a minor Top 40 hit, peaking at No. 40 on the Billboard Hot 100 in the United States. To promote the new album, Clark was added as the opening act for Reba McEntire and Brooks & Dunn 1998 tour. Fearless, Clark's fourth studio album, was issued in September 2000. During the album's production, Clark started writing more personal songs with a new team of co-writers and hired a new producer to deliver a set of songs with a more acoustic feel than that of her previous work. The album's first single, "A Little Gasoline", was a late addition to the album because Mercury executives felt Clark needed to balance her new material with something that had a more familiar feel to it. The song reached the top ten in Canada, however, only reaching No. 13 in the United States. On May 2, 2001, Clark was pulled over by police for speeding in Nashville. The officer, who pulled Clark over, had suspected that she had consumed alcohol and asked her to do sobriety test, after which Clark refused and was charged with a DUI and implied consent. Clark later apologized for the incident through a statement that was issued to press by her publicist. In August, Clark pleaded guilty to a charge of reckless driving and was fined $350 plus court costs, placed on six months' supervised probation and ordered to take an alcohol education course. 2002–2004: Pain to Kill and Greatest Hits 1994-2004 After a management change in December 2001, Clark began work on her fifth studio album, Pain to Kill.

The song, written by Kelley Lovelace and Lee Thomas Miller, was initially intended to be recorded by Sara Evans, who passed on it. When released as a single the song became Clark's highest-charting single in the United States since 1998's "You're Easy on the Eyes" and is to date Clark's highest appearance on the U.S. Billboard Hot 100, peaking at No. 27. The album marked the first time Clark had worked with producer Byron Gallimore, who produced the first half of the album. The other half was produced by Clark's longtime producer Keith Stegall, who was brought in when Gallimore became unavailable. In early 2004, Clark was approached by Playboy magazine to pose—clothed—for the cover of the magazine's
