威尔士的20厘米速度限制使受伤人数减少900人,自实施以来拯救了14人的生命。 Wales' 20mph speed limit reduced injuries by 900 and saved 14 lives since implementation.

在将威尔士公路的默认速度限制降低到20英尺的两年后,数据显示受伤人数显著下降,自改变以来受伤人数减少了882人,根据威尔士政府的数据,总体受伤人数减少了900人。 Two years after lowering the default speed limit to 20mph on Welsh roads, data shows a significant drop in injuries, with 882 fewer people hurt since the change, and 900 fewer injuries overall, according to the Welsh government. 20-30英里公路的伤亡人数下降尤为显著,比速度更快的公路的伤亡人数下降12倍。 The reduction is especially notable on 20-30mph roads, where casualties fell twelve times more than on faster roads. 该政策耗资3 400万英镑,创下了创纪录的请愿书,与1979年开始记录以来3个月中节省的14个生命和最低受伤率挂钩。 The policy, which cost £34m and sparked a record petition, has been linked to 14 lives saved and the lowest injury rate for a three-month period since records began in 1979. 尽管一些批评者仍对安全感到关切,但政府和倡导团体表示,结果很有希望,并提出长期好处,包括降低保险费用。 While some critics remain concerned about safety, the government and advocacy groups say the results are promising and suggest long-term benefits, including lower insurance costs.
