Orange indicates road construction or
maintenance. You'll want to slow down
when you see an orange sign, as part of
the road may be closed off or torn up.
And there may be workers and
maintenance vehicles around, too.

Brown signs point out recreation areas
or points of historic or cultural interest.

Signs
The shape of the sign will tell you
something, too.
An octagonal (eight-sided) sign means
Stop. It is always red with white letters.
A triangle, pointed downward, indicates
Yield. It assigns the right of way to
traffic on certain approaches to an
intersection.
A diamond-shaped sign is a warning of
something ahead-for example, a curve,
steep hill, soft shoulder, or a narrow
bridge.
A triangular sign also is used on two-
lane roads to indicate a No Passing
Zone. This sign will be on the left side
of the roadway.
