| Clearview-Bold (left position, original
version of typeface) improves nighttime sign reading distance by up
to 16% compared to the existing road sign typeface FHWA E-modified (right).

easily translate into 80 extra feet of reading distance, or a substantial
1.2 seconds of additional reading time. |
