Regulatory Road Sign (R10-11a)
No Turn on Red Sign Meaning & Driving Rules
The No Turn on Red sign (MUTCD R10-11a) revokes the general legal permission to turn right (or left from one-way to one-way) after stopping during a red traffic light phase.
Required Driver Action & Right-of-Way Protocol
Come to a complete stop behind the limit line and remain stationary until the traffic signal turns solid green.
Detailed Overview & Purpose
While right turns on red after a full stop are legally permitted by default in all 50 states, the No Turn on Red sign establishes an explicit local prohibition. It is installed at intersections where sightlines to oncoming traffic are blocked, where high-speed cross-traffic exists, where pedestrian crosswalk activity is heavy, or where light rail trains cross.
Key Standard & Origin: Right turn on red was legalized nationwide under the 1970s Energy Policy and Conservation Act to reduce fuel consumption, but local safety overrides require this sign.

Mounted adjacent to traffic signal heads on intersection mast arms and corner signal poles.
Common Driver Mistakes to Avoid
