That's what Vince Neil hit with his Pantera. The drummer from another band was in the car with Vince and was killed in the crash.
Pretty certain signal 30 was used in Driver ED in the early 60’s also.I took driver ed with Amos Neyhart’s protege in the late 1960s at State College High. Signal 30 was removed from the curriculum the year before. Over three decades later, I dug it up, and used it for my orientation class when I was safety director for a major trucking company. Made a serious impression all those years later.
That one looks like it was parked in a driveway and the parking brake didn't hold and it rolled away. A reminder to always leave your car in gear when parked or even put a chock behind a tire!
