What is the maximum blood alcohol content allowed for the vehicle to start if you have an Ignition Interlock Device?

The correct answer is based on the regulations surrounding the use of an Ignition Interlock Device (IID) after a driving under the influence (DUI) conviction. In Massachusetts, individuals who are required to have an IID installed in their vehicle must not have a blood alcohol content (BAC) level that exceeds 0.02 at the time of starting the vehicle.

This lower threshold is designed to ensure that drivers maintain a significantly sober state while operating a vehicle, given their previous offenses. It reflects a strict approach to reducing the risk of repeat offenses and enhancing safety on the roads.

Understanding this limit is crucial for anyone who has been mandated to use an IID, as exceeding this limit would prevent the vehicle from starting and could result in penalties or further legal consequences.
