The phrase "did a U-turn" is often used to describe a sudden change in direction. However, this term may not always be the best fit for the context. Some alternative phrases that convey the same meaning include "made a 180-degree turn," "turned around," "reversed course," "made a sharp turn," "swung back," and "turned on a dime." In some cases, you may also be able to use more descriptive language to explain the change in direction, such as "veered off to the right," "jerked the car to the left," or "pivoted on the spot." By being creative with your word choices, you can add nuance and flair to your writing and communication.
