Request a review of M4 speed limit around Newport
The Issue
In recent years, the speed limit on a section of the M4 motorway around Newport has been reduced to 50 miles per hour (mph) due to concerns about pollution. While we appreciate the efforts to improve air quality, the growing presence of electric vehicles (EVs) on the road presents a compelling reason to reconsider this decision and restore the speed limit to 70mph.
Electric vehicles are rapidly increasing in number and offer a cleaner alternative to traditional gasoline and diesel-powered cars. They produce zero emissions, thereby significantly reducing the overall pollution levels on our roads. According to the Department for Transport's 2023 report, more than 50,000 electric vehicles were registered in the UK in just the past year, highlighting the accelerating shift towards greener transportation.
Furthermore, the reduced speed limit has produced unintended economic consequences. Commuters and transport operators face longer journey times, impacting productivity and increasing operational costs. In a region striving for economic growth, restoring the speed limit would benefit businesses and individuals alike, enhancing the overall effectiveness and efficiency of transportation.
We're calling upon the Welsh Government and relevant local authorities to conduct a thorough review of the current speed restrictions. By considering the latest developments in vehicle technology and balancing environmental goals with economic factors, they can make an informed decision that benefits all stakeholders.
By signing this petition, you are supporting a movement to rethink outdated policies and adapt to our rapidly changing world. Let’s advocate for a speed limit that reflects the needs of today’s society and promotes environmental and economic well-being. Please sign this petition to request a review of the M4 speed limit policy around Newport. Together, we can drive positive change.
