OPINION
delivered the opinion for a unanimous Court.
Appellant, Scott Alan Kirsch, was convicted of his second driving while intoxicated (DWI) offense in violation of Texas Penal Code § 49.04(a). 1 Tex. Pen.Code § 49.04(a). In his petition for discretionary review, appellant argues, in two issues, that the court of appeals erred by affirming the trial court’s charge to the jury, which included a definition of the statutorily undefined term “operate” as it is used in the DWI statute. We conclude that the trial court erred in defining that term and reverse the judgment of the court of appeals.
I. Background
On the night of the offense, Julie Richards was driving home from work on State Highway Loop 281 in Longview, Texas, when she encountered appellant straddling a motorcycle with his hands on the handle bars stopped in the middle of the road at an intersection. Ms. Richards testified that, after a few moments, he began slowly tilting to one side and “just leaned over until he fell completely on the ground, one leg under the motorcycle, one over it still straddling it.” She pulled up beside him and asked if he needed assistance, which he declined. But as she drove away, she saw in her rearview mirror that he made no attempt to get up. She called the Harrison County Sheriffs Department and reported the incident.
Deputy Kevin Johnson testified that he promptly responded to the call. When he arrived, he observed appellant sitting on top of his motorcycle attempting to “kick-start” it, which appellant ceased when Deputy Johnson approached him. Deputy *648 Johnson testified that appellant’s speech was slurred and that he had difficulty following directions and balancing. Deputy Bill Turner soon arrived and conducted an “intoxication investigation.” Based on that investigation, Deputy Turner concluded that appellant was intoxicated and placed him under arrest.
Appellant was charged by information with DWI. At trial, the trial court, in its written charge to the jury, defined “operate” as “to exert personal effort to cause the vehicle to function.” Defense counsel objected to this instruction, arguing that
on the first page, the last paragraph should be eliminated from [the charge], as to the words, “The term operate.” There is no definition of the word “operate” in the Penal Code and these are made up by the prosecutor himself, by his own admission, and put in here.
The trial court explained that the prosecutor had submitted “a case with that language in there.” 2 Defense counsel responded that the ease law to which the State referred did not pertain to jury instructions. Overruling the objection, the trial court submitted the charge to the jury. The jury convicted appellant and assessed his punishment.
On direct appeal, appellant complained that the trial court erred by defining “operate” in the jury charge, arguing that it is “a common term” and that provision of a definition constituted a comment on the weight of the evidence.

Kirsch v. State,
No. 06-10-00071-CR,
We granted review in this case to determine whether the court of appeals erred in holding that the trial court acted within its discretion in instructing the jury on a definition of the term “operate” as used in the DWI statute.
II. Analysis
In two grounds for review, appellant inquires whether, in the guilt-innocence charge in a DWI case, it is necessary to define the term “operate” and asks if the court of appeals erred in approving a definition of that term. He contends that the definition was an improper comment on the weight of the evidence.
A. Preservation of Error
*649
The court of appeals concluded that, although “the trial court was not obligated to give a definition of ‘operate,’ it did not exceed its ‘broad discretion’ by providing the correct definition, because ‘the definition of “operate” was directly at issue.’ ”
Kirsch,
Furthermore, contrary to the court of appeals’s conclusion that appellant did not adequately brief this issue in his direct appeal, appellant’s first issue in his direct-appeal brief stated, “The definition is a comment on the weight of the State’s evidence,” and he concluded that the instruction “emphasized personal effort without regard to the merely preparatory attempts to start the motorcycle.” Although he relied primarily on evidentiary-sufficiency cases discussing definitions of “operate” in support of his argument, his brief was sufficient to advance his improper-comment complaint. 5 Similarly, in his petition for discretionary review, he argues that a trial court “cannot create a charge that by its terms comments on the conduct at issue.” In his brief, he adds that “the non-statutory instruction” constituted “a prohibited comment on the weight of the evidence,” citing applicable authority. Because the court of appeals erred in declining to address his issue, and because he properly raises it in this Court, we must decide whether the trial court’s instruction improperly commented on the weight of the evidence.
B. Error Analysis: Trial Court Erred in Defining “Operate” in Jury Charge
1. “Operate” is a Statutorily Undefined, Common Term
The Texas Penal Code provides that a person commits the offense of driv
*650
ing while intoxicated when the person “is intoxicated while operating a motor vehicle in a public place.” Tex. Pen.Code § 49.04(a). The Code does not define the term “operating.”
See id.; see also Denton,
The State argues that the term “operate” “no longer has the simple, common, narrow definition accepted by lay persons, but is broader than the normal understanding of the general population.” It cites several “lay” definitions of the term and argues that “[c]ommon parlance says that operate means to, ‘make it go,’ ” whereas the legal definition “is tantamount to an ‘attempt to operate.’ ” However, case law does not support this contention, as many Texas juries have rendered guilty verdicts even when the evidence showed that the operator did not successfully make the vehicle “go.”
See, e.g., Denton,
The court of appeals correctly noted that this Court has concluded that a person “operates” a vehicle when “the totality of the circumstances [ ] demonstrate that the defendant took action to affect the functioning of his vehicle in a manner that
*651
would enable the vehicle’s use.”
Kirsch,
2. Instruction on Definition was Comment on Weight of Evidence
The trial court is required to give the jury a written charge “setting forth the law applicable to the case; not expressing any opinion as to the weight of the evidence, not summing up the testimony, discussing the facts or using any argument in his charge calculated to arouse the sympathy or excite the passions of the jury.” Tex.Code Crim. Proc. art. 36.14. We have generally held that, if a jury-charge instruction “is not derived from the [penal] code, it is not ‘applicable law’ ” under art. 36.14. Walters v. State, 247 S.W.3d 204, 214 (Tex.Crim.App.2007). With only limited exceptions, 10 the trial court may not include an instruction that focuses the jury’s attention on a specific type of evidence that may support a finding of an element of an offense. Id. at 212. Juries are free to “consider and evaluate the evidence in whatever way they consider it relevant to the statutory offenses,” and “special, non-statutory instructions, even when they relate to statutory offenses or defenses, generally have no place in the jury charge.” Id. at 211.
An instruction, albeit facially neutral and legally accurate, may nevertheless constitute an improper comment on the weight of the evidence.
See, e.g., Brown v. State,
Here, in defining the term “operate” as “to exert personal effort to cause the vehicle to function,” the trial court selected one definition of a statutorily undefined, common term that the jury could have selected in assessing the evidence and instructed the jury that they “must be governed by” that definition.
See Abdnor,
Furthermore, as appellant noted in his direct-appeal brief, the definition emphasizes evidence tending to show “personal effort” toward causing the vehicle to function over evidence that would tend to show “merely preparatory attempts to start the motorcycle,” which the jury could have reasonably decided did not constitute “operating.”
See Dornbusch,
Whether appellant was operating his motorcycle was a question of fact to be resolved by the jury.

III. Conclusion
We reverse the judgment of the court of appeals and remand to that court to determine whether appellant suffered harm as a result of the erroneous instruction.
See Abdnor,
Notes
. Under that section, "[a] person commits an offense if the person is intoxicated while operating a motor vehicle in a public place.” Tex. Pen.Code § 49.04(a).
. It is not apparent from the record to which case the trial court referred.
. Appellant also complained that evidence was legally and factually insufficient to show that he was "operating” a vehicle, which the court of appeals overruled. Appellant does not challenge the sufficiency of the evidence in his petition for discretionary review.
. We express no opinion as to whether appellant properly preserved his complaint that the instruction constituted an improper comment on the weight of the evidence.
. We note that cases discussing jury-charge issues in this context frequently also discuss sufficiency issues. In fact, in deciding the jury-charge issue in this case, the court of appeals cited primarily sufficiency cases, as well as an improper-comment case.
