Can the interlock system be bypassed by another person breathing into the device?

No. At random intervals after the engine has been started, the device will require additional breath samples. If a sample is not provided or if the blood alcohol concentration is 0.025 percent or higher, the device will record the event, warn the driver and then start an alarm (horn honking and/or a loud interior alarm) until either the ignition is turned off or a clean breath sample is provided. Additionally, some of the devices have built-in cameras and keep a photographic record of who provides the breath sample.
