Hopefully my diagram uploads.
I was in a flow of traffic at traffic lights, when we turned green we set off. Further up the road ahead of me, a car was trying to turn right but was blocked from doing so because traffic on the other side of the road (now on a red light) had blocked their right turn. I didn't see this at the point I went through the green light. I had to come to a stop in the middle of the traffic light. When the other side then turned green, they couldn't move because I was in the way.
Cue lots of other drivers shouting and gesturing at me, I understand I was blocking the way but it wasn't deliberate /intentional and I couldn't have known the flow of traffic would stop,so couldn't have done anything about it.
I blamed the driver further ahead from blocking the road for the right turner. They blamed me. Is it just one of things where no one is really to blame?
Or AIBU? Is there a part of the highway code I need to brush up on? Should traffic lights be treated like box junctions and you shouldn't enter until your exit is clear?
