Traffic light questions are one of the easier categories, but don’t skip them. Limerick’s drivers encounter traffic lights daily, and the theory test includes tricky questions about flashing amber lights, filter arrows, and the correct sequence.
Limerick’s driving conditions include a busy city centre with multiple bridge crossings over the Shannon, the Dock Road dual carriageway, and suburban estates. The Limerick Tunnel and approaches require understanding of motorway-style driving rules. Outside the city, the N21 to Newcastle West and N69 to Foynes have significant heavy vehicle traffic. Rural roads in south and east Limerick are narrow with poor visibility at junctions.
Traffic light questions are one of the easier categories, but don’t skip them. A few specific questions about light sequences and less common signals catch people out.
Key knowledge: The sequence is green → amber → red → red+amber → green. Flashing amber means proceed with caution (commonly at pelican crossings after the red phase). A green arrow filter allows movement in that direction only. You must stop on amber unless it’s unsafe to do so (you’re too close to the line).
Study approach: This is a quick category to master. Learn the light sequence, understand filter arrows and flashing ambers, and you’re most of the way there. A single focused practice session should be sufficient.
Common trap: What to do at a flashing amber light. Many people treat it like green, but the correct answer is to proceed only if the way is clear — pedestrians may still be crossing.

Limerick has two test centres: Limerick city (14-week wait) and Abbeyfeale (5-week wait). Abbeyfeale is a good alternative for shorter waits.
Limerick city has a 14-week wait. Abbeyfeale on the Kerry border has only a 5-week wait.
