June 24 S172 offence for speeding 79mph on motorway, first offence. Received NIP and completed/returned. Provided driver details. Did not receive offer for workshop/FPN in post. Did not receive reminder either (allegedly sent in July according to police witness statement). December 2024, received SJPN. Want to make police/court aware that had July post been received, would have accepted workshop (to avoid fine, points and increased insurance premium) and would not be in this position. Police advised writing letter as well as completing SJPN. Appreciate need to respond within 21 days in any event but unsure how to proceed/complete SJPN (i.e. guilty/not guilty) and whether to send letter requesting drop charges. Any advice appreciated.
