Normally in NASCAR, when the caution flag comes out, it's because of something that has gone wrong with one of or multiple cars on the track. Once things get taken care of on the track, the cars are then allowed to get up to full speed again.

However, in this instance, the caution flag was out because of some idiot fan.

A spectator was trying to climb up the crash fence in turn four at Richmond International Raceway in Richmond, Va., during the Sprint Cup Federated Auto Parts 400 race on Saturday.

Thanks to some pictures and an Instagram video, you're able to see what this idiot fan was doing before security got him down.
