Government bans councils from enforcing 15mph speed limits | The Independent
Last year the City of London Corporation announced that it would be the first local authority to introduce the lower speed limit across the Square Mile in a bid to make its streets safer.
Other councils in built-up areas around the country were expected to follow suit if the change was successful.
But The Independent has learned that the Department for Transport (DfT) has refused to grant permission to the corporation to enforce the planned lower limit.
DfT officials said they were concerned about the accuracy of speedometers at such low speeds and the fact that not all speedometers were marked in 5mph gradations.
