But the left-turn phase is protected-permissive, so what about it risks creating the yellow trap?
The opposing left turn is permissive-only. So if the controller didn't go to all-red when backing up to re-service the protected left turn phase, then opposing left turners could get trapped.
@@WestCoastTrafficSignals ah, that would do it! Thank you!
