No turn on red sign
A regulatory sign reading NO TURN ON RED. At that intersection, turning while the signal is red is not allowed.
How to read it
In most places a right turn on red is allowed after stopping, where no sign says otherwise, as California's and Florida's handbooks describe. This sign takes that permission away at one intersection. It covers right turns on red, and left turns on red from one one-way street onto another, and it stands near the signal head it applies to. The MUTCD has a symbol version (R10-11), with a red signal ball, and word versions (R10-11a and R10-11b).
Rules vary by state and country. This explains the sign's standard meaning in the U.S. Manual on Uniform Traffic Control Devices; it isn't legal advice.
Why one is posted
The MUTCD lists the conditions under which an engineering study might call for one, among them poor sight distance to approaching vehicles, an exclusive pedestrian phase, and more than three right-turn-on-red crashes reported in 12 months on that approach.
