Get clear, practical answers to the most common questions about the RTS-003 - 4 Aspect Traffic Signal with Green Left Turn road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the Irish driving theory exam in Ireland.
The RTS-003 sign indicates a traffic signal that has at least four aspects, and importantly, includes a specific green signal, often displayed as an arrow, allowing vehicles intending to turn left to proceed. It's crucial to observe the signal aspect relevant to your lane and intended movement.
Yes, you can turn left when you see a green left turn arrow, provided you are in the correct lane for that turn and the way ahead is clear of pedestrians and other vehicles. However, you must still be aware of oncoming traffic if you are turning across their path and yield if necessary, unless the arrow indicates a fully protected turn.
If you are proceeding straight ahead or turning right, you must obey the main traffic signal aspects that apply to your lane. Do not assume the green left arrow applies to you. Wait for the signal that permits your intended movement, and never proceed against a red signal.
In Ireland, like elsewhere, these signals are designed to manage traffic flow efficiently and safely. Pay close attention to any filter arrows, bus signals, or cycle signals that might be displayed alongside the main signal head, as they can have different rules. Always match the signal to your specific road user type and lane.
A common trap is assuming that any green signal means immediate, unimpeded movement. Learners sometimes forget to check if the way is clear or fail to identify the specific aspect that applies to their lane. Another mistake is not understanding that a green arrow usually permits movement, but 'clear ahead' and yielding to pedestrians or priority vehicles are still essential.
