2009 Edition Part 6 Figure 6F-2. Methods of Mounting Signs Other Than on Posts
The fourth example shows an orange diamond-shaped sign with a black border and letters with the words "UTILITY WORK AHEAD" in three lines mounted on a vertical pole that is mounted on four horizontal supports. The distance from the bottom of the sign to the bottom of the supports is labeled as "1 ft MIN. above the traveled way." At the top of the sign, three orange flags are shown mounted equidistant apart from each other on short staffs that extend out from the top of the vertical pole at 45-degree angles.
Compliance
Section 6F.48 Reverse Curve Signs (W1-4 Series)
Guidance
In order to give road users advance notice of a lane shift, a Reverse Curve (W1-4, W1-4b, or W1-4c) sign should be used when a lane (or lanes) is being shifted to the left or right. If the design speed of the curves is 30 mph or less, a Reverse Turn (W1-3) sign should be used.
Standard
If a Reverse Curve (or Turn) sign is used, the direction of the reverse curve (or turn) shall be appropriately illustrated. Except as provided in Paragraph 3, the number of lanes illustrated on the sign shall be the same as the number of through lanes available to road users.
Transportation engineers may find this answer acceptable since they have a deeper understanding of the MUTCD than most, but not everyone has this knowledge. Luckily, definitions of these terms are provided to help make some sense of what they are trying to convey. Here’s how the MUTCD defines each of those types of roadways:
"Conventional Road" is a "street or highway other than a low-volume road, expressway, or freeway."
"Low-Volume Road" is a facility lying outside of developed areas of cities, towns, and communities, which serves fewer than 400 vehicles per day on average. A low-volume road shall not be a freeway, an expressway, an interchange ramp, a freeway service road, a road on a designated State highway system, or a residential street in a neighborhood.
"Expressway" is a divided highway with partial control of access.
"Freeway" is a divided highway with full control of access.
Still confused? It's not just you. Generally speaking, if the road is a divided highway with a concrete barrier or median, a 48 × 48″ sign will be required. A 36 × 36″ sign can be used on all other types of roadways.
