Yonkers police have been doing some fall cleaning – by clearing unregistered vehicles off the streets, that is.

The department put together a video to NSYNC's "Bye Bye Bye" to show what they've been up to.

The department says its No. 1 complaint is about reckless, unregistered mopeds, scooters, dirt bikes and motorcycles.

Police say that on Thursday they impounded 30 of them in an eight-hour intensive search. The past month, the department impounded over 100 of them.

Police say they're always on the lookout.
