Ah OK. I have tried Waze but found it kept notifying me of absolutely everything (not just “police” but also long-vanished accidents or queues of traffic, cats in the road, low hanging trees, flocks of penguins etc.) so I went back to Google Maps.
Maybe I should try it again and have a poke around in its settings.
Sounds like rotten luck. I’ve only ever had one speeding offence in 30 years on the road, and that was doing 94km/h in a 90km/h on the peripherique around Paris. Ironically I was the slowest vehicle being overtaken by everybody else, and was so focused on all the motorbikes coming up either side in four lanes of traffic, that I wasn’t focused on my speedometer. On the fine, it said the tolerance of the speed camera was 91km/h. So much for a 10% tolerance!
If you go into settings - alerts and reports, you can choose what gets flagged up.
From what I’ve read, receiving an indication of a camera is permissible, which is what Waze and Tomtom do; operating equipment that detects radar is not.
So Tomtom indicate “danger zones”; I assume Waze does the same thing, though - despite the best efforts of SFers - I’ve never been able to get Waze to work.
Auntie Google explains -
Under Article R. 413-15 of the French Highway Code, it is strictly forbidden to use or possess devices that detect or warn of precise camera locations. Drivers face fines of up to €1,500 and risk having their vehicle confiscated.
To comply with the law, navigation apps like TomTom AmiGo and Waze operate by replacing exact camera pings with broader “Danger Zones” or general hazard alerts. These zones cover a wider stretch of road (often 4km to 20km) where speed checks or other risks might occur, making the technology legal to use.
We use OSM and it tells us that a speed cam is coming up. Waze sounds good but the Israeli connection and that Google now owns it makes it a no from us.
I just had my fine from our UK trip, somewhere between Abbeville and Rouen. Grrr, only a few km so not the end of the world, 45€. I am pretty bad at sticking though, don’t mean to and we have an Alpha 159 and you can’t feel it, and it doesn’t have cruise control. My feet do 100km/ hr as that is what Aussie speed limits are 
.
Thank you, I have poked Waze on my phone with a sharp stick.
There are a heck of a lot of options to turn off!
I find it interesting the way speed limits have been changing has broken the moral link between speeding and being caught. Now it’s just a hazard of driving rather than bad behaviour.
Like potholes, or somebody turning left without signaling?
I think there is a big difference between speeding like the crazy young things do, in a dangerous, aggressive, way over manner and the type if speeding we are talking about, a few kms over. Not even that long ago being a bit over +/-10% wouldn’t have got you in any trouble, and rightly so imho. To safely overtake for example one needs to be allowed to accelerate! In the deep country, through the woods here I tend to drive per conditions, this may mean me doing 50 or 60 in an 80 zone if needed ,(although I get hugely frustrated when people do that when totally unjustified, but on roads with nobsafe overtaking, it is dangerous IMO. Wait until the rest of us have got to work 
then drive at 60!!).
It’s 5 km/h marge de tolerance up to 100 km/h then 5%. A penalty notice will show the speed with the tolerance deducted leading to some people saying they ‘got done’ for 91 in a 90 when, in fact, they were doing 96..
In the UK enforcement starts at 10%+2
I’ve seen it claimed that the French police/gendarmes cannot inspect a sat nav or phone without a court order.
Logically, if they stop you you’ve already been pinged so there would be no need to inspect devices. And, if it’s ticket in the post there is no such inspection possible.
I was correctly fined €44 for 86 in an 80 a few years ago, so 1kph beyond the 5kph “tolerance”.
No speed awareness course required or points being deducted.
Driving on the RDs is usually drama free for me in SE 47.
It’s the unnamed Routes Communales where folks drive like they’re on a rally stage despite the roads being one tractor wide and very often full of tractors that I have 95% of my Brown Alerts.
This is widely misunderstood.
There is a standing recommendation that forces use 10% plus 2mph but it is just that - a recommendation, and not all areas implement it.
There’s a hierarchy too. Ever noticed how no overtaking lines are more-or-less sacrosanct whereas the same driver will happily break the speed limit. And tailgate too obviously.
Stop signs also pretty much sancrosanct.
Some things are obvious for safety, but speed is not.
That’s how it seems sometimes.
I’m much more concerned about people speeding in places where it’s not safe to do so than I am about someone doing 110kph on a long straight road in the country with a 90kph limit.
