In these two companion cases we are asked to determine the applicability of the Fifth and Fourteenth Amendments to the United States Constitution and art. 12 of the Declaration of Rights of the Constitution of the Commonwealth, in circumstances involving the performance of breathalyzer and field sobriety tests administered for the purpose of determining whether a driver of a motor vehicle is under the influence of intoxicating liquors. We conclude that neither the Fourteenth Amendment nor art. 12 is violated by the administration of these tests.
The facts of these cases may be briefly stated. The defendant Brennan was arrested and charged with operating a motor vehicle under the influence of alcohol, speeding, and failure to operate within marked lanes. After being warned of his Miranda rights, he told the рolice officer, “I will not say anything or do anything until my lawyer is present.” He was then taken to a police station, whereupon he was asked if he would agree to submit to a field sobriety test and a breathalyzer test. He was advised that a refusal to take the breathalyzer test would result in the automatic suspension of his driver’s license for ninety days. See G. L. c. 90, § 24 (1) (f). 1 Brennan agreed to and did take the breathalyzer *774 and field sobriety tests. The field sobriety tests consisted оf the so-called finger-to-nose test, picking up coins from the floor, and walking a straight line. Brennan was also asked certain questions relating to his alleged intoxication, and to some of these he gave incriminating answers.
Before trial, Brennan moved to suppress “any and all statements and evidence attributed to” himself. At the hearing on the motion to suppress, Brennan testified that the consequenсe of license suspension for failure to submit to a breathalyzer test induced him to take the test. A District Court judge allowed his motion to suppress on the theory that the case was governed by the principles established in
Miranda
v.
Arizona,
The defendant Floyd W. Knockel was also arrested and charged with operating a motor vehicle whilе under the influence of alcohol, and was also advised that his refusal to take a breathalyzer test would result in the suspension of his license. He took the breathalyzer test, and later, at a hearing on his motion to suppress the results of the test, he too testified that he submitted to the testing procedure in order to avoid the suspension of his license. The District Court judge, pursuant to Mass. R. Grim. P. 34,
1. The Privilege Against Self-incrimination Under the United States Constitution.
We first dispose of any suggestion that the oral statements made by Brennan to the police are admissible. The statements were clearly elicited in violation of the requirements set forth in
Miranda
v.
Arizona,
*776
Brennan contends that his rights under the Fifth and Fourteenth Amendments were violated when the police asked him to take the breathalyzer and field sobriety tests after he expressed a desire to remain silent and to see his lawyer.

See
Miranda
v.
Arizona, supra
at 473-474. The privilege of the accused not to be compelled to be a witness against himself, however, protects only against the compulsion of “communications,” or “testimony.” It does not bar compulsion “which makes a suspect or accused the source of ‘real or physical evidence.’”
Schmerber
v.
California,
With respect to the breathalyzer test, we see no distinction between this type of test and the blood test involved in the
Schmerber
case. A breathalyzer test is no more communicative or testimonial than a blood test, and it is certainly a less intrusive method of obtaining evidence. The fact that the breathalyzer test requires a greater degree of participation is not a distinguishing factor, as is suggested. Accord,
State
v.
Driver,
A somewhat closer question is presented with respect to fiеld sobriety tests. Such tests enable an observer to draw an inference as to guilt or innocence directly from the subject’s ability to perform the acts required of him. Arguably, the suspect’s actions have, in the circumstances, a communicative quality to them. This has led at least one court to conclude that field sobriety tests are subject to the protections afforded by the Fifth Amendment. See
People
v.
McLaren,
The United States Supreme Court has consistently indicated that evidence that is “testimonial” or “communicative” in nature is that which reveals the subjective knowledge or thought processes of the subject. In
Schmerber, supra
at 761 n.5, the Court referred to a nod or head-shake
as
“testimonial,” and indicated that “[s]ome tests seemingly directed to obtain ‘physical evidence,’ for example, lie detector tests measuring changes in body function during
*778
interrogation, may actually be directed to eliciting responses which are essentially testimonial.”
Id.
at 764. On the other hand, the Court in
Schmerber
appeared to accept as correct those cases holding that the privilege offers no protection against compulsion to submit to “fingerprinting, photographing, or measurements, to write or speak for identification, to appear in court, to stand, to assume a stance, to walk, or to make a particular gesture” (footnote omitted).
Id.
See
United States
v.
Wade,
Our discussion in
Commonwealth
v.
Hughes,
*779
Field sobriety tests, on the other hand, are not intended to reveal any thoughts or knowledge of the subject. Other courts have observed that such tests are based upon the relationship between intoxication and the loss of coordination which intoxication produces. They do not compel the subject to reveal his knowledge or thoughts. They only force him to exhibit his physical сoordination, or lack thereof, for observation by a police officer.

v.
Ramirez,
2. The Privilege Against Self-incrimination Under Art. 12.
The defendants argue that even if the use of the results of breathalyzer and field sobriety tests is not prohibited by the United States Constitution, it is prohibited by the seemingly broader language of art. 12. Article 12 provides in part that no person shall “be compelled to accuse, or furnish evidence against himself.” As a preliminary matter, the Commonwealth in the Knockel case asserts that art. 12 has no application here because the defendant was not “compelled” to take the breathalyzer test, rather he was given a “choiсe” under G. L. c. 90, § 24 (1) If) — that of taking the breathalyzer test or suffering the suspension of his driver’s license for ninety days. We assume, for the purposes of this case, that the “choice” offered by § 24 (1) (f) constitutes compulsion sufficient to invoke art. 12.
The defendants assert that the natural meaning of the words “furnish evidence” encompasses real or physical evidence as well as testimonial or purely communicative evidence, and that art. 12 therefore rеquires a more expansive interpretation than that given the Fifth Amendment. 6 This court is, of course, free to interpret the provisions of art. 12 *780 so as to extend its protections beyond those recognized under the Fifth Amendment. In the circumstances of this case, however, we decline to do so. A purely literal construction of art. 12 would forbid the compelled production of any evidence furnished by thе defendant. Conceivably, this could apply to fingerprints, photographs, lineups, blood samples, handwriting and voice exemplars, and indeed, even the appearance of the defendant at trial for identification purposes. We doubt that the framers of our State' Constitution intended art. 12 to prohibit these common methods of identification.
It has been said that art. 12 and the many similar constitutiоnal provisions of other States merely restated the common law rule against self-incrimination.
Commonwealth
v.
Joyce,
To the extent that cases of this court have addressed the issue, they are consistent with this interpretation. In
Commonwealth
v.
DiStasio,
The
DiStasio
and
Burke
cases indicate an acceptance by this court of the principle that the privilege against self-incrimination as expressed in art. 12 does not extend to non-
*782
communicative evidence. This is in acсord with the majority of other States that have considered the question, many of which have constitutional provisions similar to ours. 8 J. Wigmore,

We believe it represents the sounder view. While it is true that some of the policies that underlie the privilege might warrant its application to a broader class of cases than ordinarily falls within its reach, “the privilege has never been given the full scope which thе values it helps to protect suggest.”
Schmerber
v.
California,
The order of the District Court judge allowing the defendant Brennan’s motion to suppress is reversed in so far as it relates to the results оf the breathalyzer and field sobriety tests. So much of the order as suppresses Brennan’s oral statements made to the police while in custody is affirmed. To question one reported by the District Court judge in Knockel’s case, we answer, “No.” To question two we answer that art. 12 of the Massachusetts Declaration of Rights precludes only the compelled production of “testimonial” evidence. As tо a request for costs and expenses made by the defendant Brennan pursuant to Mass. R. Crim. P. 15 (d),
So ordered.
Notes
General Laws c. 90, § 24 (1) (f), as amended through St. 1980, c. 383, § 2, commonly known as the implied consent law, provides: “Whoever operates a motor vehicle upon any [public] way . . . shall be deemed to have consented to submit to a chemical test or analysis of his breath or blood in the event that he is arrested for operating a motor vehicle while under the influence of intoxicating liquor .... If the person arrested refuses to submit to such test or analysis, after having been informed that his license ... to operate motor vehicles ... in the commonwealth shall be suspended for a period of ninety days for such refusal, no such test or analysis shall be made, but the police officer before whom such refusal was made shall immediately prepare a written report of such refusal .... [which] shall be endorsed by a third person who shall have witnessed such refusal .... [and] shall be sworn to under the penalties of perjury by the police officer before whom such refusal was made .... [It] shall set forth the grounds for the officer’s belief that the person ar *774 rested hаd been driving a motor vehicle . . . while under the influence of intoxicating liquor, and shall state that such person had refused to submit to such chemical test or analysis when requested by such police officer to do so. Each such report shall be endorsed by the police chief . . . and shall be sent forthwith to the registrar. Upon receipt of such report, the registrar shall suspend any license ... to operate motor vehicles issued to such person ... for a period of ninety days.”
The statute was upheld against a challenge under the due process clause of the Fourteenth Amendment in
