AC30 : undefined accident offences
Checked 22 July 2026 · How we check our figures
What it means
AC30 is the family's unmarked box: an accident offence recorded where the conviction fits neither of the named codes. On a record it says less than its siblings, so the paperwork behind it is where its facts live, and anyone reading it later, an insurer included, learns only the family and a 4 to 9 range. If this code is on your record, the certificate is the document to keep.
Points and how long it stays
4 to 9 points.
On the licence for 4 years from the date of the offence.
The AC codes are the s. 170 RTA 1988 family: what the law demands after an accident, and the price of skipping it. The duties come in sequence, stop at the scene, give particulars where someone has grounds to ask, and where particulars were not exchanged, report to the police as soon as reasonably practicable and in any case within 24 hours, a ceiling drivers persistently misread as an allowance. Damage alone triggers all of it, injury is not required, and an accident you did not cause still obliges you to stop. The family's signature is its floor: 5 to 10 points on the named codes, the highest starting price of any everyday family, on the 4-year offence clock (gov.uk, checked 2026-07-22). The money mechanics sit in the fine bands guide at /fines/guides/fine-bands.
The usual route
Nothing here is dealt with by penalty notice; the case is charged and heard.
If it goes to court
The certificate of conviction, not the code, tells the court and everyone after it what happened; the fine bands guide covers the ordinary money end.
