If your administrator has enabled the Emergency Unlock feature, you have the option to use this to unlock your phone in case of emergency. The Emergency Unlock button is found on the LifeSaver lock screen. To use the Emergency Unlock feature you simply need to tap the Emergency Unlock button from the LifeSaver lock screen. This will allow you inside the lock screen so you can make an emergency phone call.
Note: This feature is intended for Emergency Use only as you should refrain from using your phone while driving. A violation is recorded when you use this feature and it can also detract from your overall score.
