20mph Speed Limits

Following the announcement by the Welsh Government on Tuesday 23rd April 2024 outlining their plans for 20mph speed limits, we are accepting suggestions on which roads you believe should be exempted from the 20mph national speed limit in Wales.

Please complete the survey below or email us (20mphspeedlimits@carmarthenshire.gov.uk) your suggestions (along with valid reasons) for why a road should be exempted from the 20mph national speed limit in Wales, we will log your feedback and review it once new exceptions guidance is available from the Welsh Government. We expect to receive this guidance by the summer. In the meantime, we would also be grateful to receive your postal address to assist us in the review process.

We won’t be able to log any general comments about the 20mph National Policy, as that is a matter for the Welsh Government and Welsh Government Ministers. You can contact the Welsh Government​

If your feedback relates to a Trunk Road, these are not the responsibility of Local Authorities, so please email TrunkRoads20mph@gov.wales.

More information on Trunk Roads is available on Datamap Wales.

If you support 20mph on a road where you live, we'd also like to hear from you. Email: 20mphspeedlimits@carmarthenshire.gov.uk

We will be accepting suggestions until the end of August.

Reporting Speeding Concerns

The role of enforcing the existing speed limit rests with the Police and GoSafe rather than the County Council as we have no enforcement powers in this respect. You can submit a community speeding concern directly with GoSafe, and they will investigate.
