Carolina Law BlogMost people have heard of the ignition interlock device in NC. It’s also occasionally called the IID by the general public or even the Blow and Go or in-car breathalyzer. The interlock is a breath testing device that’s installed in your car that measures alcohol in your breath and electronically records the BAC reading.
Its purpose is to ensure you’re not drinking and driving. If you have alcohol on your breath, the vehicle won’t start. If you keep trying to start your car after consuming alcohol, eventually that will result in a “lock out” and possible administrative action by the Division of Motor Vehicles.
If you have questions about whether a “blow and go” is required, we recommend you speak to an experienced attorney immediately. Timing is often key in such matters.
