Section 2C.36 Advance Traffic Control Signs
Standard
- The Advance Traffic Control symbol signs (see Figure 2C-6) include the Stop Ahead (W3-1), Yield Ahead (W3-2), and Signal Ahead (W3-3) signs. These signs shall be installed on an approach to a primary traffic control device that is not visible for a sufficient distance to permit the road user to respond to the device. The visibility criteria for a traffic control signal shall be based on having a continuous view of at least two signal faces for the distance specified.
Support
- Permanent obstructions causing the limited visibility might include roadway alignment or structures. Intermittent obstructions might include foliage or parked vehicles.
Guidance
- Where intermittent obstructions occur, engineering judgment should determine the treatment to be implemented.
Option
- An Advance Traffic Control sign may be used for additional emphasis of the primary traffic control device, even when the visibility distance to the device is satisfactory.
- An advance street name plaque may be installed above or below an Advance Traffic Control sign.
- A warning beacon may be used with an Advance Traffic Control sign.
