If there's a "no turn on red" sign, when can you legally make a turn on red?

Answer: C — NEVER

The indication of a "no turn on red" sign means that drivers are prohibited from making a right turn at that intersection when the traffic light is red. This rule is in place to prevent accidents and ensure the safety of pedestrians and other vehicles who may have the right of way. Drivers must adhere to the "no turn on red" sign at all times, which is why the only acceptable response is to not turn on red at all, reinforcing the importance of following traffic signs and signals for safe driving practices.
