Why learners fail their driving test on roundabouts

The one biggest reason learners fail a driving test when on roundabouts is to do with changes lanes without looking!

It is legal to change lanes whilst on a roundabout, but it can be very dangerous if you do not look in the direction you are changing lanes to, before you do it.

It's like shutting your eyes and crossing the road! YOU JUST WOULD'NT DO IT

If you switch lanes without first looking alongside you to see if there is another vehicle there, how would you know it is safe to do it?

If you don't look and just move across, there is every chance there is already some other vehicle in that lane, if you don't look how would you know?

If your approach to a roundabout happens to be the wrong lane, it is far safer to stay with that lane and go where it takes you, you can always come off the roundabout, find a side road and turn around and come back to the roundabout to take the correct exit next time.

The best advice, get the correct approach lane in the first place, and look further ahead to see where that lane is going so that you stay in your lane,
there will then be no need to change lanes at all.
