Hmm!
13.3 Similarly, the requirement to place at least one repeater sign along a speed limit has been removed. The onus is on the traffic authority to determine the appropriate provision of speed limit repeaters having regard to existing guidance.
In deciding this, it is strongly recommended that consideration is given to the potential for challenge to the enforcement of the speed limit.
13.9 Traffic authorities have a duty to place traffic signs to indicate the effect of a traffic order, including speed limit orders.
Road users should not be placed in the situation where they do not know what restrictions are in place. For speed limits this means erecting signs, prescribed in TSRGD 2016, at the start of a restriction (terminal signs) and for reminding road users of the restriction in place along the length of road to which it applies (repeater signs).
N.B. The bolding is mine...
So, apart from the rules and signs changing by country in the UK (assuming we still are the UK) they will now change by county.
