What is an interlock device?

An interlock device is a type of breath analyzer connected to a vehicle’s ignition system. When these are installed, a driver must blow a breath sample into the device in order to start the automobile. The interlock device will measure a driver’s blood alcohol content and will not allow the vehicle to start if the reading is high enough to suggest that impairment is likely. The idea behind this device is that it can help to prevent drunk driving accidents.

For more information regarding interlock devices and drunk driving charges if you have been arrested for DWI, contact the Raleigh DWI defense attorneys at the law offices of Jim Black at 919-600-4609.


"Jim, I just wanted to thank you again for everything you did for me. I am very happy about the outcome and would recommend you to anyone and everyone who has a DUI case. Two things that stuck out the most is your patience and honesty, you wanted the best for me and that was obvious."
