and
guide the driver during day and night conditions. Pavement markings include striping,

.
Striping
Striping should be installed and maintained in accordance
with standards established by the Traffic Operations Division. As
a minimum, centerline striping should be installed on all paved
roads on the state highway system.
Temporary Markings
When not practical to stripe pavement repairs or areas where
striping has been destroyed by maintenance operations, on the same
day as the operation, temporary markings should be used as a short-term
measure. Usually permanent markings should be placed as soon as
practical. Temporary markings may be reflective tabs, tape or paint.
Pavement Graphics
Pavement graphics include stop bars, school zone crossings,
arrows, railroad crossing symbols and other lettering or symbols
painted or installed on the pavement. They should be installed and maintained
as soon as practical in accordance with standards established by
the Traffic Operations Division.
Raised Reflective Pavement Markers
Raised reflective pavement markers should be maintained as
soon as practical on all roadways in accordance with standards established
by the Traffic Operations Division.

The most effective and least expensive treatments are depressions rolled or milled into the pavement surface perpendicular to the roadway. Please refer to the for recommended placement guidelines.
