So i decided to do a bypass completely on my own today. It was not my intention, but it just happened. The slip road joining the bypass is long so drivers can join the dual carriageway in plenty of time. I don't know what happened, but I stupidly thought this was a left lane, and continued down it until near the end, when i realised my error. I slowed down just before it ended, and someone behind slowed down and kindly let me join.
I am incredibly anxious about this being labelled as careless or dangerous driving. Please could someone help put my mind at rest? I stopped just before the solid white line, and it was just before the merge to the left road marking. As a new driver i am really worried about receiving penalties.
Thank you.
