Ooono Co Driver 2 Traffic Safety Device
I was sent one of these Ooono Co Driver 2 ‘Traffic Safety Devices’ to try out. As this is a relatively new piece of kit available to motorists, I’d better explain a bit of background and what it sets out to do.
Ooono is a Danish company, and its Co-Driver device dates from 2017. They specialise in developing technology-driven solutions aimed at enhancing everyday safety.
The Ooono Co-Driver 2 is a smart traffic safety device designed to help you stay alert and informed while driving. It provides timely audio and visual warnings about upcoming road hazards and speed cameras, aiming to help you stay aware of your surroundings and avoid unnecessary fines or dangerous situations. With millions of users in its community, the device receives real-time updates, helping to ensure that alerts are accurate and up to date.
Unlike traditional navigation tools, the Co-Driver 2 has no screen, reducing distractions and keeping your focus on the road. It’s designed to be simple and intuitive with a single button and no need to interact with your phone. The device features a rechargeable battery – lasts up to a month before needing recharging – and comes with a USB-C cable for convenient in-car charging. It’s also compatible with Apple CarPlay and Android Auto, seamlessly integrating with your car’s infotainment system to provide safety alerts and navigation support without requiring you to take your eyes off the road.
After a week of using the Co-Driver 2 for all of my car journeys, I would say that it’s a very subtle and smart looking piece of kit. It won’t look out of place in any modern car – and in fact will add a real technological boost to most vehicles.
Where it’s not quite so strong, is in the accuracy of the various alerts. It gives a nice ‘tring-y’ sound when it thinks you’re going over the speed limit (My BMW already does this, although the BMW’s version is much less noticeable). The Ooono one is much clearer to hear.
But, with both the BMW and Ooono relying upon what I think is a combination of Geo Location and pre-set mapping, they don’t get it right all of the time. The Co Driver 2 warned me that I was going over 30mph on a dual carriageway that had a fixed speed limit of 50mph (not a variable speed limit). So, what this means is that the speed alert from the Ooono is helpful, but you can’t rely on it totally. You still need to be aware of the ‘real’ limit on the road you’re on. My BMW also regularly gives false positives, getting the speed limit wrong – even on major roads and motorways.
I found the same with fixed speed cameras. It sounded like an air raid warning when I approached one. There’s no way you could miss the alert, but then later that day I sailed past a few similar, fixed speed cameras – that have been there for years – and it stayed silent.
So, would I recommend this? I would say yes, if you don’t have the feature built-in to your vehicle subtly warning you when you go over speed limits or approach speed cameras. As I’m used to getting these alerts from my BMW, I’m automatically programmed to come off the accelerator when it sounds (and this isn’t a bad thing).
But, you still need to have your wits about you and know what’s going on around you. We could certainly do with bringing up the general standard of driving on the roads, and the Co Driver 2 is definitely progression towards this. Hopefully the mapping and Geo Location will also get better with time!

Known issues and safety
Recall check: we searched GOV.UK product safety alerts, reports and recalls (Office for Product Safety and Standards) for “OOONO” on 18 October 2026. No notice was found [3].
Accuracy: alerts depend on community and map data, so they may be wrong or missing. OOONO’s page says a warning can be reported as outdated using the button on the top [1]. You remain responsible for the speed limit you are driving at.
Legality: RAC says there are no laws banning speed camera detectors in the UK, but that jammers that block the signal from police speed cameras are against the law [2]. RAC does not mention this device. Check the current rules yourself.
Questions people ask
Does it need a subscription?
OOONO says no. All the CO-DRIVER NO1 and NO2 features are free after purchase, including the app and the CarPlay and Android Auto integration [1].
How often do I charge it?
About once a month, according to OOONO. It flashes red and sounds when it needs charging, and charges in the car by USB-C [1].
Does it work with CarPlay and Android Auto?
Yes. Connect through Bluetooth or USB-C and enter your destination in the navigation [1]. Without CarPlay or Android Auto you can use the OOONO app instead [1].
Is it legal in the UK?
RAC says there are no laws banning speed camera detectors in the UK, while jammers are illegal [2]. This is not legal advice.
Where does the data come from?
OOONO says it comes from its driver community in real time, plus external data partners [1].
Alternatives
- Phone navigation apps with camera alerts: They need your phone screen or audio. OOONO’s own page makes this comparison, so treat it as marketing [1].
- Other speed camera warning devices: Compare whether they need a subscription, a screen or a phone connection.
