A first OUI in Massachusetts: what it can result in

Verified · next review

A wide range, and two assessments the court cannot waive. Massachusetts writes the first OUI as one broad band rather than a graded floor: a fine of not less than $500 nor more than $5,000, or imprisonment for not more than two and a half years, or both. There is no mandatory minimum in the sentence itself. What is mandatory sits beside it. A $250 assessment goes to the Head Injury Treatment Services Trust Fund and the statute says it shall not be subject to reduction or waiver by the court for any reason. A second $50 assessment goes to the Victims of Drunk Driving Trust Fund and likewise cannot be waived. Both attach not only on conviction but also on probation, on a continuance without a finding, and on an admission to sufficient facts — which is to say they attach on the dispositions first offenders usually take, including the alternative disposition the same section cross-references at § 24D.

Written any number of ways — a 1st offense OUI, OUI 1st, OUI first offense MA, or a first OUI in MA — and the paperwork will use none of them. Massachusetts charges it under a section number, and that is what decides the range below.

The other half of the sentence

The device is a separate track

Massachusetts marks the license itself — "HT" for a hardship license with interlock, "T" for interlock alone — expressly so that officers can identify these drivers at a stop. The program came out of Melanie’s Law in 2005 and is run by the Driver Control Unit of the RMV.

In Massachusetts the interlock term runs Only at 0.15%+ and is administered by Massachusetts RMV, Driver Control Unit — which is why a plea that settles the criminal case does not settle the device. What counts as a violation on it, and what an agency adds to the term, is its own arithmetic: violations and lockouts. Getting it off at the end is a procedure of its own too — removal and waivers.

Massachusetts OUI questions

Is jail time mandatory for a 1st OUI in Massachusetts?

Massachusetts writes the first OUI as one broad band rather than a graded floor: a fine of not less than $500 nor more than $5,000, or imprisonment for not more than two and a half years, or both. There is no mandatory minimum in the sentence itself. What is mandatory sits beside it. A $250 assessment goes to the Head Injury Treatment Services Trust Fund and the statute says it shall not be subject to reduction or waiver by the court for any reason. A second $50 assessment goes to the Victims of Drunk Driving Trust Fund and likewise cannot be waived. Both attach not only on conviction but also on probation, on a continuance without a finding, and on an admission to sufficient facts — which is to say they attach on the dispositions first offenders usually take, including the alternative disposition the same section cross-references at § 24D.

How likely is jail time for a first OUI in MA?

Start from what the statute forces and what it leaves to the judge. The floor here is up to two and a half years. Everything above that floor is argued, and the same conviction can end up served in custody, on work release or as a condition of probation depending on the county and the judge. What no one can promise you is a sentence below the statutory minimum — that is not a question of persuasion.

What is the punishment range for a 1st OUI in Massachusetts?

Misdemeanor: up to two and a half years, and a fine of $500 to $5,000. The range is set by Mass. Gen. Laws ch. 90, § 24(1)(a)(1); § 24D, and the figures on this page come from the statute rather than from a summary of it.

Does an interlock come with it in Massachusetts?

Massachusetts marks the license itself — "HT" for a hardship license with interlock, "T" for interlock alone — expressly so that officers can identify these drivers at a stop. The program came out of Melanie’s Law in 2005 and is run by the Driver Control Unit of the RMV. The device requirement and the criminal penalty are separate tracks: one is handled by the court, the other by Massachusetts RMV, Driver Control Unit.

Other steps in Massachusetts: when it becomes a felony penalties and second offense penalties.

Requesting a consultation connects you with an independent attorney or a legal referral service, who decide separately whether to take your case. Case outcomes depend on facts we do not know, and no result is ever promised.
