"Highway Don't Care" is a song performed by American country music artist Tim McGraw and features American singer-songwriter Taylor Swift on vocals, as well as Keith Urban on guitar. It was released in March 2013 as the third single from McGraw's first album for Big Machine Records, Two Lanes of Freedom (2013). The song was written by Mark Irwin, Josh Kear and Brad and Brett Warren. McGraw and Swift recorded their parts separately.

The song is a mid-tempo ballad where the male narrator is separated from his lover who is driving. Throughout the verses, he tells her what he "bets" she is feeling, when a song comes on her radio (its part sung by Swift) containing the lines "I can't live without you, baby." He also says that the highway she's driving on doesn't care if she's alone or if she's going home, but he does. The song is in D major with a main chord pattern of D-B_m7-G_sus2-A.Keith Urban plays lead guitar on it.

Thom Jurek of Allmusic, in his review of the album, wrote that "the hook is irresistible and McGraw's vocal, paired with the young singer's, is a perfect match." Chuck Dauphin of Roughstock also reviewed the song favorably, saying that "this song flows well, with winning performances from two of the format’s top vocalists." Billy Dukes of Taste of Country gave the song five stars saying that the track is arguably "one of the best collaborations of the decade — maybe even ever. Each artist brings his or her best effort to the song from McGraw’s Two Lanes of Freedom album. 'Highway Don’t Care’ feels like a special moment from the very first listen, and only becomes more cathartic with time." Jeff Benjamin of Fuse said the track has "major crossover potential." The single has also been a great commercial success. It has sold 1,743,000 copies in the US as of November 2013.
