No overtaking signage: Metrication and other suggestions

In this article I share my thoughts on "No overtaking signage".  Not much needs to be done, except for metrication, making the supplementary plates more symbolic, and given the sign means no overtaking already, then perhaps remove the supplementary plate "No overtaking" (and thus eliminate the need to translate for bilingual signs too).

In addition a new sign "No overtaking for lorries" can be considered.  This could be used for example, on some sections of 2 lane dual carriageways or motorways where "elephant racing" (lorries attempting to overtake other lorries) is a problem and is slowing down traffic significantly (an example is part of the M3), but I wouldn't advocate "No overtaking for lorries" being used everywhere - only when absolutely necessary and where there is a safety benefit and improved traffic flow. I would not recommend using "No overtaking for lorries" as a blanket replacement for crawler lane signage.

As with the previous articles on road signs, example images are shown in this article:

No overtaking signs

No overtaking sign. No change is required if there was no supplementary plate.
Any supplementary plate saying "No overtaking" can be removed.

No overtaking 500 m ahead (after metrication).

Wholly symbolic way of saying "No overtaking for 1500 m", after metrication.

No overtaking allowed between 09:00 and 18:00.

No overtaking for lorries (possible new sign)

Lorries not allowed to overtake.

Lorries not allowed to overtake between 09:00 and 18:00. Note that a more realistic scenario is for the restrictions to apply at peak hours instead (e.g. 07:00 - 09:00 and 17:00 - 19:00)

No overtaking with exemptions or for specific vehicles

No overtaking allowed, unless overtaking a tractor.

No overtaking allowed by buses, lorries, or cars with trailers between 09:00 and 18:00.

End of no overtaking restrictions (if these signs do not already exist)

End of overtaking restrictions.

End of overtaking restrictions for lorries.
