Reducing speed limits is the quickest, cheapest and most equitable way of cutting traffic noise. Slower is quieter.
Lower speeds also allow the noise benefits of electric cars to be spread more widely and are foundational for traffic reduction.
20mph limits massively cut toxic diesel emissions. 40,000 die early pa from outdoor fumes – 23 times more than in crashes. 20mph is equivalent to taking over half the petrol cars off the road. Traffic noise also blights lives. 20mph halves perceived noise compared to 30mph. We can’t see pollution, yet it affects our physical and mental health. Demand 20mph today!
