignment diagram. This diagram visually depicts lanes and their corresponding destinations. The words "RIGHT LANE" and "LEFT LANE" are prominently displayed, positioned above arrows pointing in specific directions. These arrows, along with accompanying route information (e.g., "North" and "South" or freeway designations like "INTERSTATE 5"), convey clear guidance to drivers.
The design utilizes a standard color palette used on highway guide signs: typically a dark background with white and possibly green or blue text and symbols. This color scheme ensures high visibility and recognition, even at a distance. The overall design prioritizes clarity and legibility, reflecting the sign's primary function of conveying essential directional information in a high-speed environment.
Symbolism
The G21-3 (CA) sign symbolizes efficient traffic management and safe navigation. It represents the California Department of Transportation's (Caltrans) commitment to providing clear and concise guidance to motorists. By clearly indicating lane assignments and destinations, the sign promotes smoother traffic flow, reduces driver confusion, and ultimately, enhances safety on California's roadways. The shirt design serves as a tribute to this important piece of public infrastructure.
