If u live in Geneva, then a simple way would be to go there and check the speed limit signed!

:-)

I do live in Geneva. There is no signed limit on this road. I think the limit is 80kph as it is out of the city but I am not 100% sure. This is a route taken on the Geneva motorcycle test, hence my question. 

I agree with Sinan, go to see by yourself...  you could have a surprise if you go there at 80kph on your test day....

good luck anyway...

Definitely 80kmh outside of built-up areas.  Any roads that may be part of your test route are worth having some practice rides on so that you have less to think about when the time comes.  A big risk is speed limit signs hidden by trees, but there's also hidden entrances, unexpectedly sharp bends and bad surfaces to check for.  Also look for any points where the road narrows forcing you or the person coming the other way to give way, and make sure you know which of you it should be.  If you have access to an experienced instructor they will know all of these places already.

Also, while I think of it: get as much practice riding in the rain as you can before the test, preferably around the test route.  If you've only ridden in the dry and then it rains on test day you could have a problem.

Just double checked: On minor roads outside built-up areas it is 80 km.

Many thanks for the info. Have my test in a few weeks. Good tip for rain riding Andy, cheers. 

Some of your comments make me seriously weary of meeting you on the roads

I believe that the law doesn't say anything about built on not built areas, it's simply a matter of the road section being within the administrative city limits or not. That road having a name and address is a pretty strong indication of it being within city limits. A quick look on google maps also shows both the city hall and the post office of Troinex being nearby so I very much doubt that it's an 80/area. The limit is most likely 50 and anything above should be indicated with a  sign.

This is exactly my issue with this road and the surrounding areas. If you observe Google street view of this road, there is no signage for speed limits and in my opionion it looks like a rural road, however, there are built up areas very close by. So 50 or 80?

I went riding all around Trionex yesterday and many roads are similar. 

If it is an 80 and I ride at 50 I will fail for not progressing. 

If it is a 50 and I ride at 80 I fail for speeding. 

"Should be..." is a little optimistic.  In most countries, most rural roads don't have marked speed limits so there is normally a general rule that "built up" and "non built-up" areas have a given speed limit (that you are required and assumed to know) in the absence of any other indications.  In The UK it is possible to determine whether or not you are in a built-up area by the distance between the lamp-posts, but I'm not sure what the guideline is in Switzerland so I normally err on the side of caution or just keep pace with the traffic, which is probably what most people do.  Ajay's problem is that he will fail the test if he exceeds the speed limit or if he goes too slow (which is viewed seriously on motorbike tests, because it suggests lack of confidence, which suggests that you'll be dead soon).

I'll try to find the time to go and ride the road in question and see how it looks.  Of course, anyone in possession of one of those completely illegal types of sat-navs that shows speed limits etc. would be able to solve this issue straight away.  But it's illegal, so you absolutely shouldn't use one to check out the route.

Troinex is a commune and essentially residential, so it doesn’t have a “city hall”.

the Swiss choose test routes where speed limits fluctuate.... It may well be the limit goes from 80 to 50 as you enter a village, and even down to 30 if you pass a school... But the changes in limits are normally well sign posted.

the best advice here is to ride the specific route in all weather, and don't rely on google maps or street view as its out of date here by a few years.

good luck with the test and let us know how you get on.

Mairie de Troinex

According to wikipedia:

En localité, la vitesse maximale est de 50 km/h. Selon l'OCR, la limitation de vitesse est valable dans toute la zone bâtie de façon compacte à l’intérieur de la localité, commence au droit du panneau «Vitesse maximale 50, limite générale» et se termine à la hauteur du signal «Fin de la vitesse maximale 50, limite générale». Sur une route secondaire de peu d'importance, ce signal peut être absent ; la limitation prend alors effet dès l'entrée dans la zone bâtie

So it's a mix of checking the signs, and evaluating the compactness of the constructions.

if you have a navigation app (waze, navigator, google maps, sygic...) on your phone, drive through with navigation switched on and be sure to select "show speed limit" in the settings. 

Exactly –

but a “Mairie” isn’t a “City Hall” and Troinex certainly isn’t a city.
