I once helped someone get their car home after one of these was installed. Their license would not be returned until it was installed, but they weren't allowed to leave it on the lot. Someone else drove it there, and then I got to experience the breathalyzer to drive it home.The interesting part is how bad the interlock was. First off, it can apparently randomly not work, so you get three tries. Worse yet, per the official documentation, apparently they can misdetect an ignition while driving at speed, and when that happens you have to pull over and blow within thirty seconds. Now, this is not something you can do while driving, as you have to look at the camera while you do it, on top of needing to have a deep breath. There's no motivation to improve this, because the customer is the legal system, not the person who has to have it installed

I knew somebody with an interlock and if they were around too much car exhaust in a relatively enclosed space, the ethanol in the air would trip the detector apparently.by helterskelter

Having to blow while you're already driving is supposed to be a feature. It's to dissuade people from successfully turning on their car, immediately drinking, and then driving.by wildzzz

30 seconds seems a bit fast to force that though, no? There’s not always a safe place to pull over.by AuryGlenz

If it only kicks in at 45 or lower (i.e., not the highway) then there's always a safe place to pull over. I have no idea how it actually does work though, thankfully.by stronglikedan

Stuck in stop and go traffic on the freeway doesn’t sound like a good place to me, but I’ve never had a DUI so meh?by lazide

Is this comment a joke or do you not understand how dangerous it is to ask a driver to blow into a breathalyzer while operating a vehicle?All this seems to be is a company collecting corporate welfare while doing the bare minimum. Such companies should both be sanctioned and have their leadership investigated for potential fraud.
If you receive public dollars to function, the public should expect some modicum of sensibility and accountability.

The main problem is that, in a lot of parts of the US, your options are "drive or be homeless".The ideal solution is needing less driving overall. But excessively punishing people doesn't fix the problem. They're still gonna drive, most likely.

If they set their own place on fire, they're also homeless. Just as self-inflicted, but significantly less dangerous to third parties than driving drunk.Driving while drunk is not a silly little mistake. A third of all fatal crashes involve drunk drivers. Letting these people drive at all even with a breathalyzer is an abomination. You can expect them to have a similar disregard for other fundamentals of safe driving.

I'm not commenting on the morality of drunk driving. I'm commenting on the effectiveness of just fucking them over, that being, not effective at all.There's this thing in the mainstream where people feel like the best way to handle people doing bad things is to just pummel them into the ground as much as possible.
While that might feel the most justified, that doesn't actually solve the problem. Suspending licenses doesn't stop drunk people from driving, because cars are more or less a necessity.
So, knowing it's a necessity, we have to design the car around that and enforce safe operation by an alcoholic.
Which is a stop-gap solution. A better solution is making cars not a necessity. But until then, we should do the stop-gap.

This is obviously untrue.It wasn't that long ago these devices weren't mandatory and they'd just suspend your license.
I am actually curious now whether that was more effective since the offender had to endure the judgment of the person in their life giving them a ride to work.
by sublinear
3/23/2026 at 10:20:29 PM
I don't understand why this is obviously untrue. Do we have any reason to believe that those people didn't just... continue to drive with a suspended license?Not to mention DUI is a fairly recent development. In the 20th century, it was pretty easy to drive drunk and get away with it.
by array_key_first
3/23/2026 at 11:46:52 PM
Yeah and what's stopping someone from drinking while borrowing someone else's car? Oh they don't want their car wrecked too? They may just drive the drunk to work then.We arrive at the same place with the same real solutions (the people). The technology doesn't do anything except add extra steps and convince the public something was done.
If anything it creates enough hassle for the offender that new crimes are being committed with harsher consequences (domestic abuse), or dragging additional people into crime they didn't intend (negligent entrustment).

3/24/2026 at 12:36:32 AM
> We arrive at the same place with the same real solutions (the people)This is always the case. There will always be murderers, and thieves. But technology just helps.
There are real solutions, and fake ones. Fake solutions include "make people not bad anymore". This just doesn't work, there will always be alcoholics, end of.
If there was less of a reliance on cars, there would be less drunk driving. We take drunk driving as a necessary consequence of transportation, but that's just not true. And, if we had less of a reliance on cars, we could actually suspend licenses sooner.
But as it currently stands, we cannot. We would just be permanently fucking people over in such a severe and unnecessary manner. Being unable to drive is one of the most reliable ways to become homeless in many parts of the US. This will only lead to more crime.

I still disagree.I didn't say it directly, but did mention depending on others multiple times in my replies. If you are truly all alone, that is the biggest contributing factor to becoming homeless. We live in a society.
There often is a ton of help for alcoholics with stuff like this. In fact, I would say alcoholics probably have the most support out of any type of addict because it's so common. When a drunk is forced to seek assistance to make their commute, it often comes with strings attached to put them on the path to quitting. I don't see what's so bad about that.

Someone who drives drunk ought to drive with the interlock for life.Generally driving drunk is a sign of addiction.... And that can come back anytime, and killing bystanders is clearly a worse outcome.

Repeatedly driving drunk absolutely is.You might be a functioning alcoholic, but when alcohol intoxication is so prevalent in your life it interferes with day to day routines activities, it absolutely meets the psychosocial definition of addiction, and likely points to a deeper one.

Every rural area I've ever worked in had a non trivial number of folks who would have 2-3 drinks at the bar/whatever on a Friday or a Saturday and drive home. It was not alcoholism, it was "I'm totally fine to drive, the law doesn't know my limits" etc.On some level that's just the price of wanting to go out and not wanting to drop a bunch of cash on a taxi (assuming you can get one to come).

2-3 drinks on a Friday night isn't.2-3 drinks on a Friday night when you're supposed to drive home is different. I'd also say "I can drink because the law is wrong" is also not exactly a neutral take.

LOL. Do you know how many people are driving with suspended licenses now? The number would skyrocket if systems like these didn't exist.Especially in rural areas, you can get away with driving on a suspended license for a pretty long time before a cop catches you. I know someone who was probably (she wouldn't admit to it) doing it for at least a year.

Especially in rural areasOnce while hot air balloon chasing, we saw a guy driving his 4 wheel drive in the ditches along a gravel road and found out later from someone he had a suspended license.
They said he figured the cops couldn't stop him if he stuck to the ditches and didn't operate on the official roadway.

Unfortunately driving on a suspended is mostly not enforced either, so giving them the carrot of keeping their license is the only thing the judicial branch can do that has much sway (other than jailing them) without being able to order the executive branch to change.by mothballed

Oh wow so the judicial system is developing the software? It's not a private company that only exists to fulfill a government need with zero accountability? What were the terms of their contract? What was their SLA? How do users engage with the company?Sorry but these companies are all scams thrusted upon the public. Any business that takes government money should be held accountable or compelled to engage in workplace democracy.
I'm not a fan of companies making garbage products while getting rich off of public dollars. Just because some people like corporate welfare doesn't mean the vast majority of the public likes it.

3/23/2026 at 3:11:25 PM
Nothing specific yet, but the legal groundwork has been laid both in the US and in the EU. Starting in July, all new cars sold in the EU will need to be able to fit after-market alcohol interlocks. In the US, interlocks are already mandatory for convicted DUIers in most states, but new cars will also have to come with factory installed drunk driving prevention technology in the coming years. We just don't know how far that mandate will go eventually.by sigmoid10

There is no security protocol though. It will be trivial to buy an interlock which always returns 'ok to drive'.by londons_explore

Manufacturers are now encrypting Canbus traffic, voluntarily on current and future models.Buying or selling tools designed to break the law is already illegal - trivial or not. If a driver gets a DUI and possess a NOOP interlock, they are getting an additional charge, and get to help am investigation into the illicit device supply chain.

There is no proposal to require these janky ass aftermarket units, nor require any type of interlock at all.NHTSA was directed to write some guidelines/rules around the implementation of passive impairment detection as OEM features. They have yet to do so, probably because it is flaky technology.
My guess is that the final rule implementation will be similar to the distracted driver detection that is already in many new vehicles.

Meanwhile in much of the USA registration laws aren't enforced. The last time my car was totaled (hit and run) the police didn't even show up for that either so my insurance company just ate the whole cost. DUI laws themselves are largely only enforced to the extent the accused consents to bothering to show up to court.by mothballed
3/23/2026 at 3:09:25 PM
Not really the same. There are proposals to require OEMs to install driver monitoring, but it’s usually IR camera based rather than blow in a tube fuel cell based. These systems are probably going to be a mess but the technology isn’t really comparable to DUI interlock devices and the unreliability of those systems is orthogonal.by bri3d
3/23/2026 at 3:10:50 PM
No, the 2021 infrastructure bill required automakers to install passive technology (passive meaning not requiring any specific actions from the driver) to prevent drunk driving by some future date. However, such technology doesn't really exist yet.by astura

Eh, with lane keeping features I don’t think it’d be hard to at least detect someone swerving a lot. Granted, I don’t think that would detect people that aren’t super drunk, but it’s something.I might be wrong on that assumption - I don’t drink, myself.

I assume you're joking, Either way. One morning when I took the bus to work the bus driver had repeated problems getting the bus to start due to the breathalyser. I heard him complain to the passenger behind him, about it malfunctioning. The passenger volunteered to test this theory, by also blowing into the device. The driver handed him the hose, the passenger gave it a go, the bus started, and the driver shrugged his shoulders, and off we went, only slightly delayed.I'm not sure if this is preventable.
