RTS-003 - 4 Aspect Traffic Signal with Green Bus Irish road sign meaning

The RTS-003 4 Aspect Traffic Signal with Green Bus is a complex traffic light system designed to manage specific traffic movements, vehicle types, or signal sequences. You must obey the specific aspect that applies to your lane or vehicle, which may include special signals for buses. Always ensure the way ahead is clear before proceeding when your signal permits movement.

Interpreting the 4 Aspect Traffic Signal with Green Bus (RTS-003)

Mastering the 4 aspect traffic signal with a green bus is crucial for your Irish Driver Theory Test revision. This explanation helps you recognise its specific meaning and interpret its aspect correctly to ensure safe passage and compliance with traffic rules on Irish roads.

Definition of RTS-003

Traffic signals regulate priority where conflicting movements cannot safely proceed together. This signal display may apply to general traffic, turning traffic, buses, cyclists, pedestrians, or railway crossings depending on its symbol and position. Always match the signal to your lane and road-user type, then proceed only when the signal permits it and the way ahead is clear.

Meaning of RTS-003

4 Aspect Traffic Signal with Green Bus controls a specific traffic movement, crossing, lane, vehicle type, or signal sequence. Drivers must obey the aspect that applies to them and wait when the signal does not permit movement.

Allowed actions for RTS-003

Obey the aspect that controls your lane, vehicle type, or crossing movement.Move only when the signal permits it and the way ahead is clear.Prepare for amber, filter arrows, and protected movements to change the priority order.

Prohibited actions for RTS-003

Do not pass a red signal or a signal that does not apply to your lane or movement.Do not move on an arrow, bus, cycle, or pedestrian signal unless it applies to you.Do not block the junction or crossing while waiting for the signal sequence.

RTS-003 - 4 Aspect Traffic Signal with Green Bus road sign FAQ

Get clear, practical answers to the most common questions about the RTS-003 - 4 Aspect Traffic Signal with Green Bus 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.

What does the '4 Aspect Traffic Signal with Green Bus' (RTS-003) mean?

The RTS-003 traffic signal has multiple aspects (lights) to control different traffic flows or vehicle types, including a specific green light for buses. You must pay attention to the signal relevant to your lane or vehicle and follow its instructions precisely. Wait for the signal to indicate you can proceed.

How should I react when I see the RTS-003 signal?

You must obey the specific aspect of the RTS-003 signal that applies to your lane and vehicle type. If it's a general traffic light, follow the standard red, amber, and green. If there's a dedicated bus signal, only proceed on the green bus signal if you are a bus. Always wait for a permissive signal and ensure the junction or crossing is clear before moving off.

What are common mistakes learners make with traffic signals like RTS-003?

A common mistake is not paying attention to specific aspects like filter arrows or bus signals, or assuming the main signal applies to them when it doesn't. Learners might also move on an amber light when they could have stopped safely, or proceed into a blocked junction. Always match the signal to your situation.

Does the green bus signal mean all traffic can go?

No, the green bus signal on the RTS-003 is specifically for buses. If you are driving a regular car and see only the green bus signal illuminated, it usually means you must wait, as it does not apply to you. Always look for the signal aspect that governs your specific lane or vehicle type.

What if there are filter arrows or other special signals with RTS-003?

The 'Additional notes' highlight that filter arrows, bus signals, cycle signals, and pedestrian signals can operate independently of the main signal head. You must read and obey the specific symbol that applies to your movement or vehicle. For example, a filter arrow might permit a turn while the main signal is red for straight-ahead traffic.
