SOBRDRIVE is a voluntary DUI prevention app that helps keep you from driving over your limit β privately, with no court order, no arrest record, and no reporting to anyone. SOBRDRIVE connects to your vehicle via Bluetooth using Sober On Startβ’ (S.O.S.) technology. When a BAC test is scheduled, the vehicle won't start until you pass a breath test. No tube mounted on the dash. No blowing in public. No always-on surveillance. WHY DRIVERS CHOOSE SOBRDRIVE Completely voluntary and completely private β your information is never shared or turned over to any third-party agency. Discreet β testing happens through your phone and a small breathalyzer, not a device bolted to your dashboard. SOBRDRIVE works with FDA-cleared breathalyzers listed on the NHTSA Conforming Products List. REMOTE ACTIVATION Activate BAC testing on a vehicle remotely from the my.sobrdrive.com portal. Turn protection on for the nights that matter without touching the vehicle. ACTIVATION SCHEDULE Set BAC testing times per driver β weekends, game days, every start, or whatever fits. If a scheduled test isn't taken and passed, the vehicle won't start. Deactivation is only possible through the admin portal, and even then, a passing test is still required to start the vehicle. PANIC One tap sends the driver's live location plus audio and video to their chosen contact β more than location-only safety apps provide. FOR FAMILIES AND FLEETS Parents can schedule new-driver testing on weekends. Fleet owners can set testing times and activate vehicles remotely across an entire fleet. Whether it's a barbecue, a wedding, a game day, or a night out β SOBRDRIVE is for anyone who wants to drink responsibly. It helps prevent the first DUI instead of profiting from the last one.
