A self-contained safety and security system and method that performs the multiple functions of theft deterrence, battery saving, battery analysis system, accident protection, and telemetry and control data communication for vehicles is disclosed. The electronically-based system for a vehicle having an existing power transmission circuit including a battery that can be readily installed and made operational by an individual having no special training using common household tools. The system requires the installation of no dedicated wiring in the vehicle. Furthermore, the system preferably installs without any cutting or splicing of the wiring in the vehicle's electrical system. The system preferably includes an electrical activity sensor sensing electrical activity on the power transmission circuit, a motion sensor sensing vibration associated with the vehicle, a battery-disconnect switch, and a controller to receive signals from the electrical activity and motion sensors and control the switch.
