A control device for a powered vehicle comprising: a communications unit operable to receive vehicle control signals from a remote computer, and a control unit coupled to the communications unit, to a fuel pump of the vehicle and to an ignition system of the vehicle, the control unit comprising: fuel pump switching means, and an ignition system switching means operable to control the supply of power to the ignition system to activate and deactivate the ignition system such that the vehicle is immobilised and mobilised in response to a vehicle control signal from the remote computer, and vehicle position tracking means operable to capture real time location data for the vehicle and to transmit the location data to the remote computer to display a current location of the vehicle, wherein the fuel pump switching means is operable, in response to a user clicking a cut fuel pump button or icon within an application interface, to activate and deactivate power supply to the fuel pump of the vehicle such that movement of the vehicle is controlled by a command to incrementally slow and bring the vehicle to a gradual stop in response to a vehicle control signal received by the communications unit, in which power to the fuel pump is activated and deactivated at timed intervals using a square wave digital signal which turns on and off a relay switch attached to the power supply of the fuel pump to thereby turn the power supply to the fuel pump on and off a number of times and the fuel pump ends in the off position, and whereby once stopped the vehicle will no longer be able to be started due to there being no power to the fuel pump, a signal confirming that the vehicle has been stopped is transmitted from the communications unit to the remote computer; and in which the fuel pump is reactivated when a de-immobilisation command is sent to the control device. a communications unit operable to receive vehicle control signals from a remote computer, and a control unit coupled to the communications unit, to a fuel pump of the vehicle and to an ignition system of the vehicle, the control unit comprising: fuel pump switching means, and an ignition system switching means operable to control the supply of power to the ignition system to activate and deactivate the ignition system such that the vehicle is immobilised and mobilised in response to a vehicle control signal from the remote computer, and vehicle position tracking means operable to capture real time location data for the vehicle and to transmit the location data to the remote computer to display a current location of the vehicle, wherein the fuel pump switching means is operable, in response to a user clicking a cut fuel pump button or icon within an application interface, to activate and deactivate power supply to the fuel pump of the vehicle such that movement of the vehicle is controlled by a command to incrementally slow and bring the vehicle to a gradual stop in response to a vehicle control signal received by the communications unit, in which power to the fuel pump is activated and deactivated at timed intervals using a square wave digital signal which turns on and off a relay switch attached to the power supply of the fuel pump to thereby turn the power supply to the fuel pump on and off a number of times and the fuel pump ends in the off position, and whereby once stopped the vehicle will no longer be able to be started due to there being no power to the fuel pump, a signal confirming that the vehicle has been stopped is transmitted from the communications unit to the remote computer;
