delivered the opinion of
the Court,
in which KELLER, P.J., and KEASLER, HERVEY, HOLCOMB, and COCHRAN, JJ., joined.The question is whether a condition that the appellant not operate a motor vehicle is one of the “reasonable conditions on bail pending the finality of his conviction” that may be imposed on bail pending appeal of his felony conviction. See Tex.Code Crim. Proc. art. 44.04(c).
I.
The appellant was indicted for committing criminally negligent homicide on May 8, 1998. About this offense, the habeas-corpus record that is now before us discloses only that the appellant was driving his commercial vehicle when he killed the victim. Before trial the appellant was released on a $2,000 cash bond. A jury found him guilty of the criminally negligent homicide and assessed a punishment of six years’ imprisonment on June 8, 1999. He immediately gave notice of appeal. The district court set his bail at $50,000 and imposed on the bail the condition that the appellant was “not to operate any type of motor vehicle whatsoever.”
*399The appellant applied for a writ of habe-as corpus on the ground that the condition was unreasonable, in violation of article 44.04(c) and “due process.” The district court issued the writ and held a hearing. The appellant testified that the condition of his bail prevented him from engaging in his business of selling “driveway road base,” which he delivered in his own truck. He admitted that, during the pendency of the indictment for criminally negligent homicide, he was involved in another “injury accident” while operating a commercial vehicle. The district court denied habeas-corpus relief, and the appellant gave notice of appeal.
A divided panel of the Court of Appeals reversed the district court’s habeas-corpus judgment. Anderer v. State, 7 S.W.3d 245 (Tex.App.—Houston [14th Dist.] 1999).1 It held that the purpose of a condition on bail pending appeal is “to assure the presence of a defendant if his or her conviction becomes final,” and that the condition in this case “does nothing to advance th[at] purpose.”2 The Court said that if the district court had good cause to believe that the appellant would not appear or was likely to commit another offense, “the proper action is to deny an appeal bond [sic ] and commit the defendant to custody.” 3 We granted review.
II.
The issue in this case turns on the meaning of the phrase, “reasonable conditions on bail pending the finality of [the defendant’s] conviction,” in article 44.04(c). As always, we begin our consideration with the language of the statute.4
*400Article 44.04 of the Code of Criminal Procedure identifies seven classes of convicted defendants. As to four classes, the trial court has no discretion.
In two of these classes, “The defendant may not be released on bail pending the appeal ..., but shall immediately be placed in custody and the bail discharged”:5
(1) “where the punishment equals or exceeds 10 years’ confinement,”6 and
(2) “where the defendant has been convicted of an offense listed under Section 3g(a)(l), Article 42.12.”7
In two other classes a convicted defendant is entitled to release on bail:
(3) the misdemeanant, who “is entitled to be released on reasonable bail,”8
(4) the felon whose conviction has been reversed by a decision of a court of appeals, who “is entitled to release on reasonable bail, regardless of the length of the term of imprisonment.”9
In the three remaining classes the trial court has discretion. These classes corn-prise appeals from felony convictions in which the punishment is less than 10 years’ confinement. In such cases “the trial court may”:
(5) “deny bail and commit the defendant to custody if there then exists good cause to believe that the defendant would not appear when his conviction became final or is likely to commit another offense while on bail;” 10
(6) “permit the defendant to remain at large on the existing bail,”11 the amount of which the court may increase or decrease,12
(7) “if not then on bail, admit him to reasonable bail until his conviction becomes final.”13
As for the defendant whom the trial court finds in the sixth or seventh class, “The court may impose reasonable conditions on bail pending the finality of his conviction. On a finding by the court on a preponderance of the evidence of a violation of a condition, the court may revoke *401the bail.”14 The appellant in this ease is in the sixth class.
Judicial discretion to deny bail pending appeal, or to make it conditional, arrived less than 15 years ago. Before 1907, a defendant who was convicted of a felony was not eligible for bail. The statutes required, “Where the defendant appeals in any case of felony, he shall be committed to jail until the decision of the [appellate court].”15
In 1907 a statute authorized bail pending appeal in a felony case, but it gave the trial court discretion only as to amount. Any defendant who was convicted of a felony, and whose punishment did not exceed fifteen years’ confinement, was entitled to bail.16 In its 1965 reenactment, the statute read, “Any defendant who is convicted of a misdemeanor, or who is convicted of a felony and whose punishment is assessed at a fine or confinement not to exceed fifteen years or both, shall be entitled to bail under the rules set forth in this Chapter pending disposition of his motion for new trial, if any, and pending disposition of his appeal, if any, and until his conviction becomes final.”17
In 1977, the trial court’s discretion was enlarged. The controlling statute, article 44.04 of the Code of Criminal Procedure, was amended to remove the concept of a felon’s entitlement to bail pending appeal.18 The trial court was given discretion, even when the punishment was less than 15 years, to deny bail or to impose reasonable conditions on bail.19
In 1999 another amendment restricted the eligibility for bail pending appeal by lowering the ceiling to cases in which the punishment was less than 10 years and by eliminating the “3g” offenses.20
At the same time, magistrates were given authority to impose reasonable conditions on pre-trial bail. “To secure a defendant’s attendance at trial, a magistrate may impose any reasonable condition of bond related to the safety of a victim of the alleged offense or to the safety of the community.”21
It will be noted that the statutes treat conditions on pre-trial bond differently from conditions on bail pending appeal. A condition of pre-trial bond must meet three standards: Not only must it be “reasonable,” but it also must be to “secure a defendant’s attendance at trial,” and also *402be related to the safety of the alleged victim or the community. The latter two standards were not imposed on the trial court’s conditions of bail pending appeal, which must only be “reasonable.”
We have not considered the significance of the legislature’s decision to impose three standards on conditions on pre-trial bonds while leaving only one standard for conditions on bail pending appeal.
III.
Our previous decisions have assumed that the standard the legislature chose for conditions on pre-trial bonds in 1999 also applied to conditions on bail pending appeal under the 1977 statute. The difference between the statutes now demonstrates that the standards may be different, at least as they are expressed by the legislature. Judicial decisions also show a difference between bail before trial and bail pending appeal.
The first appeal to question the validity of a condition on bail pending appeal, which was authorized by the 1977 statute, was Estrada v. State 594 S.W.2d 445 (Tex.Cr.App.1980). Estrada appealed from conditions on his bail pending appeal that required him to leave weekly urine samples to be tested and the results reported to the court, to seek drug counseling if his urine-test results indicated the need, to report to a probation officer, to remain in the jurisdiction of the court except by express permission, and to obtain suitable employment. The question was whether the conditions were reasonable and did not constitute an abuse of discretion. The appeal was decided by a panel of three judges of this Court. The panel’s judgment affirmed the trial court’s decision, upholding eight conditions of bail pending appeal of a conviction for possession of heroin: to commit no crime, to report monthly to the probation officer, to report changes of address or job status, to remain within the county, to work, to submit urine samples to a clinic, to permit the clinic to report urinalysis results to the court, and to attend counseling at the clinic’s recommendation. Judge Douglas announced the judgment of the panel and filed an opinion in which no other judge joined; the other two members of the panel concurred only in the result.
In Judge Douglas’s opinion, the 1977 statute was constitutional for this reason:
The fountainhead of constitutionality of bail conditions is that they be “based upon standards relevant to the purpose of assuring the presence of (the) defendant.” Stack v. Boyle, 342 U.S. 1, 72 S.Ct. 1, 96 L.Ed. 3 (1951). Such conditions may not impinge unreasonably upon rights guaranteed by the Constitution. [Footnote 2:] See, e. g., United States ex rel. Means v. Solem, 440 F.Supp. 544 (U.S.DistCt. for Dist. of S.D.,1977), where the court found a provision that Means could not participate in the activities of the American Indian Movement to be an unreasonable impingement upon his first amendment rights. [End footnote]
We hold that the term “reasonable” in relation to conditions authorized by Article 44.04(c) encompasses these tests, and that the power of the court to impose reasonable conditions on appeal bonds is not repugnant to the Constitution of the United States or of Texas.22
In interpreting “reasonable” to incorporate the Stack test that a condition be relevant to assuring the presence of the defendant for trial, Judge Douglas’s opinion did not take note of fundamental differences between bail before trial and bail *403after conviction. “Once the defendant’s trial is completed and he has been convicted, his situation with respect to his release, even if he plans to take an appeal, changes significantly.”23
Stack involved the amount of bail before trial on federal charges. The Supreme Court said:
From the passage of the Judiciary Act of 1789 to the present Federal Rules of Criminal Procedure, federal law has unequivocally provided that a person arrested for a non-capital offense shall be admitted to bail. This traditional right to freedom before conviction permits the unhampered preparation of a defense, and serves to prevent the infliction of punishment prior to conviction. Unless this right to bail before trial is preserved, the presumption of innocence, secured only after centuries of struggle, would lose its meaning.
The right to release before trial is conditioned upon the accused’s giving adequate assurance that he will stand trial and submit to sentence if found guilty. Like the ancient practice of securing the oaths of responsible persons to stand as sureties for the accused, the modern practice of requiring a bail bond or the deposit of a sum of money subject to forfeiture serves as additional assurance of the presence of an accused. Bail set at a figure higher than an amount reasonably calculated to fulfill this purpose is “excessive” under the Eighth Amendment.24
How many of the Court’s considerations in Stack were relevant to Estrada’s bail pending appeal?
• Stack was “a person arrested for a non-capital offense.” Estrada was a person convicted of an offense.
• A right to bail pending appeal from a conviction is not recognized in the Constitution of the United States25 or in the Texas Constitution.26 Stack’s case was controlled by federal law that has always provided that all persons arrested for a non-capital offense shall be admitted to bail. Texas statutes have never provided that all convicted felons shall be admitted to bail pending appeal.
• Stack enjoyed “the traditional right to freedom before conviction [which] permits the unhampered preparation of a defense, and serves to prevent the infliction of punishment prior to conviction.” Freedom after conviction is not traditional, and it is not necessary for the preparation of a defense.27 Rather than serving to prevent the infliction of punishment before conviction, bail pending appeal delays the infliction of punishment and rehabilitation after conviction.
• For Stack, the right to bail before trial was essential to preserving the meaning of the presumption of innocence. That presumption no longer applied to Estrada, a convicted felon.28
*404• Stack’s bail served as additional assurance of his presence in court for trial. After appeal, no appearance in court takes place in the vast majority of cases. Rather the clerk of the district court fulfills a ministerial duty to issue a capias for the arrest of the defendant, which is executed by the sheriffs placing the defendant in jail.29 Bail pending appeal is only an additional assurance that the appellant will be available to be arrested.
None of the considerations that underlay the Supreme Court’s decision in Stack being applicable to Estrada’s case, they give no support to Judge Douglas’s conclusion that a Texas court’s condition on bail pending appeal is “reasonable” only if it meets federal standards for bail before conviction.
Six years later, this Court elaborated on Estrada by saying:
Thus, determining the “reasonableness” of a bail condition must be done in light of its purpose, to assure the presence of the defendant. In each individual case where conditions are imposed, those conditions must strike a balance between society’s interest in assuring that the defendant will appear if and when his conviction becomes final and the defendant’s interest in remaining free pending appeal.30
Once again we ignored the difference between a defendant’s interest in remaining free before trial, which is a right recognized in the Texas Constitution31 and which furthers important constitutional objectives, and a convicted defendant’s interest in remaining free during appeal, which is not a constitutional right32 and which is not necessary after conviction.
Thereafter, this Court and the courts of appeals have employed the Estrada stan*405dard in deciding whether other conditions of bail pending appeal were reasonable.33
In the light of the 1999 statute and our further consideration of the interests that the statutes protect, the “standards relevant to the purpose of assuring the presence of the defendant” that Judge Douglas incorporated in his Estrada opinion for construing “reasonable conditions on bail pending [appeal]” in Article 44.02(c) cannot be regarded as correct.34 Estrada and its progeny35 provide valuable guidance for evaluating conditions on pre-trial bonds, but they are misleading as to conditions on bail pending appeal.
IV.
We must inquire afresh, is it a reasonable condition on bail pending appeal that the appellant not operate a motor vehicle? Or, as the Court of Appeals suggested, is the district court authorized to keep the appellant off the roads only by keeping him in jail without bail?
Except for capital cases and a few categories of felonies,36 every person accused of a felony has the right to pre-trial bail. As we have said above, bail before trial permits the unhampered preparation of a defense, and serves to prevent the infliction of punishment prior to conviction. These interests are of great weight in every case. Yet in setting bail for a pre*406sumptively innocent suspect, a magistrate must consider the nature and circumstances of the alleged offense37 and the safety of the alleged victim and the community,38 and the magistrate may impose a reasonable condition related to their safety.39
After conviction the right to bail is afforded in all misdemeanor cases, and, subject to conditions, in felony cases in which the punishment does not exceed 10 years’ confinement. The only interest that is furthered by a defendant’s right to remain free during appeal is the interest in protecting the defendant from an erroneous judgment. The issue is not whether this class of appellants should be denied the right to remain free on appeal; it is only, while they are free on appeal, what conditions on their freedom are reasonable?
Against the interest of such appellants must be balanced the interest of society in enforcing the penal laws. Chief among these, in the cases of those who have been convicted of felonies, is “to insure the public safety through: (A) the deterrent influence of the penalties ... provided; (B) the rehabilitation of those convicted of violations ...; and (C) such punishment as may be necessary to prevent likely recurrence of criminal behavior.”40 If the public policy of this state permits a magistrate to consider the public safety in imposing a condition on pre-trial bail, surely it must be reasonable for a condition on bail pending appeal to have the purpose of protecting the public safety.
In a case in which a defendant has been convicted of killing an individual by driving his commercial vehicle with criminal negligence, and in which he was involved in another injury-accident while driving a commercial vehicle before trial, a condition that he not operate a motor vehicle while free on bail pending appeal has the purpose of protecting the public safety. It is not unreasonable because of that purpose, and it is not unreasonable on any other ground.
The judgment of the Fourteenth Court of Appeals is reversed.

. "Bond pending appeal
"(a) Pending the determination of any motion for new trial or the appeal from any misdemeanor conviction, the defendant is entitled to be released on reasonable bail, and if a defendant charged with a misdemeanor is on bail, is convicted, and appeals that conviction, his bond is not discharged until his conviction is final or in the case of an appeal to a court where a trial de novo is held, he files an appeal bond as required by this code for appeal from the conviction.
"(b) The defendant may not be released on bail pending the appeal from any felony conviction where the punishment equals or exceeds 10 years confinement or where the defendant has been convicted of an offense listed under Section 3g(a)(l), Article 42.12, but shall immediately be placed in custody and the bail discharged.
“(c) Pending the appeal from any felony conviction other than a conviction described in Subsection (b) of this section, the trial court may deny bail and commit the defendant to custody if there then exists good cause to believe that the defendant would not appear when his conviction became final or is likely to commit another offense while on bail, permit the defendant to remain at large on the existing bail, or, if not then on bail, admit him to reasonable bail until his conviction becomes final. The court may impose reasonable conditions on bail pending the finality of his conviction. On a finding by the court on a preponderance of the evidence of a violation of a condition, the court may revoke the bail.
"(d) After conviction, either pending determination of any motion for new trial or pending final determination of the appeal, the court in which trial was had may increase or decrease the amount of bail, as it deems proper, either upon its own motion or the motion of the State or of the defendant.
"(e) Any bail entered into after conviction and the sureties on the bail must be approved by the court where trial was had. Bail is sufficient if it substantially meets the requirements of this code and may be entered into and given at any term of court.
"(f) In no event shall the defendant and the sureties on his bond be released from their *400liability on such bond or bonds until the defendant is placed in the custody of the sheriff.
"(g) The right of appeal to the Court of Appeals of this state is expressly accorded the defendant for a review of any judgment or order made hereunder, and said appeal shall be given preference by the appellate court.
"(h) If a conviction is reversed by a decision of a Court of Appeals, the defendant, if in custody, is entitled to release on reasonable bail, regardless of the length of term of imprisonment, pending final determination of an appeal by the state or the defendant on a motion for discretionary review. If the defendant requests bail before a petition for discretionary review has been filed, the Court of Appeals shall determine the amount of bail. If the defendant requests bail after a petition for discretionary review has been filed, the Court of Criminal Appeals shall determine the amount of bail. The sureties on the bail must be approved by the court where the trial was had.

"When the trial court clerk receives the mandate, the appellate court’s judgment must be enforced as follows: ...
"(b) Judgment of Affirmance; Defendant Not in Custody.
"(1) Capias to Be Issued. If the judgment contains a sentence of confinement or imprisonment that has not been suspended, the trial court must promptly issue a capias for the defendant's arrest so that the court’s sentence can be executed.
"(2) Contents of Capias. The capias may issue to any county of this state and must be executed and returned as in felony cases, except that no bail may be taken. The capias must:
"(A) recite the fact of conviction;
"(B) set forth the offense and the court’s judgment and sentence;

"(B) the rehabilitation of those convicted of violations of this code; and
"(C) such punishment as may be necessaiy to prevent likely recurrence of criminal behavior;
"(2) by definition and grading of offenses to give fair warning of what is prohibited and of the consequences of violation;
"(3) to prescribe penalties that are proportionate to the seriousness of offenses and that permit recognition of differences in rehabilitation possibilities among individual offenders;
"(4) to safeguard conduct that is without guilt from condemnation as criminal;
"(5) to guide and limit the exercise of official discretion in law enforcement to prevent arbitrary or oppressive treatment of persons suspected, accused, or convicted of offenses; and
"(6) to define the scope of state interest in law enforcement against specific offenses and to systematize the exercise of state criminal jurisdiction." Tex. Penal Code § 1.02.
