Answer:
Metaphor
Step-by-step explanation:
A metaphor is quote : "a figure of speech in which a word or phrase is applied to an object or action to which it is not literally applicable." In this case, we talk about being on a right track not literally, but its just a way to say that "you're close to the answer". Getting run over is just like that too. You are not going to get literally run over, its just a statement that implies that you won't get any farther. Hope this helps. Please ignore the literally at the end, I didn't find a way to remove it :).
