It’s standard to have your license suspended if you’ve been convicted of driving under the influence (DUI), but some states also mandate that you have an ignition interlock system installed in your vehicle. Along with helping get you back on the right side of the law, this device also protects other drivers from potentially harmful situations. Here are a few things you can expect from driving with this device.

What to Know About Ignition Interlock Systems

What is an ignition interlock system?

This system acts as a breathalyzer for a DUI offender’s vehicle. It connects to their car’s ignition and measures their blood alcohol concentration (BAC) using a sample from the mouthpiece attached to the device. The engine will only ignite if the BAC is below the legal standard, which is .08% in most states.

When do I need to install one?

ignition interlock systemsYou’re required to install an ignition interlock system if you’ve been convicted of a DUI and you’ve had your license temporarily revoked or suspended. Once you’re legally allowed to resume driving, you’re then permitted to apply for a restricted license that only allows you to operate a vehicle if you install a device in your car.

What data does it track?

Breath sample data is regularly transmitted and reported to your state’s monitoring agency. Devices also track user activity like how many times you succeed or fail a breath test as well as GPS information like car mileage and where you travel to.

How long do I need one?

This depends on your state’s ignition interlock laws and the amount of DUIs you’ve been convicted of within a certain time frame. For example, Tennessee requires a device for the entire duration of your restricted license plus six months after your license revocation has expired. The duration ranges from a year and a half for your first DUI offense up to eight years for four or more DUIs.

What happens if I fail a breath test?

Ignition interlock systems won’t allow your car to start if you fail a breath test. Some models even initiate a temporary lockout for a few minutes before you can submit another breath sample. Your device will go into a service lockdown if you fail too many breath tests. If this happens, you’ll have to have your car towed to a local service center for further assistance.
