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 sign indicates a traffic light system with multiple aspects, including a green signal specifically for buses. It means you must pay close attention to the signal that applies to your specific lane or movement. You should only proceed when the signal allowing your movement is displayed and the path ahead is clear.
The most crucial rule is to match the signal aspect to your lane, vehicle type, or crossing movement. Do not assume all signals are the same for every driver. You must wait if the signal does not permit your specific movement, even if other signals are green.
A common trap is assuming all signals apply to you. Learners might be confused by filter arrows, bus-only signals, or pedestrian signals and proceed incorrectly. Always check what signal applies to your situation before moving off, especially if you are not in a bus lane. Ensure the way ahead is clear.
No, you must not proceed if the green light is specifically for buses or another movement that does not apply to you. The RTS-003 is a multi-aspect signal, meaning different lights control different movements. Wait for the signal that is intended for your lane and direction of travel.
