Metric speed limits – 55 years of dilly-dallying

55 years ago today, the Government announced that,

“Speed limits on Britain’s roads are not to be metricated in 1973, as had been planned by the previous administration, and the Government has no alternative date in mind.”

 
In the 55 years since that announcement, successive governments have failed to set a new date for the changeover to metric speed limits. We reproduce here an extract from UKMA’s main website:

Met Office website drops metric wind speeds

The new version of the Met Office’s weather forecasting website no longer has the option to show wind speeds in metric units. All wind speeds are now in mph-only. Previously, users could choose from a list of different units, including metres per second and km/h.

Government cost estimates to convert all UK speed limit signs to km/h in 1970 were far below £30 million in today’s money

The British Government once developed and examined proposals to change all UK speed limit signs from miles per hour to kilometres per hour in the 1960’s and in 1970. On 9 December 1970, the Minister for Transport Industries John Peyton announced that the proposed metrication of speed limit signs would not go ahead and was postponed indefinitely. The proposed change to metric speed limits was due to be implemented in 1973. Fifty years have now passed since then. Half a century later, UK speed limit signs are still in imperial units. The Department for Transport (DfT) now claims that metricating UK road signs costs too much. However, it would have cost little to convert all UK road signs to metric units according to cost estimates by the Department of the Environment (DoE), which had responsibility for transport at the time, according to historical government documents held at the National Archives.

Opportunity missed to save £ millions on new speed limit signs in Wales

An opportunity to save millions of pounds on new speed limit signs in Wales has been missed by the failure to synchronise the lowering of the default speed limit on roads in built-up areas in Wales with a switch to metric speed limits.

City of London’s 15 mph plan was another missed opportunity to introduce km/h

Between 2019 and 2022, the City of London planned to become the first UK region with a 15-mph speed limit. This plan was blocked by the Department for Transport because speedometers are not accurate enough for low speeds. It meant that it was not technically possible. Like the mass rollout of the 20-mph speed limit, the plan for a 15-mph speed limit across the City of London was another missed opportunity to introduce km/h speed limits.

London speed limits make front page news

Ronnie Cohen, one of our regular contributors, wonders why it  will be easy to find the cash to reduce speed limits in London but has been impossible to convert them to metric.
