When can you make a turn on red if there is a "No Turn On Red" sign?

Making a turn on red is prohibited when there is a "No Turn On Red" sign present. This sign clearly indicates that the intersection requires vehicles to stop and wait for a green signal before making any turns, thereby ensuring the safety of pedestrians and other drivers. Disregarding this sign can lead to accidents and is a violation of traffic laws. Therefore, turning when such a sign is posted is not permissible under any circumstance, ensuring compliance with traffic regulations and promoting road safety.
