Roundabout questions are among the most commonly failed on the Irish theory test. The rules feel straightforward when you’re driving, but the theory test asks about them in ways that catch many learners off guard.
The Basic Rule
Give way to traffic already on the roundabout, approaching from your right. This is the fundamental rule, but the test digs much deeper.
Lane Selection
- Turning left (first exit): Approach in the left lane, signal left
- Going straight (second exit): Approach in the left lane (unless marked otherwise), signal left as you pass the exit before yours
- Turning right (third exit or beyond): Approach in the right lane, signal right, then signal left as you pass the exit before yours
Signalling on Roundabouts
This is where most people get caught. The test expects you to know:
- Signal right when approaching if turning right
- Signal left when you’re about to exit
- No signal needed when approaching to go straight ahead
- Always check mirrors before changing lanes on the roundabout
Common Theory Test Questions
Typical roundabout questions include:
- Which lane should you use for the third exit?
- When should you signal left on a roundabout?
- Who has right of way at a roundabout?
- What should you do if you miss your exit?
The answer to that last one: keep going around. Never reverse or stop suddenly on a roundabout.
Practise Roundabout Questions
Head to practice mode and filter by Rules of the Road to drill roundabout questions specifically. Then test yourself under exam conditions with a mock test.
