What does the No Turn On Red sign mean?
The No Turn On Red sign (MUTCD R10-11) is a regulatory sign under the federal Manual on Uniform Traffic Control Devices, the national standard the states build from. Stopping does not buy the turn here. Where the default rule would let you go right on red after a full stop, or left on red from one one-way street onto another, this sign cancels the permission until the light turns green.
