Eight years after the Traffic Signs Regulations and General Directions (TSRGD) were updated to require all new vehicle restriction signs to show vehicle width and height restrictions in both metric and imperial units, the Department for Transport’s Traffic Signs Manual (TSM) has still not been fully updated to take account of the fact that new imperial-only vehicle restriction signs are no longer authorised.

British driver caught speeding in France after misreading km/h for mph
A British driver in France has been stripped of his driver licence after misreading a 125 km/h speed limit sign for 125 mph. This is not the first time that miles and kilometres have been confused when reading speed limits. Back in January 2021, Metric Views reported a similar case of a high-profile foreign Premier League footballer who confused km/h and mph when driving in the UK. And it is unlikely to be the last time it happens.

1 July 2024 marks the 50th anniversary of the switch to metric road signs in Australia.
For about a year before the change, car manufacturers fitted dual speedometers to their vehicles and, after 1974 all new cars were fitted with metric-only speedometers. Several kinds of speedometer conversion kits were available. As a result of all these changes, conversion on the roads occurred without incident.

Do our motorway junction numbers hinder the use of driver location signs?
Recent Metric Views articles have discussed the poor awareness of the meaning of driver location signs amongst the general public, and argued that despite their inclusion in recent editions of the Highway Code, there is still a need for a new public information campaign about these signs.
However, could there be another reason why driver location signs are poorly understood? And is there a solution that would both increase public awareness and increase their use?

Government once admitted that road signs cannot remain imperial in a metric world
Official government documents from the early 1970’s stated that road signs cannot remain imperial while the rest of the UK goes metric. One of these documents is an official letter from the Ministry of Transport (MOT), as the Department for Transport (DfT) was then called. Would you believe it? Compare that with the current attitude of the DfT today, which directly contradicts the admission in the MOT letter.

On 9 December 1970, the Minister for Transport Industries John Peyton announced that the Government have decided that speed limits will not be made metric in 1973 and have no alternative date in mind. Why did the Government scrap the metrication of speed limits? Historical government documents give various reasons for scrapping the planned conversion. This article will show some of these documents, which reveal the reasons the Government gave for its decision.

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.

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.

I came back from a short trip to Gibraltar one week ago and noticed that all their road signs were metric. The only imperial units I saw on road signs there were on dual-unit restriction signs. Many showed metres only, but none showed only feet and inches. Gibraltar road signs are almost exclusively metric with only limited use of imperial units, the mirror image of the UK situation.

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.
