Vehicle Searches at a Maine Traffic Stop: What §105 Lets an Officer Demand, and the Two Consent Limits Maine Wrote

The negative here is worth stating precisely, because two neighbouring states have provisions Maine does not. The Maine Cannabis Legalization Act at 28-B MRS §1501 authorises an adult 21 or older to use, possess or transport up to 2 1/2 ounces of cannabis or a combination including no more than 10 grams of concentrate, and §1501(2)(B)(1) makes consumption by the operator or a passenger in a vehicle on a public way a civil violation with a fine of not more than $100. What §1501 does not contain, anywhere, is a search clause. There is no Maine equivalent of the Michigan provision declaring that lawful conduct is not grounds for search or inspection, and no Maine odour-and-probable-cause provision. Searching the whole of the Maine Revised Statutes for the phrase "grounds for search" returns no section at all.

Maine's one express "not grounds for a search" rule is in the medical scheme rather than the adult-use one. Under 22 MRS §2430-C(8), possession of a registry identification card by a cardholder, the act of applying for one, possession of a written certification issued under §2423-B, or possession of a designation document executed under §2423-A(1)(F-1), is evidence of lawful conduct and may not be used to support the search of that person or that person's property. The same subsection is careful about its own limits: possession of or application for a card does not prevent the issuance of a warrant if probable cause exists on other grounds. It was last amended by PL 2023, c. 365, §13. Note that §2430-C(7) conditions the chapter's protections on production: a qualifying patient or visiting qualifying patient must present the written certification on the request of a law enforcement officer, and a caregiver must present the registry identification card or registration certificate.

The second express limit is a phone rule, and it is the closest thing Maine has to a statutory statement about the scope of consent given at a roadside. Section 1408 of Title 29-A requires a licensee to have the licence in immediate possession while operating and allows possession in electronic form, defined as a digital representation of the information on a physical licence held on a portable electronic device. Subsection 2 then requires the licensee to produce the licence or an electronic version on demand of a law enforcement officer, and adds that the use of a portable electronic device to provide licence information does not constitute consent for a law enforcement officer to access other contents of the portable electronic device. That sentence entered the law through PL 2017, c. 229, §30, at the same time the electronic licence was authorised.

Everything else about a Maine stop runs through 29-A MRS §105. Subsection 1 sets two conditions before a vehicle may be stopped at all: the officer must have reasonable and articulable suspicion to believe a violation of law has taken or is taking place, and the officer must be in uniform. The permitted purposes are then closed: arresting the operator for a criminal violation, issuing the appropriate written process for a criminal or civil violation or a traffic infraction, or questioning the operator or occupants. Subsection 2, headed "Scope of inspection," enumerates what an officer who has made such a stop may demand and inspect: the driver's licence, certificate of registration, permits and the identification numbers of the motor vehicle. A state police officer trained under the federal motor carrier safety rules may additionally demand and inspect the driver's record of duty status and medical examiner's certificate where applicable. Read carefully, §105(2) is a grant about documents and vehicle identification, not a search authority and not a search prohibition; Maine simply does not legislate the search itself.

What §105 does contain is a real coercive power short of a search. Subsection 3 allows an officer to impound and hold a vehicle where it is operated by a person unable to produce a certificate of registration, or by someone other than the registered owner who cannot present reasonable evidence of authority to operate it, and the vehicle is held until claimed by the registered owner or until the registered owner verifies the operator's authority. The registered owner must be notified immediately of the impoundment. Subsection 4 adds the identification duty: a person is guilty of a Class E crime where a law enforcement officer has probable cause to believe the person violated or is violating Title 29-A and the person intentionally fails or refuses upon request to give a correct name, address or date of birth.

Two further Maine points are worth keeping straight. Maine's roadside chemical testing regime is not consent in the ordinary sense: under 29-A MRS §2521(1), where there is probable cause to believe a person operated under the influence of intoxicants, that person shall submit to and complete a test of blood, breath or urine, and refusing carries a Secretary of State suspension of 275 days for a first refusal rising to 6 years for a fourth. And Maine's interception statute at 15 MRS §709(4) excludes a party to a conversation from the definition of intercept, which is why a driver may record their own exchange with an officer while a covert recording of a conversation the driver is not part of is a Class C crime under 15 MRS §710(1).

Because Maine has no consent-to-search statute, there is no statutory penalty for an improper vehicle search and no statutory suppression rule of the Maine-specific kind Maryland enacted at Crim. §1-211. The remedies are constitutional and are litigated as motions to suppress in the criminal case rather than under a code section. Where Maine does write a rule, it writes it as a limit on what an officer may rely on: 22 MRS §2430-C(8) makes a registry identification card, an application for one, a written certification under §2423-B or a designation document under §2423-A(1)(F-1) evidence of lawful conduct that may not be used to support a search, while preserving a warrant issued on probable cause from other grounds; and 29-A MRS §1408(2) makes clear that handing over a phone to show a digital licence is not consent to the rest of the device.

Refusing to identify at a Maine motor vehicle stop is a Class E crime under 29-A MRS §105(4) once the officer has probable cause of a Title 29-A violation and asks. Failing to produce a certificate of registration, or driving another person's vehicle without reasonable evidence of authority to do so, exposes the vehicle to impoundment under §105(3) until the registered owner claims it or verifies the operator's authority, with immediate notice to the owner. Consuming cannabis as the operator or a passenger in a vehicle on a public way is a civil violation under 28-B MRS §1501(2)(B)(1) and (C), with a fine of not more than $100 in addition to any other applicable penalty.
