A system for minimizing driver distractions from a mobile device can include a blocking device and a blocking engine. The blocking device can include a first end, a second end, a cable, and a control board. The first end can include a first connector for coupling to a first port of a mobile device. The second end can include a second connector for coupling to a second port of a vehicle to receive a power signal from the vehicle. The cable can connect the first end to the second end. The control board can determine when movement of the vehicle exceeds a threshold value and transmit a launch signal. The blocking engine can receive the launch signal from the control board and launch a mobile application on the mobile device.
