This
paint seems to be popular with
UDOT of
Utah. It's completely
invisible after
dark because it's
not reflective. Certain
roads are
impossible to drive at
night - they
curve, and with
oncoming traffic you can't tell
where the
road is curving because all you can
see are
headlights; the
paint dosen't
reflect any
light back.
We can't use the
reflective dots because the
snowplows would
kill them every
winter.
