The defendant, Donald J. Mahoney, was convicted of operating a motor vehicle while under the influ *526 ence of intoxicating liquor in violation of G. L. c. 90, § 24 (1984 ed.). The defendant appealed, and we transferred the case to this court on our own motion.
Testimony at trial before a jury of six produced the following facts. At approximately 12:46 a.m. on March 17, 1985, Worcester police officer Frank Cummings arrived at the scene of an accident involving two automobiles. After ascertaining that no medical attention was required at the scene, Officer Cummings approached the defendant’s automobile and detected the odor of alcohol. Upon questioning the defendant, Officer Cummings had some difficulty understanding the defendant due to the defendant’s slurred speech. When the defendant stepped from his automobile, he stumbled and subsequently had difficulty walking to the front of the vehicle. The defendant did not respond when asked to perform two field sobriety tests. Officer Cummings then determined that, in his opinion, the defendant was under the influence of alcohol and placed the defendant under arrest.
The defendant was taken to the police station where the booking procedure was videotaped. At that time, the defendant was coherent and responsive. Later, being advised of his rights under G. L. c. 263, § 5A, the defendant was given a breathalyzer test and a reading of .19 resulted.
1. The defendant first argues that the videotape of the booking procedure was erroneously admitted in evidence and played before the jury in violation of the Fourth, Fifth, and Sixth Amendments to the Constitution of the United States and his rights under
Miranda
v.
Arizona,
We have stated that videotapes are “on balance, a reliable evidentiary resource.”
Commonwealth
v.
Harvey,
No Fourth Amendment violation occurred because no search or seizure was involved in videotaping the defendant. The booking procedure took place in an open area of the police station where any officers or passersby could observe the defendant. See
United States
v.
Dionisio,
There was also no violation of the defendant’s Fifth Amendment rights. The defendant’s right not to be compelled to be a witness against himself does not extend to photographic or video recordings, but is limited only to evidence that is “testimonial” or “communicative” in nature. See
Schmerber
v.
California,
The defendant’s arguments that his Sixth Amendment rights were violated must also fail. Our cases make clear that the Sixth Amendment right to counsel does not apply at the time
*529
of an arrest.
Commonwealth
v.
Mandeville,
Finally, the defendant argues that the videotape was not properly authenticated because the Commonwealth did not present evidence to show that there were properly promulgated rules and regulations concerning the videotape procedure or that the operator of the videotape equipment was competent or experienced in the use of the equipment. See
People
v.
Strozier,
2. The defendant next claims that the judge erred in limiting the scope of defense counsel’s opening statement. The Commonwealth indicated in its opening statement that it would introduce the videotape of the defendant recorded during the booking procedure. When defense counsel commented that jurors should pay particular attention to certain actions of the defendant while viewing the videotape, the Commonwealth objected and the judge cautioned defense counsel that he was bordering on argument. When counsel returned to commenting on the videotape and what the jurors would not see, the Commonwealth again objected and the judge instructed counsel to focus only on evidence that he intended to offer. The judge further instructed counsel not to comment on the videotape. We conclude that there was no error.
“The proper function of an opening is to outline in a general way the nature of the case which the counsel expects to be able to prove or support by evidence.”
Commonwealth
v.
Fazio,
3. The defendant also alleges error by the judge in restricting his cross-examination of the arresting officer. The judge sus
*531
tained an objection by the Commonwealth when defense counsel asked Officer Cummings whether he was aware of other instances in which videotapes of the booking procedure had been used in a trial where the charge was driving under the influence of intoxicating liquor. The defendant argues on appeal that this cross-examination was proper because it would have placed the jury in a better position to assess the value and weight to be given to the videotape. Again, the judge did not abuse his discretion in limiting the scope of cross-examination.
Commonwealth
v.
Maltais,
4. On direct examination, the defendant testified that at the time of the incident he was taking an antidepressant medication called Nardil. The defendant argues that the judge erred in allowing the Commonwealth to ask the defendant on cross-examination, and over the objection of the defendant, whether he was aware that he was not to drink alcohol while taking Nardil. The defendant responded that he was not aware of any limitation. On appeal, he maintains that the question was improper because it contained prejudicial information which was not based on the evidence. There was no showing that the prosecutor acted in bad faith in asking this question, “implying the truth of a proposition he knew to be false.”
Commonwealth
v.
Fitzgerald,
5. Finally, the defendant maintains that the Commonwealth improperly stated during closing argument that a reading of .19 by a breathalyzer was almost twice as much or even nine points above the limit of . 10 at which the jury could draw the inference that the defendant was intoxicated. Even assuming that the statement by the prosecutor was erroneous, there was no prejudice. The defendant objected, and the judge stated that he would instruct the jury on this issue. The totality of the charge cured any possible prejudice to the defendant which may have occurred during the Commonwealth’s closing argument.
The defendant also claims that the judge improperly instructed the jury when he stated: “Above . 10 the jury is entitled to draw the inference that he was under the influence of alcohol — . 10 or above. The machine is calibrated to say at this point the person was under the influence of alcohol.” While G. L. c. 90, § 24 (1)
(e),
speaks in terms of a “presumption” that a defendant was under the influence of intoxicating liquor if the percentage, by weight, of alcohol in the defendant’s blood was .10 or greater, we have interpreted the statute as creating a “permissible inference” which the jury may employ in determining whether a defendant was intoxicated.
Commonwealth
v.
Moreira,
Judgment affirmed.
Notes
The defendant’s brief also refers to the Declaration of Rights of the Massachusetts Constitution and to the Fourteenth Amendment to the Constitution of the United States. Because the defendant’s arguments focus on the provisions discussed within the text, we do not address the merits of any possible arguments on his behalf under these additional provisions. See Mass. R. A. P. 16 (a) (4), as amended,
In addition to stating that “[a]bave .10 the jury is entitled to draw the inference that he was under the influence of alcohol,” the judge also in- *533 strutted the jury that the breathalyzer reading was “something that you should consider along with all the rest of the evidence in making your decision. It isn’t something, of course, that you have to follow; but you must — you should consider this along with all the other evidence in making your decision being just as fair as you can to both parties and decide whether or not the defendant was under the influence of alcohol.” In light of these statements, we conclude that the jury were properly instructed that a breathalyzer reading of .19 entitled them to draw the inference that the defendant was intoxicated but did not require that they make such a finding.
