Regulatory Sign/No Overtaking
|The modern No Overtaking sign|
|TSRGD ref :||632|
No pre-Worboys sign prohibiting overtaking has so far been discovered, and it seems likely that there was no real concern on the matter until the 1960s due to the much lower traffic volumes.
Worboys Report sign
The No Overtaking sign appears to have either been included in the original 1964 Worboys report, or at least a fairly quick addition. It features the head- (or tail-) on silhouettes of two cars, the one on the left in black and on the right in red, depicting danger. Considering that the UK also has double white centre line to convey the same message, the sign does seem a little redundant, but is nevertheless used quite a lot. Often it is used to highlight a recent change to the road, for instance where a new junction and turning lane have been added to a previously straight, clear overtaking opportunity, as on the A82 near Inverness in the picture on the right.
The sign is normally mounted with a plate below detailing the distance of the prohibition, and can also be mounted with an 'End' plate at the further end of the prohibition.
The Irish No Overtaking sign is similar to the UK design, except that both cars are in black, and there is a red diagonal bar across the right hand car. (It is a general rule in the ROI that prohibitory signs include a diagonal bar; similar signs without a red bar indicate limitations rather than prohibitions.)
