Agree. However, in certain lighting conditions (such as bright sunlight),
white anything can glare and become illegible. And a low afternoon sun angle
(azimuth) hitting a jumbotron becomes very difficult to see.

Jay, you might want to check with your state's department of transportation
for format guidelines and research on transportation signage (not
informational signs, such as "Next Exit, New York City, but traffic
signage).

Karl, so glad you got your research trip across the country paid by the
client/employer (grin), but that research has been available for several
decades, as well as typefaces (it's "Highway Helvetica" in bold and
semi-bold weights). US Department of Transportation might also have
guidelines, especially for US Interstates and highways.
