Street Racing Sign?

I forget where I've seen it before and I've looked all over, but can't seem to find it.

It's a yellow sign that looks like a pedestrian crossing sign. But it has 2 cars lined up and in the middle is a stick figure(like on other road signs) who has his hands out like he is flagging the race.

I want to get a sign with this on it or shirt or whatever I can find it on.........even a pic at least.

Thanks for any help ya'll.

Nevermind guys and gals. Someone on another webpage found it for me.
