Tournez à gauche is a standard instruction from French satellite navigation systems, the equivalent of turn left in English. Short voice prompts like this were widely shared as isolated clips on soundboards because they are instantly recognisable even to non French speakers who have driven in France. Online, creators separated the phrase from real driving and began using it as a punchline for confusion, bad directions, and travel fails. Its continued popularity comes from that official tone clashing with silly situations.
