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.

Why do highway authorities take so long to replace worn-out signs?
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.

Following on from the previous MV article about the 100 ml liquid rule, we look at other airport regulations that involve measurements. Where measurements are involved, they tend to be expressed in the metric system, which is used worldwide. Metric units are used in airport regulations around the world. Here, we focus on rules at British airports.

On 4 April 2023, London City Airport scrapped the 100 ml liquid rule. 1 Since 2006, airports worldwide have insisted that travellers can only bring liquids in containers of up to 100 ml in their carry-on bag. 2 These days, we take it for granted that the 100 ml limit for liquids at international airports around the world is exactly the same quantity. This is a triumph for the metric system, which replaced many different national systems long ago. Before the metric system, the same unit names were used for different quantities in different national measurement systems and there was no common definition for these units. The worldwide 100 ml liquid rule shows the benefits of a world standard measurement system for international travellers (i.e., the metric system).

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.

The London Assembly Transport Committee recently held a Road User Charging public consultation between 9 February 2023 and 10 March 2023. Under these plans, drivers in London could be charged for every mile they drive. This anti-pollution measure is mile-based whereas emissions levels are kilometre-based.

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.
