TfL hails ‘huge impact’ of 20mph limits


New data shows there has been a ‘significant reduction’ in the number of collisions since the implementation of 20mph speed limits on key roads in London. In March 2020, TfL introduced a 20mph speed limit on all of its roads in central London.

Monitoring of the schemes show that since they were introduced, the number of collisions has reduced by 25% (from 406 to 304), and collisions resulting in death or serious injury have reduced by 25% (from 94 to 71). Meanwhile, collisions involving vulnerable road users are down by 36% (from 453 to 290), as are collisions involving people walking, by 63% (from 124 to 46). TfL says the figures demonstrate the ‘huge impact’ of lowering speeds across London.

Penny Rees, TfL head of healthy streets investment, said: “It’s brilliant to see the huge impact the introduction of 20mph speed limits has had on road safety around London.  We are determined to eliminate deaths and serious injuries from London’s roads in line with our Vision Zero goal, and this data proves that lowering speeds is crucial to achieving this goal.  “20mph speed limits not only save lives, but also encourage Londoners to travel in more active and sustainable ways.”
