Lock-out time

Lock-out time refers to the period of time following a failed BrAC test during which a subsequent test may not be taken. Once the lock-out time has ended, the driver may make another attempt to start the vehicle. The typical timeframe for the lock-out period is a short duration of five minutes after one failed attempt or a false positive. After a first short lock-out, the device may go into long lock-out mode (e.g., 20 minutes) in case the second breath test after the short lock-out is failed as well.
