Wondering if a road grader carelessly backed into TBLE's server.

There was an MBE question about a lady walking down the street and getting hit by a road grader (or something like that). I believe it was a Torts question. I'm a non-traditional student/Bar exam taker (didn't decide to go to law school until 48 yo, graduated and took Bar this July at 51 yo--just found out I passed btw!!), so I had lived enough life to know what road grader was. I felt really bad for many younger test takers after reading some posts right after the MBE portion. They had no idea what a road grader was and I just thought it was really an unfair question to have an essential piece of the analysis relying on an object that is not necessarily common knowledge and wasn't defined within the question.
