Understanding Massachusetts’ ignition interlock device laws

In addition to being embarrassing, having an ignition interlock device installed on your car or truck is costly and annoying. The device seeks to prevent motorists from operating under the influence of alcohol by making them provide breath samples before and while driving the car. Unless you produce an adequate breath sample when blowing into your device, it prevents your vehicle from starting. 

Who has to install an ignition interlock device in Massachusetts, and if you are among those that do, how long should you expect it to be there? 

Installation requirements 

The state requires that you install this device on your vehicle if you receive two or more convictions for operating under the influence of alcohol or controlled substances. You are responsible for financing all costs associated with the device, including installation and maintenance costs. As far as maintenance goes, you need to have it undergo servicing every 25-to-30 stays to stay compliant. 

Length requirements 

When you install the ignition interlock device on your vehicle, it must remain there for a minimum of two years. If you are driving again after securing a conditional hardship license, you must keep the device on your vehicle for the entirety of your license suspension plus another two years once you fully regain the right to drive. 

Removal requirements 

It is important that you know exactly when your license restriction period ends. At this point, you must apply to the Massachusetts Registry of Motor Vehicles to remove the license restriction and the ignition interlock device. 

Compliance requirements 

You must produce a breath sample that reveals a blood alcohol concentration below .02% percent for your vehicle to start. If your breath sample is insufficient, you must wait for it to decrease to try again. If you produce two unsatisfactory breath samples within the same service period, you must visit your service provider within 48 hours if you wish to use your car moving forward.
