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.
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.
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.
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.
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.
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.
