Ahh yeah there's not many markings there and they're all faded..
If you're coming from the Ricoh -Blue ribbon island is left lane if you're going up longford road, left lane & middle lane if you're going towards Gallagher and right hand lane if you're going down foleshill road.

Ricoh island is the same left to turn into the Ricoh, left and middle to go straight on towards Tesco and right lane if you're going towards exhall/prologis park

If you're going round the island and back on yourself stay in the right hand lane and move across to the middle when your exit comes up

Hope that explains it a little better for you hun xx

It depends how many lanes the roundabout has.. Where about is your instructor making you practice hun? Bayton road? X

General rule of thumb, unless signs or road markings indicate otherwise you use the left lane for left & straight on, right lane for right hand turns

There's a roundabout near me where nobody seems to have a clue, it has 5 exits if you include going back the way you came from & I often see people use the left lane to take an exit to the right (sometimes undertaking cars in the right lane), or the right lane to go left 🤔

Did you not given a book from instructor with any of it in ?if not you tube is greatxxxx

Or YouTube might be best as you’ll have a visual x

Highway Code website aswell x
