Is waiting on roundabout a fail in the test?Watch this thread
Then move over to the left when it’s safe to do so.
Waiting in the middle then trying to change lane, whilst there are cars behind you, is an automatic fail on the test.
1 Accelerate if it's safe to open up a space for you to move over
2 Allow the other driver to pass before you move over (but on no account stop or loiter in the roundabout)
3 Exit into the right hand lane if there is one then go back to the left as soon as it's safe
4 Go around the roundabout a second time
Any of these would be acceptable, but you can avoid having to make these decisions by making sure that keep up enough progress so that drivers are not tempted to come up your inside in the first place. Also, make sure that you use your mirrors early enough to give you the time to judge and make sure that your exit signal is properly timed - https://www.ukdrivingskills.co.uk/le...-a-roundabout/
