FHWA Series fonts


The FHWA Series fonts (often informally referred to as Highway Gothic) are a set of sans-serif typefaces developed by the United States Federal Highway Administration and used for road signage in the U.S. and Canada. The fonts were created to maximize legibility at a distance and at high speed, growing out of research by the California Department of Transportation. They are officially defined by the FHWA's "Standard Alphabets for Traffic Control Devices", originally published in the late 1950s. Changes to the specifications were published in 1966, 1977, and 2000. The 2000 specifications differ from earlier versions in the shapes of a few letters.
