From the 17th of September 2023, most 30mph limits across Wales will change to 20mph. When you see streetlights, assume that the speed limit is 20mph, unless you see signs that say otherwise.
Most affected streets are in residential or built-up areas where people walk and cycle.
GoSafe, Police and partners will continue to educate and engage with our communities, and enforce 20mph speed limits, to make roads safer for all of us.
