Cardiff Speed Limits & Enforcement Guide
Cardiff, Wales drivers and residents need clear guidance on how speed limits are set, enforced and reviewed locally. This guide explains how local Traffic Regulation Orders (TROs) and enforcement responsibilities operate in Cardiff, who to contact to report concerns, and the practical steps for asking for limit changes or appealing penalties. It summarises enforcement roles, typical outcomes and administrative processes used by Cardiff Council and partner agencies, and points you to the official council and policing resources for applications, complaints and procedural details.
How local speed limits are made
Local speed limits in Cardiff are created and amended through Traffic Regulation Orders (TROs) and related local traffic measures administered by Cardiff Council. The council follows statutory processes when consulting the public and publishing proposals before making an order. Delivery may reference Welsh Government guidance and national traffic legislation where appropriate.
Penalties & Enforcement
Responsibility for enforcing speed limits in Cardiff is shared: the police enforce criminal speed offences and may issue summonses, fixed penalty notices or prosecute; Cardiff Council manages civil traffic controls such as parking and certain moving-traffic restrictions where Civil Enforcement Officers may issue Penalty Charge Notices. Safety camera partnerships and roads policing units support speed enforcement on trunk and local roads.
- Fines for speeding: not specified on the council pages listed below; criminal penalties and fixed penalties are handled by police or courts.
- Civil penalties (parking, moving traffic): amounts and charge bands are published by Cardiff Council on specific penalty notices; check council resources for current figures.
- Escalation: first, repeat and continuing offences are processed under police or council procedures; specific escalation ranges are not specified on the cited council pages.
- Non-monetary sanctions: may include penalty points, court summons, orders, vehicle seizure or disqualification where criminal procedures apply.
- Enforcers and contacts: enforcement is undertaken by South Wales Police (roads policing and safety cameras) and Cardiff Council Civil Enforcement team; see Help and Support / Resources below for official contacts.
- Inspection, complaints and reporting: report dangerous speeding or request local reviews through the council reporting pages or via police non-emergency roads policing contacts.
- Appeal and review routes: appeals against council civil penalty notices follow the council’s published appeal route; criminal matters follow court processes — exact time limits for appeals are set in the issuing documentation or legislation and are not specified on the cited council pages.
Common violations and typical outcomes
- Exceeding signed speed limit - police enforcement, fixed penalty or court action depending on severity.

Applications & Forms
Applications for new or changed speed limits, or requests for traffic calming, are normally submitted to Cardiff Council as TRO proposals or as part of the council’s highways request process. Fees, forms and supporting documentation for TROs or traffic management requests are published on the council website; if no dedicated online form is available the council accepts written submissions and formal requests via its highways team. Specific form names or numbers are not specified on the council summary pages referenced below.
