MUTCD R10-11: No Turn on Red Signs
The R10-11 sign is covered in Section 2B.60 of the Manual on Uniform Traffic Control Devices, 11th Edition. Below are the provisions from that section that describe when the sign is used and how it is placed.
What it means and when it is used
- Standard · Required (shall)Where a right turn on a circular red signal indication (or a left turn on a circular red signal indication from a one-way street to a one-way street) is to be prohibited, a NO TURN ON RED (R10-11, R10-11b) word message sign (see Figure 2B-28 ) shall be used. A NO TURN ON RED (symbolic circular red) (R10-11a) sign (see Figure 2B-28 ) shall be used when the approach is controlled by both circular red and red arrow…
- Guidance · Recommended (should)If used, the No Turn on Red sign should be installed near the appropriate signal head.
Placement and mounting
- Standard · Required (shall)If an R10-11, R10-11a, R10-11b, or R10-17a sign with conventional road size as shown in Table 2B-1 is used on an approach on the far side of the intersection and the distance between the stop line and the sign is greater than 120 feet, then a duplicate sign shall be located on the near side of the intersection to supplement the sign on the far side of the intersection.
- Option · Permitted (may)On signalized approaches with more than one right-turn lane, a NO TURN ON RED EXCEPT FROM RIGHT LANE (R10-11c) sign (see Figure 2B-28) may be post-mounted at the intersection or a NO TURN ON RED FROM THIS LANE (with down arrow) (R10-11d) sign (see Figure 2B-28) may be mounted over the approximate center of the lane from which turns on red are prohibited.
- Guidance · Recommended (should)Where turns on red are permitted and the signal indication is a steady RED ARROW, the RIGHT (LEFT) ON RED ARROW AFTER STOP (R10-17a) sign (see Figure 2B-28 ) should be installed adjacent to the RED ARROW signal indication.
