Regulatory, Lane & Parking SignsStandalone practice
A sign at the intersection reads NO TURN ON RED. You face a circular red light and want to turn right. What should you do?
Correct answer: Stop and wait for a signal permitting the turn.
Why
Obey the posted NO TURN ON RED restriction. Wait for a signal that permits the turn, then yield as needed and follow lane-use controls. The ordinary circular-red exception does not override a prohibitory sign.
