Measured against the rulebook

Pixel-level verification found four places where FHWA's published SVG exports differ from the primary PDF artwork. mutcd-ts corrects each conversion defect and matches the primary shapes exactly.

Zoom of the Stop sign's S in FHWA's published SVG, showing a flattened, boxy upper-left shoulder
FHWA's published SVG: boxy S shoulder
Zoom of the Stop sign's S in the primary PDF artwork, showing the correct round shoulder
Primary PDF and mutcd-ts: round shoulder
Pixel diff between the published SVG and the primary PDF: an orange sliver marks where the SVG deviates
Pixel diff: orange = SVG deviates from PDF
