Straight on is a term used in directions to indicate a path or course that follows a straight line, without any curves or turns. However, there are a variety of synonyms that can be used to indicate the same thing. These include continuing ahead, proceeding forward, advancing straight, moving straight, following a direct path, walking ahead without deviation, maintaining direction, staying the course, and keeping on the same route. These synonyms all convey the same message but vary in their tone and level of formality. Whether using straight on or these alternatives, it is important to ensure instructions are clear and direct.
