Mass. Ignition Interlock Device Vendors

Pursuant to Melanie’s Law, G.L. c. 90 § 24 ½, the Massachusetts Registry of Motor Vehicles requires anyone with 2 or more DUI convictions or alcohol program assignments on his or her record to use the ignition interlock device during the term of any hardship license and for 2 years after getting a full license.

There are 5 authorized ignition interlock device vendors which the Registry has approved to service Massachusetts ignition interlock customers. They are as follows:

• CST Intoxalock, 1-877-777-5020
• Draeger, 1-800-332-6858

• Sens-O-Lock, 1- 888-786-7384

Ignition interlock devices sometimes register false positive readings and violations of the ignition interlock law and the Registry’s interlock regulations can result in a 10 year or lifetime license revocation.
