Get everything you need to Drive Sober By Choice in one box — and save $128. The SOBRDRIVE Complete Protection Bundle pairs the DBS i10 Bluetooth Breathalyzer with the patented Sober On Start™ in-vehicle module: a $427 value for $298.99. That's the full drunk driving prevention system for about the price of the module alone — the breathalyzer is essentially free.

Here's how it works: the Sober On Start™ module installs discreetly in your vehicle and connects over Bluetooth to the SOBRDRIVE mobile app. Before you drive, take a quick breath test on the i10 — a professional-grade, alcohol-specific fuel-cell breathalyzer. Over the limit you set? Sober On Start™ helps keep the car from starting while the app offers a safe ride home: call a Hero or a ride-share in one tap.

Activate protection remotely from your phone, set automatic testing schedules for weekend nights or a teen's first car, and request a test from anywhere. No court order, no dash-mounted tube, no service center visits — voluntary, private, and yours. The app tracks test counts and offers mail-in calibration when it's time. Requires an active SOBRDRIVE subscription.

The SOBRDRIVE Sober On Start™ module is the patented in-vehicle hardware that turns your car into a drunk driving prevention system — controlled entirely by the SOBRDRIVE mobile app. Installed discreetly in your vehicle, it works over Bluetooth with the app and your paired breathalyzer: take a quick breath test before you drive, and if alcohol is detected over the limit you set, Sober On Start™ helps keep the vehicle from starting while the app offers a safe ride home — call a Hero or a ride-share in one tap.

Everything is voluntary and private. There's no court order, no dash-mounted tube, and no service center visits. Activate protection remotely from your phone, set automatic testing schedules for the moments that matter — weekend nights, a teen's first car, prom season — and request a test from wherever you are. PIN-locked settings keep your rules in place.

Sober On Start™ works with FDA-cleared Bluetooth breathalyzers listed on the NHTSA Conforming Products List, including the DBS i10, so you're never locked into one company's hardware. Requires the SOBRDRIVE app and an active subscription. Drive Sober By Choice.

The DBS i10 Bluetooth Breathalyzer is an alcohol-specific, fuel-cell breathalyzer that connects wirelessly to Apple iOS and Android smartphones — the handheld heart of the SOBRDRIVE voluntary DUI prevention platform. Unlike cheap semiconductor breathalyzers, the i10 uses professional-grade fuel-cell sensor technology trusted by law enforcement and treatment professionals, so it responds only to alcohol and delivers an accurate BAC reading in seconds.

Pair the i10 with the SOBRDRIVE app and Sober On Start™ vehicle hardware to test before you drive. If you're over the limit you set, SOBRDRIVE helps keep the vehicle from starting and offers safe alternatives — call a Hero, get a ride-share, and get home safe. No court order, no service center visits. Voluntary, private, and controlled from your phone.

Compact enough for a pocket, purse, or glovebox, the i10 also serves as a personal breathalyzer to check your BAC anywhere. The app tracks your test count and alerts you when calibration is recommended (typically after 500–1,000 tests), with mail-in calibration service from Driven By Safety. Requires an active SOBRDRIVE subscription.
