Contravention code 10 is a parking contravention, enforced by civil enforcement officers. If you have received this PCN from Cardiff, Parking Mate AI can check it for defects and prepare a challenge letter for Traffic Penalty Tribunal.

Contravention code 10 means: Parked without clearly displaying two valid pay and display tickets when required. This is a parking contravention issued under the Civil Enforcement of Road Traffic Contraventions (General Provisions) Regulations 2022. Cardiff enforces this via civil enforcement officers on the street.
You have received a penalty charge notice from Cardiff with contravention code 10. In plain English, this means the council considers that you parked without clearly displaying two valid pay and display tickets when required.
The legal basis for this PCN is the parking enforcement scheme, backed by a traffic regulation order (TRO or TMO) that Cardiff must have properly made and signed. Without a valid order and compliant signage, the restriction is not enforceable.
To challenge this PCN, you can make formal representations to Cardiff. If the council rejects your representations, you have the right to appeal to Traffic Penalty Tribunal. The adjudicator's decision is independent and binding on the council.
