When encountering a straight ahead green filter light and a red light while turning right, is it necessary to wait for the right filter light if the junction is clear of oncoming traffic?

When faced with a straight ahead green filter light and a red light while turning right, the necessity to wait for the right filter light is generally rooted in ensuring safety and compliance with traffic signals. Even if the junction appears to be clear of oncoming traffic, the red light indicates that vehicles in that direction are still required to stop. The presence of the green filter light does not override the red light's command to stop; instead, it only allows movement when it is safe to do so, which includes adhering to all signals in operation.

This approach ensures that drivers are consistently checking for any potential hazards and following the rules laid out by traffic signals. Additionally, it promotes the orderly flow of traffic, preventing accidents that could arise when one assumes it is safe to proceed without following the signals as they are intended to be observed.

Other choices may imply a disregard for traffic signals, which could lead to confusion and unsafe driving practices. In this scenario, the importance of patience and sound judgment while driving cannot be overstated, thus making waiting for the right filter light the correct action to take.
