Hi.

I have been flashed on the M1 going under a red X closed lane past a camera. Thing is, I couldn't safely move out in time. When joining the motorway, I wasn't going to dash across two lanes so I joined, then when I wanted to move again, there was a car on my right so couldn't. The car got next to me right before the red X (speed limit was 40) and I slowed to 30 to move out but I did this after I passed the X. Then right as I started moving out of my lane, I got flashed. I also saw many other flashes in my rear view mirror so likely others got cought out doing the same thing. I have now received my options: Motorway Awareness course or £100 fine and 3 points. Thing is, I don't feel it's right. I want to contest it but I want advice if I should or if I should just let it go and do the course. It feels unjust. I did what I deemed safely possible at the time and I slowed down too but I couldn't be expected to slam the brakes on the motorway to not pass under the X. Also, I already started moving out of the lane plus there was no obstruction ever in that closed lane.

EDIT: My dashcam date is wrong, it's definitely recent.

Please see dashcam footage of the incident. I've uploaded it as an unlisted YouTube vide here:

i cant see you have any argument there.
you had plenty of time to get in lane before the highly visible gantry. the fact there was at the time you passed, no obstruction in lane 2 is totally irrelevant.

You passed warning signs at 0:03, 0:28, and 0:40. The flashing red X was visible the entire time.

Imagine that instead of a red X sign, the lane was blocked by a brick wall. Would you driven straight towards it for 45 seconds, then smashed into it at 30mph?
