The primary responsibility of every driver is the safe operation of their vehicle. While traveling, mobile communication devices should be used only when the motor vehicle is at a complete stop, off the traveled portion of the roadway. Do not text and drive (it's against the law) or use this app while driving. App developed by Castle Rock Associates https://www.castlerockits.com.
