Priest:
not quite sure why you straddled two lanes if you did not intend to turn left? Also it appears you left too much room on you n/s if two cars could get in. Or am i missing something?
Straddled the 2 lanes as a sharp left onto the roundabout is required and yes I didn’t take enough of the nearside lane as a car in front on the very inside lane stopped as soon as the light turned amber instead of carrying on as he was committed which took that extra bit of space which would have took the trailer over more . Having said that London traffic will squeeze up the inside of you with a ■■■ paper between them and you if they can .
Good point made re indicating left from the word go even when not turning left as here just to warn those who are unaware of the trailer movement .
