OUI Roadblocks in Maine: No Checkpoint Statute, but Passing One Is a Class C Crime

The absence is provable rather than assumed. The Office of the Revisor of Statutes publishes a full-text search over the Maine Revised Statutes, current through October 1, 2025 and the First Special Session of the 132nd Legislature. The quoted terms "checkpoint" and "sobriety checkpoint" return no sections. The singular "roadblock" returns 29-A MRS §2414, 12 MRS §10651 and the habitual offender sections at 29-A MRS §2551-A and §2558; the plural "roadblocks" returns only 26 MRS §786 in the labour title. So Maine has neither an authorising scheme with siting, publicity and supervision requirements of the kind some states enacted, nor a prohibition, nor a legislative standard a driver could measure a particular stop against.

What Maine has instead is a statute that assumes police roadblocks exist and criminalises running one. Section 2414 of Title 29-A opens with definitions, and subsection 1 paragraph A is the operative one: "Roadblock" means a vehicle, a physical barrier or other obstruction placed on a way at the direction of a law enforcement officer. Paragraph B defines "Signal" to include, but not be limited to, the use of a hand signal, siren or flashing emergency lights. Subsection 2 makes it a Class E crime to fail or refuse to stop a motor vehicle on the request or signal of a uniformed law enforcement officer, so the ordinary duty to stop turns on the uniform rather than on the marking of the vehicle. Subsection 4 goes further for the roadblock case: a person commits a Class C crime who, without authorization, operates or attempts to operate a motor vehicle past a clearly identifiable police roadblock. The qualifier "clearly identifiable" is doing real work, because it is the only statutory quality control Maine imposes on how a roadblock is set up.

The section also carries an escalation ladder and one administrative duty. Subsection 3 makes it a Class C crime to attempt to elude an officer after being requested or signalled to stop by operating at a reckless rate of speed resulting in a high-speed chase between the operator's vehicle and a law enforcement vehicle using a blue light and siren. Subsection 6 raises eluding to a Class B crime where another person suffers serious bodily injury as defined in 17-A MRS §2(23), and subsection 7 does the same where a person passes or attempts to pass a roadblock and another person suffers serious bodily injury. Subsection 5 requires all state, county and municipal law enforcement agencies to adopt written policies on high-speed chases; Maine imposes no parallel statutory duty to adopt a written roadblock policy, which is a gap worth noting because in other states that document is where checkpoint procedure lives.

Maine repeats the pattern outside Title 29-A. Under 12 MRS §10651(1)(E)(1), attempting to elude a law enforcement officer by operating or attempting to operate an all-terrain vehicle or snowmobile past a clearly identifiable police roadblock is an offence, and §10651(2) makes it a Class D crime for which a minimum fine of not less than $1,000 must be adjudged. That is a heavier mandatory floor than the Class C motor vehicle offence carries, and it shows the Legislature using the same roadblock concept twice without ever defining when one may be established.

What happens after the stop is legislated in detail, and this is where a Maine driver's real exposure sits. The offence itself is at 29-A MRS §2411(1-A)(A): a person commits OUI by operating a motor vehicle while under the influence of intoxicants, or while having an alcohol level of 0.08 grams or more of alcohol per 100 millilitres of blood or 210 litres of breath. Section 2411(5) makes a first violation a Class D crime that is a strict liability crime as defined in 17-A MRS §34(4-A), with minimum penalties that may not be suspended: a fine of not less than $500, rising to not less than $600 where the person failed to submit to a test, and a court-ordered licence suspension of 150 days. A second offence within 10 years carries a minimum fine of $700, or $900 on a failure to test; a third carries $1,100 or $1,400 and is a Class C crime; a fourth or later carries $2,100 or $2,500. Where the operation in fact causes serious bodily injury the offence is Class C with at least 6 months of incarceration, a fine of not less than $2,100 and a 6-year suspension, and where it causes death the offence is Class B with at least 6 months, a fine of not less than $2,100 and a 10-year suspension.

Testing is compulsory rather than consensual once the threshold is met. Section 2521(1) provides that if there is probable cause to believe a person has operated a motor vehicle while under the influence of intoxicants, that person shall submit to and complete a test to determine an alcohol level and the presence of a drug or drug metabolite by analysis of blood, breath or urine. Under §2521(2) the officer must administer a breath test unless the officer determines a breath test is unreasonable, in which case another chemical test is administered instead, and for a blood test the operator may choose a physician if one is reasonably available. Section 2521(3) requires a warning before a refusal can be used: the person must first be told that refusal or failure to complete will result in suspension of the licence for a period up to 6 years, will be admissible in evidence at an OUI trial, and will be considered an aggravating factor at sentencing subjecting the person to a mandatory minimum period of incarceration. Section 2521(4) then limits the value of that warning, providing that a test result may not be excluded solely because the officer failed to comply with the subsection 3 notice. Section 2521(5) requires the Secretary of State to suspend immediately, and §2521(6) sets the schedule: 275 days for a first refusal, 18 months for a second, 4 years for a third and 6 years for a fourth. Section 2521(6-A) provides for a one-year suspension on a first refusal where there is also probable cause to believe death occurred or will occur.

Failing or refusing to stop a motor vehicle on the request or signal of a uniformed law enforcement officer is a Class E crime under 29-A MRS §2414(2). Operating or attempting to operate a motor vehicle past a clearly identifiable police roadblock without authorization is a Class C crime under §2414(4), and becomes a Class B crime under §2414(7) if another person suffers serious bodily injury as a result. Eluding by reckless speed in a high-speed chase against a law enforcement vehicle using a blue light and siren is a Class C crime under §2414(3), escalating to Class B under §2414(6) on serious bodily injury.

The equivalent offence for an all-terrain vehicle or snowmobile passing a clearly identifiable police roadblock is a Class D crime under 12 MRS §10651(1)(E)(1) and (2), carrying a minimum fine of not less than $1,000. A first OUI conviction under 29-A MRS §2411 carries non-suspendable minimums of a $500 fine and a 150-day court-ordered licence suspension, with the fine floor rising to $600 where the driver failed to submit to a test. Refusing the chemical test triggers an immediate administrative suspension by the Secretary of State under §2521(5), for 275 days on a first refusal, 18 months on a second, 4 years on a third and 6 years on a fourth, and the refusal is separately admissible at trial and treated as an aggravating factor at sentencing.
