Roadgeek 2005 Series 5B by Michael D. Adams is a free road-sign sans serif with the plain, direct build of functional public lettering. Its broad strokes, open rounded forms, and squared endings produce a clear, practical silhouette, with subtle changes in width keeping the letters from looking rigid.
Designers addressing drivers, travelers, or transport enthusiasts can use it for wayfinding signs and map graphics because the forms read as purposeful and familiar. It also suits route-themed posters, museum displays, and road-trip merchandise. The lettering can become part of a fictional highway system, turning names or route numbers into highly convincing sign elements.
