I will set the scene:
I am going back home on 14/03/25 near empty roads, clear and dry weather on the A3 at 1AM
I was driving and began being trailed by an unmarked unit, this unit trailed me for 2 miles.
I was speeding on the dual carriage way at around 70mph ish which at some point got to 90.
There was construction at some point and a bus which slowed me down and waited to get past, thus I consequently slowed down. Eventually a marked unit was waiting for me which flashed me and pulled me over.
I stated I did not know why I was stopped and when asked how fast was I going I said I believe the speed limit.
He mentioned I went past 3 speeding cameras and slowed down.
They breathalysed me which got 0.00
They mentioned to me due to me "overtaking" and "swerving" ( I did not swerve I have a dashcam) and my speed he is reporting me for Dangerous driving, he mentioned I will get a letter soon and I can choose to accept it or challenge it.
He then cautioned me and I asked if I was being arrested to which he said "No no, you can drive off home and continue to drive"
I held my license for just over 1 year, had a clean license no past criminal history.
What is my scenario looking like, I would appreciate honest advice.
I do have dashcam footage if someone would care to review it (it does not have my speed on it, only time)
