We Stopped Trusting ‘I Only Had Two’ And Started Using THIS to Get an Accurate Blood Alcohol Number

September 14, 2026|By Jess M.7 min read

It was supposed to be a normal night out. Dinner, a few bottles of wine, catching up with friends. You know the drill.

We polished off our 3rd bottle and some shared desserts, and decided to head home. There were a couple of cars parked outside, and we just had to figure out who was going to drive everyone home.

It was a routine we’d followed countless times before.

Until one night, we got pulled over just a few blocks from the restaurant.

It started with a broken tail light, but quickly escalated to the cop making Diane, that night’s designated driver, do a field sobriety test and then a breathalyzer… And she blew a 0.07!

That’s as high as you can go before they take you away in the back of the cop car, and for a split second we all thought that was what was coming next.

“You’re blowing a 0.07%. That is a hair away from jail time. If you had stumbled once on that line, you’d be in handcuffs right now.”

By this point our Diane was absolutely balling her eyes out. She had a great job, kids that depend on her to get everywhere, and in a split second it was all at risk.

Luckily, the cop took pity on us that night, let Diane off with a warning, and made us all leave the car exactly where it was and get an Uber home.

That might have been one of the quietest drives home ever, everyone was pretty shaken.

Nobody wanted to be the friend who asked the designated driver, “Are you sure?”

But that night made one thing painfully obvious: none of us were very good at judging our own blood alcohol level.

We Weren’t Reckless. We Just Never Had A Way To Know For Sure.

Before that night, we had our own little system for deciding who should drive.

Counting drinks seemed like the obvious answer. Whoever had the fewest should drive.

But drinks aren’t all the same, and neither are people. A “couple of drinks” could affect two people very differently.

Going by gut feeling was our next option. If someone said, “I feel fine,” we usually took them at their word. But feeling fine doesn’t tell you what’s actually in your bloodstream.

Picking whoever seemed the most sober was even more subjective. We’d look at who was talking normally, walking straight and acting like themselves.

But none of those options gave us an actual number.

We weren’t ignoring the dangers of driving. We were trying to be smart about it. The problem was, we had no objective way to settle the question.

You don’t want to accuse your friend of being drunk. You don’t want to make things awkward. And you definitely don’t want to tell someone they’re “not allowed” to drive.

So we’d usually just trust them.

But after that close call, we decided we were done guessing.

The Ten-Second Rule That Changed How We Drink Together

After that close call, we knew we needed a better way to decide who should drive.

That’s when my friend Brandy, the big sister of the group, mentioned a keychain breathalyzer she’d heard about.

We all ordered one that weekend. It was small enough to keep with our keys, but it gave us something we’d never had before: an actual BAC number instead of a guess.

After that, going out was simple.

We all tested ourselves, and the numbers told us who was safe to drive. And we all agreed that there were no exceptions, and no hurt feelings.

It wasn’t about trust. It was about having an actual answer instead of a guess.

It’s fast, discreet, and super simple. All you have to do is breathe into it, wait a few seconds, and a number shows up right on the screen.

You don’t even have to use the app if you don’t want to. Although we usually pull it up on our phones too, just to see the full readout.

It became part of the routine. Dinner, drinks, catching up…

Then BACtrack.

We’ve been using it for months now. Nobody’s ever been offended by it. If anything, it made everyone feel safer.

The Same Technology Police Use Fits on Your Keychain

Here’s the part that made us actually trust it: the C6 uses BACtrack’s BluFire fuel cell sensor. That’s the same technology used in professional and police-grade breathalyzers.

It’s not a gag gift or some cheap knockoff. The BACtrack C6 gives you numbers you can actually rely on.

And that matters, because feeling sober and being sober aren’t the same thing. We found that out the hard way!

The fact of the matter is, someone can be talking normally and walking in a straight line. AND they can still be well over the legal limit.

We all agreed that nobody in our group drives unless the number says they’re clear.

No More Debating Who’s Fine To Drive. Just Press the Button & Blow

The BACtrack C6 works in whichever mode fits the moment.

Standalone Mode gives you a number right on the device. After you blow into the device, a bright OLED screen lights up with your BAC number, no phone needed.

You can also use it in App Mode, where it pairs with your phone over Bluetooth. In App Mode, the reading shows up on your phone screen instead, along with a few extra features.

Either way, it’s simple to use with just one button.

That’s all there is to it.

If you’re using it in App Mode, it also runs ZeroLine. That gives you an estimate of how long until you’re actually back to 0.00%.

More than once, that number talked someone out of “I’ll just wait it out in the car.”

Local News Put BACtrack C6 Against A Police Breathalyzer. Here’s What Happened.

At some point, one of my friends wondered aloud, how do we know this thing is actually accurate?

Turns out, we weren’t the only ones who had that question.

Fox 2 Detroit teamed up with the Allen Park Police Department to test the BACtrack C6. They had 5 volunteers drink a few drinks, then blew into the BACtrack C6 and the department’s own police-issued breathalyzer, side by side.

The results were surprising. The C6 matched the police breathalyzer every step of the way!

So if you’re wondering whether this portable breathalyzer is accurate, it is.

And my friend and I aren’t the only ones who think so…

487 Reviews Later, Friend Groups Just Like Mine Are Doing The Same Thing

If you check out BACtrack’s website, you’ll find hundreds of reviews from people who’ve made the C6 part of their routine.

Countless groups, from college friends to family gatherings to weekend boat trips, have started using the same simple check before anyone gets behind the wheel.

Less Than The Price Of A Bar Tab. Worth A Lot More.

Here’s the thing about that night we got pulled over…

A DUI can cost you thousands in fines, a suspended license, a lawyer, and higher insurance for years. Not to mention what could’ve happened if we’d gotten in an accident instead of being pulled over.

Two C6 breathalyzers cost $99. One alone runs $69.99.

That’s less than what most of us spend on the dinner that started this whole thing.

We bought a whole bunch so nobody in the group ever has an excuse not to check. We all have our own. And some of us even got extras for the car or the liquor cabinet at home.

BACtrack covers the C6 with a 1-year warranty and a 30-day money-back guarantee.

So if it’s not part of your routine within a month, you get your money back. No pressure, no risk.
