The total estimated cost for implementing the speed limit change from 30 mph to 20 mph, including the cost for changing signs and markings on roads, has been published in the Regulatory Impact Assessment (RIA) undertaken by the Welsh Government on 20 mph speed limits. The published document gives a breakdown of road sign costs. These costs are several times lower than the Department for Transport (DfT) cost estimates of conversion of road traffic signs to metric units in cash terms despite 50% inflation during the 16-year period between the two reports.

Cost is no barrier to rollout of 20 mph speed limit
For years, the DfT has given cost and diversion of funds from other parts of the transport budget as arguments against the metrication of UK road signs. While all kinds of arguments have been made for and against the reduction of the speed limit on local roads to 20 mph in London and Wales, I have not heard any opponents of the rollout of 20 mph speed limits say that it costs too much or that it diverts funds from other parts of the transport budget. This shows that the DfT arguments against changing road signs to metric units are bogus.

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.

The other victory UKMA won in the end
The previous article describes how weights and measures legislation was saved from the axe by changes to the REUL Bill. There was another important victory that has also been won by UKMA with the help of powerful stakeholders though it took years to win. UKMA spent years fighting the Department for Transport before the battle to make metres mandatory on restriction signs was eventually won.

There are some worn-out signs that have been in place for months, possibly years, but await replacement. On 4 May 2023, I contacted my local council to ask them to replace a worn-out height sign with a new one. It has been worn out for at least two years but has still not been replaced. I know that it has been worn out for this long because I still have a picture of this worn-out sign that I took on 26 May 2021. Despite informing the local council highway authority that it needs replacement, it has still not been replaced.

Odometers in vehicles measure distances travelled in tenths of a kilometre or tenths of a mile, depending on the unit used in the target market. A tenth of a mile is 176 yards. However, there is nothing on British roads that is measured by tenths of a mile.

According to the US Central Intelligence Agency (CIA) factbook, “only three countries – Burma (former name for Myanmar), Liberia, and the US – have not adopted the International System of Units (SI, or metric system) as their official system of weights and measures”. 1 The key word in this sentence is “official”. It does not mean that they do not use the metric system. In fact, Myanmar and Liberia use metric speed limits unlike the UK.

On 4 April 2023, YouGov carried out a survey of 4808 British adults about changing the rules around speed and distance in the UK from miles to kilometres. It revealed insights on different attributes based on region, politics, and age.

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.

Some aspects of measurement usage in the British transport sector appear to be uniquely British with no known parallel across the whole world. The British really are out of step with the modern world when it comes to transport measurements. The British transport sector is one of the last imperial bastions in the UK thanks to DfT policies.
