SOBRDRIVE is the first voluntary and private Bluetooth in-vehicle DUI prevention platform. No court order. No stigma. Just a smarter way to make sure the people you love never drive after drinking. Our patented Sober On Start™ (S.O.S.) technology helps prevent a vehicle from starting when alcohol is detected — before a bad decision becomes a tragedy. SOBRDRIVE is completely voluntary, completely private, and installed by choice, not by a judge.

Why We Built SOBRDRIVE


How Sober On Start™ Works
1. Pair. SOBRDRIVE connects over Bluetooth and works with FDA-cleared breathalyzers listed on the NHTSA Conforming Products List — you're never locked into one company's hardware.
2. Test. Before driving, the driver provides a quick breath sample using the SOBRDRIVE app.
3. Drive — or don't. If the sample is clean, the vehicle starts normally. If alcohol is detected, Sober On Start™ helps keep the vehicle from starting until it's safe.
No monthly calibration appointments. No service center visits. Everything is managed from your phone.

Built for Parents of Teen Drivers
Car crashes remain a leading cause of death for teenagers, and alcohol is involved far too often. Teens have grown up surrounded by awareness campaigns — they know the risks. SOBRDRIVE is for the moment awareness isn't enough. Parents install SOBRDRIVE in a teen's first car or a college student's vehicle for real peace of mind: if your child has been drinking, the car helps stop the mistake before it happens. It's not a punishment. It's protection — and one less thing to lie awake worrying about.

Private. Voluntary. Yours.
Traditional court-ordered devices come with violations, lockouts, and reporting requirements. SOBRDRIVE is different by design. You choose to install it. Your information stays yours. There's no court, no compliance officer, and no public record — just a private family decision to put safety first. Safety-minded adults use SOBRDRIVE for themselves too: a built-in checkpoint that helps remove the "I'm probably fine" gamble after a night out.
FAQs
Car breathalyzers, DUI prevention devices, and how SOBRDRIVE works — your questions answered.
How much does a car breathalyzer cost?
The SOBRDRIVE car breathalyzer system costs $129 for the DBS i10 Bluetooth breathalyzer plus $298 for the Sober On Start™ in-vehicle hardware, with service plans starting at just $17.99 a month. There are no service center visits or monthly calibration appointments, making SOBRDRIVE one of the most affordable DUI prevention devices available. One night of ride-shares costs more — and a DUI costs thousands.
Is SOBRDRIVE an ignition interlock?
No. SOBRDRIVE is a voluntary alternative to a court-ordered ignition interlock device. There is no court order, no reporting to a judge, and no tubes mounted in your vehicle. It's a private DUI prevention app and Bluetooth car breathalyzer you choose to install — protection you control entirely from your phone, not a punishment.
Can parents put a breathalyzer in a teen driver's car?
Yes — that's exactly what SOBRDRIVE was built for. Parents install SOBRDRIVE in a teen's first car or a college student's vehicle to help prevent teen drunk driving. Set a BAC limit, schedule automatic testing, and get real peace of mind: if your child has been drinking, the car helps stop the mistake before it happens, and the app offers a safe ride home instead.
What is a DUI prevention device?
A DUI prevention device stops an impaired driver before the drive happens instead of punishing them after. SOBRDRIVE pairs a fuel-cell car breathalyzer with your smartphone and our patented Sober On Start™ hardware: test your BAC before driving, and if you're over your preset limit, the vehicle won't start, while the app helps you call a Hero or get a ride-share home.
How does the SOBRDRIVE car breathalyzer work?
Blow into your paired Bluetooth breathalyzer for a few seconds, and the SOBRDRIVE app shows an accurate BAC reading powered by professional-grade fuel-cell sensor technology — the same sensor class trusted by law enforcement. The i10 also works as a personal breathalyzer anywhere: at dinner, at a game, or any time you want to know before you go.
Do I need to visit a service center for calibration?
No service center visits, ever. Everything is managed from your phone, and the app tracks your test count and lets you know when calibration is recommended (typically after 500–1,000 tests). When it's time, Driven By Safety offers convenient mail-in calibration service to keep your breathalyzer accurate.

DUI Prevention Starting at $17.99 a Month
SOBRDRIVE service is $17.99 per month with no long-term contract. One night of rideshares costs more — and a DUI costs thousands. Protecting your family shouldn't be the expensive option, so we made sure it isn't.
