and replacement signs must now display the measurement in both metric and imperial measurements as shown in diagrams 629.2A and 629A. The diagram to 629.1 now consists of two roundels showing length restrictions in both metric and imperial units and both roundels must be placed together. A lifetime saving has been applied to existing signs displaying imperial only units of measurement, and there is no requirement on authorities to replace or remove such signs until such time as they reach the end of their life.
The policy context
6.13
Since 2002, Government policy has shifted towards a general reduction in regulation, and TSRGD is no exception. The removal of the requirements governing the number of terminal signs required should not be taken to mean that such signs are no longer needed. There is still a requirement to place terminal signs, and to place them as close as possible to the point at which the restriction begins or ends. It remains the case that the road user must be notified as to the conditions of any traffic order in place. The placing of such signs either on one side, or both sides of the road is a matter for local judgement on a case by case basis, having regard to factors such as visibility and road layout.

Any reduction in the level of sign provision should be underpinned by robust risk based analysis to ensure any possible safety impacts are considered.
