I am in the same position, caught speeding but hadn't updated the V5 and the previous owner was abroad until last month. I now need to respond to the NIP, but the original date of the offence was 28/05/23 and so I will leave it until December to reply.
Which option would be the most suitable to reply with to allow it to time out?? 1a Speed Awareness / 1b Fix Penalty / 1c Court Date?
