A change to speed limits could be introduced nationwide as the National Police Chiefs Council say they indented to review the guidance. It comes after fines for speeding in London have soared in recent years after the Metropolitan Police lowered the ‘enforcement threshold' without an official announcement. However, the Times has now reported that the Met quietly dropped the threshold by 1mph back in May 2019. But the Met says the 259% increase comes because of ‘capacity and is not related to the enforcement threshold change’. In response to the increase, the Met said: “Posted speed limits are the maximum speed that road users should travel at any time ... irrespective of the speed threshold that police commence enforcement action."
