The song reached No. 55 on the UK Singles Chart despite considerable airplay. Guitarist Mike Herbage later described the song as "an aggressive, trance and beat driven track" but expressed surprise at the fact that it charted at all, calling its placing "probably higher than it had any right to, really". Vocalist Vaughn Toulouse was a bit more positive, saying, "I think 'I Want' and 'Going Left Right' are ... really representative of the band". In a later interview, Herbage admitted that "Going Left Right" and third single "I Want" were both "very strong tracks" and added, "we worked so hard on ''"
Retrospective reviews for the song were universally positive. Paolo Hewitt of Melody Maker said that it and "I Want" were "far superior" to "Is Vic There?", Mimi von Tussle of Sputnikmusic called it "always a crowd-pleaser" and "sublime", while Leonard's Lair said that it "matched 'Is Vic There?' for swagger and military precision". Dave Thompson of AllMusic said that it "stands among the finest songs of the entire post-punk early '80s".
