In North Carolina, there is an ignition interlock restriction for certain drivers, which requires them to blow into the ignition interlock device themselves. It is not allowed to have someone else blow into the device in order to cheat the system. Currently, no cameras are attached to the devices, but this technological advancement is expected to be implemented soon. The camera would take a picture while the driver is blowing into the device. Although there is no physical barrier preventing someone else from starting the car for the driver, if there is another person present who does not have alcohol on their breath, it would be logical to let them drive.
