Isle of Anglesey County Council consulted with the public on proposals for changing certain roads that are currently 20mph back to 30mph. This consultation took place between 23 May and 13 June 2025.
The proposals were submitted to the Planning and Orders Committee for their approval. The proposals were discussed at the latest meeting which took place on 1 October 2025.
There were 25 exception proposals. The Planning and Orders Committee has approved 22 of them.
Isle of Anglesey County Council will proceed to confirm the traffic regulation orders (TRO). The council will arrange for a contractor to change signs and road markings as soon as the order is operational.

The following exception proposals have not been approved by the committee and will therefore be withdrawn from the traffic regulation order.
These roads were proposed to change from 20mph to 30mph. Isle of Anglesey County Council's Planning and Orders Committee decided to not pass the proposals.
These roads will remain as 20mph speed limits.
Safer communities
Isle of Anglesey County Council had previously introduced advisory 20mph speed limits outside schools due to the recognised health and safety benefits.
A Welsh public health study estimated that the 20mph default speed limit could result in:
- 40% fewer collisions
- saving 6 to 10 lives every year
- avoiding 1200 to 2000 people being injured every year
Evidence shows that people feel more comfortable to walk and cycle when vehicle speeds are slower, and it is safer for children to walk to school; and older people, disabled people or people with additional needs are also more able to travel independently.
