The defendant was found guilty by a District Court jury of the charge of operating a motor vehicle while under the influence of intoxicating liquor in violation of G. L. c. 90, § 24. The defendant alleges error in (1) the admission of statements he made to police in the course of the roadside stop, and (2) the judge’s instruction to the jury pursuant to G. L. c. 90, § 24(l)(e), concerning the absence of blood alcohol evidence. We decide that the instruction constituted reversible error in this case.
We summarize the pertinent evidence adduced at trial. The two arresting police officers testified that they had observed the defendant at the scene. Through them evidence was presented that the defendant was unsteady on his feet, his eyes were “glossy” [sfc] and “watery,” his breath had a strong odor of alcohol, and his speech was slurred. The officers described the defendant as verbally abusive and belligerent. Each of the police officers testified that he formed an opinion, at the time of arrest, that the defendant was under the influence of alcohol. An emergency medical technician who observed the defendant at the police station in response to his request for medical treatment likewise testified that he formed the opinion that the defendant was intoxicated at the time of his arrest.
The police officers were also permitted to testify to statements made by the defendant during the roadside stop.1 When asked by an officer where he was coming from, the defendant replied, “I had a couple drinks.” One of the officers requested that the defendant perform a field sobriety test which he refused stating that he “didn’t want to take any test.” At the conclusion of all this evidence, the judge instructed the jury as required by G. L. c. 90, § 24(l)(e), to which the defendant did not object. The jury returned a verdict of guilty, and the defendant was sentenced to one year in the Essex County house of correction, six months to be served, with six months suspended.
*2081. Denial of defendant’s motion to suppress. The question regarding the defendant’s whereabouts prior to the stop constituted “[gjeneral on-the-scene questioning” by the officer and did not require the officer to administer Miranda warnings. Commonwealth v. McNelley, 28 Mass. App. Ct. 985, 986 (1990), quoting from Commonwealth v. Merritt, 14 Mass. App. Ct. 601, 604 (1982). The facts surrounding the inquiry demonstrate that the questioning was part of a temporary routine traffic stop and did not amount to a custodial investigation. See Berkemer v. McCarty, 468 U.S. 420, 440 (1984). Only a brief period of time elapsed between the initial stop of the defendant’s car and the officer’s question,2 and the encounter took place in the “public view” on the side of the roadway, an atmosphere far less coercive than the station house. See Commonwealth v. McNelley, supra at 986; Commonwealth v. Ayre, 31 Mass. App. Ct. 17, 20 (1991); Commonwealth v. Smith, 35 Mass. App. Ct. 655, 657-658 (1993). Similarly, the officer’s request that the defendant perform the field sobriety test did not, in the circumstances, subject the defendant to custodial interrogation or entitle him, at that point, to Miranda warnings. See Commonwealth v. Ayre, 31 Mass. App. Ct. at 20-21.
2. The erroneous instruction. The defendant contends that the judge violated his privilege against self-incrimination contained in art. 12 of the Massachusetts Declaration of Rights by instructing the jury as mandated by G. L. c. 90, § 24(l)(e). The Commonwealth argues the instruction was not a violation of art. 12; but if so, any error did not create a substantial risk of a miscarriage of justice under the circumstances, the standard it asserts applies. We hold that Commonwealth v. Zevitas, 418 Mass. 677 (1994), controls the present case in all respects and requires us to find reversible error.
*209We conclude that the new rule announced in Commonwealth v. Zevitas, supra, that the mandatory jury instruction “unconstitutionally compels an accused to furnish evidence against himself,” id. at 683, citing Opinion of the Justices, 412 Mass. 1201, 1211 (1992); see also Commonwealth v. Lydon, 413 Mass. 309, 314-315 (1992), should be applied retroactively to this case. “Retroactive application of a rule of criminal law is indicated if (1) a case is on direct appeal . . . when the new rule is announced, and (2) the issue was preserved at trial.” Commonwealth v. Figueroa, 413 Mass. 193, 202 (1992), quoting from Commonwealth v. Libran, 405 Mass. 634, 645 (1989). The defendant’s direct appeal was pending at the time the Zevitas rule was announced. In addition, the defendant is entitled to the benefit of the new rule even though he failed to object to the instruction at trial because “the constitutional theory on which the defendant has relied was not sufficiently developed at the time of trial . . . to afford the defendant a genuine opportunity to raise his claim at [that] juncture[] of the case.” Commonwealth v. Rembiszewski, 391 Mass. 123, 126 (1984). See also DeJoinville v. Commonwealth, 381 Mass. 246, 248 (1980).3 The defendant’s constitutional claim is considered “as if it were here for review in the regular course,” Commonwealth v. Rembiszewski, 391 Mass. at 126, quoting from Commonwealth v. Kater, 388 Mass. 519, 533 (1983), and, therefore, we must decide whether the Commonwealth has demonstrated that the error claimed was harmless beyond a reasonable doubt. See Commonwealth v. Curtis, 417 Mass. 619, 635 (1994). Contrast Commonwealth v. Lydon, 413 Mass. at 313.
*210We cannot say that the jury refrained from concluding that the defendant had refused to submit to a blood alcohol test despite the judge’s warnings against drawing any inferences for or against either party from the lack of evidence at trial. Commonwealth v. Zevitas, 418 Mass. at 683-684. We further cannot conclude beyond a reasonable doubt that the jury did not use this evidence against the defendant in violation of his art. 12 rights. Id. at 684. See also Commonwealth v. Perrot, 407 Mass. 539, 549 (1990). “Where the prejudicial remarks fall from the judge himself, the effect on the jury is likely to be more damaging [than the erroneous admission of testimony] . . . .” Commonwealth v. Zevitas, 418 Mass. at 684, quoting from Commonwealth v. Goulet, 374 Mass. 404, 414 (1978). The error in this case was not harmless beyond a reasonable doubt.
Judgment reversed.
Verdict set aside.
The defendant filed a motion to suppress certain statements on the ground that he was deprived of Miranda warnings. After a hearing, the judge denied the motion in an oral order.
The officer testified at the suppression hearing that the defendant was still in his automobile when he posed the question of the defendant’s previous whereabouts. He further testified that the time between the initial stop and the question to the defendant was “very short” and “much less” than a couple of minutes.
We do not require “lawyers to be clairvoyant and to object to instructions not yet identified as constitutional error.” Commonwealth v. Repoza, 400 Mass. 516, 520 (1987). The defendant’s trial in the present case was held on March 19 and 20, 1992. The Opinion of the Justices, supra, submitted to the Senate on May 12, 1992, was the first indication that any statement regarding the lack of blood alcohol evidence violated art. 12. The defendant relied on this opinion in attacking the instruction in his initial brief filed in April, 1994. The Zevitas decision was not issued until September 23, 1994.
