SHERIFF, CLARK COUNTY, Nevada, Appellant,
v.
Mark Allen LEVINSON, Respondent.
No. 11850.
Supreme Court of Nevada.
June 14, 1979.
*233 Richard H. Bryan, Atty. Gen., Carson City, Robert J. Miller, Dist. Atty., and Steven J. Parsons, Deputy Dist. Atty., Las Vegas, for appellant.
Goodman, Oshins, Brown & Singer, Chtd., and William B. Terry, Las Vegas, for respondent.

OPINION
PER CURIAM:
At the conclusion of a preliminary examination respondent was held to answer on two counts of involuntary manslaughter (NRS 200.070). Thereafter, respondent filed a pretrial petition for a writ of habeas corpus, contending his restraint was illegal because the information failed to adequately state the offenses charged. The district court found the information to be insufficient, and ordered the writ granted. From the order of the district court, this appeal has been perfected.
In reviewing the sufficiency of the information before us, we are mindful of established principles regarding the function and requisites of the information. The information is the first pleading by the state in a criminal action (see NRS 173.015) and must contain "a plain, concise and definite written statement of the essential facts constituting the offense charged." NRS 173.075(1). In the information, the prosecution is required to make a definite statement of facts constituting the offense in order to adequately notify the accused of the charges and to prevent the prosecution from circumventing the notice requirement by changing theories of the case. See Simpson v. District Court, 88 Nev. 654, 503 P.2d 1225 (1972). In accord with these principles, we have held that an information which alleges the commission of the offense solely in the conclusory language of the statute is insufficient. See Earlywine v. Sheriff, 94 Nev. 100, 575 P.2d 599 (1978).
In the instant case, both counts of the information are identical in all pertinent respects.[1] Each count provides a definite date and location for the commission of the offense, states that the offense occurred *234 while respondent was engaged in a lawful act (driving a car), and alleges that the offense occurred because respondent was driving in an unlawful manner (in excess of 100 miles per hour). We are not concerned with whether the information could have been more artfully drafted, but only whether as a practical matter, the information provides adequate notice to the accused. See Laney v. State, 86 Nev. 173, 466 P.2d 666 (1970).
In our opinion, the information in this case contains a sufficiently clear statement of the facts surrounding the alleged commission of the offense to apprise the respondent of the charges against him. Accordingly, the order of the district court granting the petition for a writ of habeas corpus is reversed.
