Roadgeek 2005 Series 6B by Michael D. Adams is a free heavy sans serif with broad, practical forms. Its full curves meet firm straight strokes in a sturdy, compact silhouette. The lettering feels direct and functional rather than severe.
Transportation and civic themes provide the clearest context for this design. It suits wayfinding signs, transit branding, and museum displays because the plain shapes recall public information graphics. Posters and editorial features on roads or cities share the no-nonsense voice.
