SOBRDRIVE is voluntary DUI prevention for people who want to make sure they never drive impaired. Pair with your SOBRDRIVE module by Bluetooth, take a quick BAC test, and start your vehicle knowing you're under your own limit. No court, no monitoring agency, no reporting. Just you and your decision to get home safe. PANIC 2.0 When something goes wrong, one tap or a shake of your phone sends help. Your Heroes (up to five trusted contacts) get a text the instant you trigger it, with a live map link that keeps updating until you end the alert. They can tell you they've seen it, that they're on the way, or that they've called 911, and you see their responses on your screen. The alert can only be ended with your PIN, so it stays live even if someone takes your phone. A short video from your rear camera follows as a second text. BAC MONITORING Self-test with the SOBRDRIVE breathalyzer, see your result instantly, and keep a private history of your tests. SOBER ON START Set your own limit. A passing test unlocks your vehicle for a short window, then SOBRDRIVE re-locks automatically. Parents can set limits for teen drivers and see their history from the SOBRDRIVE portal. HEROES Add up to five people you trust. They're the ones who hear from you when PANIC fires. SOBRDRIVE is built by Driven By Safety, Inc., holder of multiple U.S. patents on Bluetooth-based voluntary DUI prevention. Requires the SOBRDRIVE module and breathalyzer, available at www.sobrdrive.com

Law Enforcement conducting DUI enforcement is imperative. According to the National Highway Traffic Safety Administration, every day, approximately 32 people in the United States die in drunk driving crashes - that's one person every 45 minutes. DUI arrests are prone to going to trial, require extensive training, and typically require the officer to complete an extensive amount of paperwork. To assist officers with making a DUI arrests, we developed DUI Assist. DUI Assist makes officers jobs easier by walking the officer through the DUI, step by step. While the officer makes their way through the app, the app has prompts for the officer to read out loud. This way the officer is clear and consistent with their instructions. DUI Assist has built-in timers and tools to assist with field sobriety exercises. When the officer has completed going through the steps on DUI Assist, the officer can export the notes to a PDF. Agencies are able to work with DUI Assist to export the data from DUI Assist, directly to their arrest packet.
