Section 4: Advisory Speeds
Anchor: #i1000207Advisory Speed Sign
An Advisory Speed sign (W13-1) is added to a warning sign to advise motorists that a speed lower than the speed limit should be considered. The use of this sign is discussed in the Texas Manual on Uniform Traffic Control Devices (TMUTCD) and in Procedures for Establishing Speed Zones.

- Anchor: #PRUVVLTO
- curves and turns (W1-1, W1-2, W1-3, W1-4, W1-5, W1-10 series, W1-11, W1-13 and W1-15) (see the following subsection) Anchor: #MUUNMGWA
- intersections (W2-1 through W2-8) Anchor: #RLLQUHEC
- narrow and one-lane bridges (W5-2 and W5-3) Anchor: #RIHWKCBS
- BUMP (W8-1) or DIP (W8-2) Anchor: #RNFHUXWP
- descending grades (hills) steeper than 5 percent (W7-1 and W7-1a) Anchor: #VQFWCNQT
- temporary traffic control zones Anchor: #PQXXYWJY
- other conditions, as necessary.
These warning signs and their uses are discussed in the TMUTCD and the Procedures for Establishing Speed Zones manual.
