You turn.
"You go straight ahead and turn left at the stop sign!" is an English equivalent of the French phrase Vous allez tout droit et vous tournez à gauche au stop! Context makes clear whether vous translates as one "you" or two or more "you all" in English. The pronunciation will be "voo-za-ley too dwa ey voo toor-ney a go-sho stop" in Alsatian French.
Tournez a gauche means turn left in the imperative or 2nd person (formal/plural) form. e.g. when giving directions
If that is the phonetic spelling it probably is tournez which means turn.
to turn is "tourner" in French. "tournez à gauche, tournez à droite"
