Figure 4D-13. Typical Positions and Arrangements of Shared Signal Faces for Permissive Only Mode Right Turns

This figure shows the typical positions and arrangements of shared signal faces for permissive only mode right turns. A legend shows a black arrow indicating the direction of travel on the roadway.

The figure shows two types of examples. The first example is labeled "A – Typical Positions." It shows two signals aligned horizontally on a horizontal pole over a vertical segment of three lanes of a roadway. An upward-pointing black arrow is shown in the left and middle lanes denoting the direction of travel as straight through, and a white right-turn arrow is shown marked in the right lane. The left signal is shown above the left lane as a vertical arrangement of circular red, circular yellow, and circular green signal indications. The right signal (noted as a shared signal face) is shown above the center lane as a vertical arrangement of circular red, circular yellow, and circular green signal indications. Below these signals, the word "OR" is shown and three more signals aligned horizontally on a horizontal pole. The left signal is shown above the left lane. It is shown as a vertical arrangement of circular red, circular yellow, circular green, and circular green signal indications. The middle signal is shown above the middle lane. It is shown as a vertical arrangement of circular red, circular yellow, circular green, and circular green signal indications. The right signal (noted as an optional signal face serving as a shared signal face) is shown above the right lane as a vertical arrangement of circular red, circular yellow, and circular green signal indications.

The second type of example is labeled "B – Typical Arrangements." It shows two arrangements. The left arrangement shows a vertical arrangement of three signal indications - circular red, circular yellow, and circular green. The right arrangement shows the same three signal indications arranged horizontally.
