How do you say "Turn left / right" in Spanish?

The phrase "Gira a la izquierda / derecha" literally translates to "Turn left / right" in English. This phrase is commonly used for giving directions, making it the correct choice when asking someone how to instruct another to turn in a specific direction.

The verb "girar" means "to turn," and when combined with "a la izquierda" (to the left) and "a la derecha" (to the right), it clearly articulates turning movements in both directions. This direct command is easily understood in the context of navigation or driving.

The other options relate to different phrases without addressing the concept of turning. One mentions life jackets which is unrelated, while another warns to be careful, and the last advises caution too, but they do not pertain to directional instructions. Thus, the choice that directly corresponds to the question about turning directions is logical and correct.
