delivered the opinion of the court:
Following a bench trial in the circuit court of Du Page County, defendant, Michael M. Steiger, was convicted of driving under the influence of alcohol (Ill. Rev. Stat. 1987, ch. 951/2, par. 11 — 501) and was sentenced to 10 days in the county jail, one year’s probation, and was fined $300. Defendant appeals, contending that he did not knowingly and voluntarily waive his right to a jury trial because the trial court did not admonish him concerning or inquire into his reasons for the waiver.
On December 23, 1987, defendant was issued traffic citations alleging that he had violated local ordinances by failing to stop at a stop sign, recklessly driving his automobile, and improperly operating a motor vehicle due to excessive tire friction, in addition to the above-mentioned driving under the influence of alcohol charge.
On April 11, 1989, defendant’s case came up for trial. After his case was called, defendant’s attorney stated: “I have had a conference with my client[.] [H]e has indicated to me that his choice is to proceed to trial by your Honor, and he is tendering a waiver of trial by jury; is that correct, Michael[?]” Defendant then responded, “Yes, sir.” Defendant also signed a written jury waiver form. The trial court accepted defendant’s waiver, but did not ask defendant any questions about the reasons for the waiver and did not admonish him concerning the consequences of the waiver.
Defendant’s case then proceeded to a bench trial after which he was found guilty of driving under the influence of alcohol. Defendant’s sole contention on appeal is that he did not knowingly and voluntarily waive his right to a jury trial. In support thereof, defendant points out that the trial court failed to admonish him concerning his right to a jury trial and failed to question him about his decision to waive this right. We disagree with defendant and affirm the trial court.
We first note that defendant did not raise this issue in his post-trial motion; therefore, the issue has not been properly preserved for review. (People v. Enoch (1988),
Under the Illinois Constitution an accused is guaranteed the right to a jury trial. (Ill. Const. 1970, art. I, §8.) In addition, section 103 — 6 of the Code of Criminal Procedure of 1963 (Ill. Rev. Stat. 1987, ch. 38, par. 103 — 6) states that an accused has a right to a jury trial unless he or she understandably waives that right. Circuit courts have the duty of insuring that a defendant’s waiver of his right to a jury trial be made expressly and understandably. (Smith,
While it may be preferable for a trial court to advise a defendant of his right to a jury trial, the trial court is not constitutionally required to do so in order to maintain a valid waiver. (People v. Murrell (1975),
A defendant speaks and acts through his attorney; therefore, a trial court may rely on the defense attorney to execute his professional responsibilities. (Tucker,
In the present case, defendant spoke and acted through his attorney concerning defendant’s waiver of his right to a trial by jury. Defense counsel stated in court and on the record that he had discussed with defendant whether defendant should waive his right to a jury trial. Defense counsel then informed the court that defendant wished to waive this right and questioned defendant to determine whether defendant was still in agreement with this decision. Defendant responded in the affirmative. Therefore, under these circumstances, we find that defendant knowingly and understanding^ waived his right to a trial by jury.
We also note that defendant signed a written jury waiver form in this case. Although a signed jury waiver form alone is insufficient proof to demonstrate that the defendant made an understanding waiver of the right to a jury trial (People v. Sebag (1982),
For these reasons, the judgment of the circuit court of Du Page County is affirmed.
Affirmed.
