not legally binding ?

I am not quite happy with this "not legally binding", wikipedia says "recommended by a governing body, but is not enforced .... While travelling above the advisory speed limit is not an offence, liability for any collisions that occur as a result of traveling above the limit can be placed partially or entirely on the person exceeding the advisory speed limit". (typos verbatim from WP;)

So I would suggest to remove the "not legally binding" from the lead sentence and insert a verbose precise description somewhere in the body. Also the precise details might be country dependent? RicoZ (talk) 14:33, 13 December 2015 (UTC)

In Ontario, Canada, these speed limits are indicated by a yellow sign and are found on every highway onramp and offramp, many curves, and some other places like hills. They are only suggested speeds, they are not legally binding. It is common to find both a binding speed limit sign (e.g. max 50) and an advisory speed sign (e.g. max 40) beside each other on curves.

The "not legally binding" bit is a recipe for trouble, it would completely suffice to say "advisory speed limit". Drivers should know what it means in their country. RicoZ (talk) 21:43, 13 December 2015 (UTC)

Use on intersection nodes?

On roads with an advisory speed through an intersection, is it acceptable to put the maxspeed:advisory=* tag on the node of the intersection itself, or is it necessary to cut out a short section of the road through the intersection and put the tag on that?

-- Roadsguy (talk)

@Roadsguy: Tagging it on the intersection node would be ambiguous, because typically the advisory speed limit only applies when traveling on the main road, not the cross street. Better to cut a short section from the warning sign going in one direction to the warning sign going in the opposite direction. – Minh Nguyễn 💬 07:52, 22 November 2021 (UTC)

maxspeed:forward/backward:advisory

Using "maxspeed:forward:advisory" and "maxspeed:backward:advisory" for recent edits. Relatively self-explanatory, for cases where opposing directions have different advised speeds. -- Nocturnalmusings 06:50 UTC 2021 November 22

@Nocturnalmusings: maxspeed:advisory:forward=* and maxspeed:advisory:backward=* are well-used, with hundreds of occurrences. The general-purpose forward/backward suffixes tend to occur after subkeys that are specific to a particular top-level key. I've added a mention to the article. – Minh Nguyễn 💬 07:50, 22 November 2021 (UTC)
Much appreciated. Will update aforementioned edits. -- Nocturnalmusings 09:09 UTC 2021 November 22
