Roundabouts are the single most failed category on the theory test. Limerick has plenty of them, and 7,200 learner drivers need to know lane positioning, signalling, and right of way. Get these right and you’ll avoid the most common test mistakes.
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.
Roundabouts are the single most-failed category on the theory test. The questions test lane positioning, signalling, and right of way — and the correct answers aren’t always intuitive.
Key rules to master: Traffic already on the roundabout has right of way. Left lane for turning left or going straight. Right lane for turning right or doing a U-turn. Signal left when passing the exit before yours. On mini-roundabouts, the same rules apply but with less physical space.
Study approach: Draw roundabouts and trace your path for each exit. Visualising the movement makes the signalling rules click. Then practice with L-Plate’s roundabout questions until you’re scoring 90%+ consistently.
Common trap: When to signal on a roundabout. Many people signal right when entering (wrong for going straight) or forget to signal left when exiting.
Q1.Who has right of way at a roundabout?
Q2.Which lane should you use for turning right at a roundabout?
Q3.When should you signal on a roundabout?
These are just a sample. L-Plate has all 45 roundabout questions with AI-powered explanations.
Traffic already on the roundabout has right of way
Left lane for straight ahead or left turns
Right lane for right turns or U-turns
Always signal when leaving a roundabout

Traffic on the roundabout has right of way. You must yield to traffic approaching from the right. Signal when leaving.
Left lane for 1st and 2nd exits (straight/left). Right lane for 3rd+ exits (right/U-turn). Always check signs.
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.
The RSA question bank contains 45 roundabout questions. On any given test, you’ll typically see 3–12 questions from this category depending on the random selection.
The national average pass rate for roundabout questions is 62%. Practising all 45 questions on L-Plate significantly improves your chances.
