Clearview, also known as Clearview Hwy, is the name of a humanist sans-serif typeface family for guide signs used on roads in the United States, Canada, Indonesia, the Philippines, Israel, Brazil[2] and Sri Lanka. It was developed by independent researchers with the help of the Texas A&M Transportation Institute and the Pennsylvania Transportation Institute, under the supervision of the Federal Highway Administration (FHWA). It was once expected to replace the FHWA typefaces in many applications, although newer studies of its effectiveness have called its benefits into question.[1][3]

Initial testing indicated that Clearview was 2 to 8 percent more legible in both day- and night-time viewing than the then-dominant Series E (Modified) on overhead signs, particularly benefiting older drivers, with a 6 percent increase in legibility distance.[4] A design goal of Clearview was the reduction of irradiation effects of retroreflective sign materials.[4] Reduced nighttime overglow or haloing was expected also to improve recognition rates for computer road sign detection.[5] However, these tests also compared new signs in Clearview to existing, weathered signs in the existing Highway Gothic font.[6] The new font's apparent legibility "was more due to the fact that older, worn signs were being replaced with nice, fresh, clean signs which were, naturally, more legible." Better testing also revealed that legibility was worse for negative contrast signs (dark lettering on light backgrounds) such as on speed limit and yellow warning signs.[6]
