WHEN WILL PEOPLE LEARN!!! U CAN’T BEAT A BUS DRIVER!!!!!

If last month’s epic bus driver fight taught you nothing, let this new video serve as a final lesson — DO NOT MESS WITH YOUR BUS DRIVER … because she will beat the crap out of you.

The new video was shot yesterday on board a Baltimore bus — showing a female bus operator unleashing a ferocious beatdown on a female high school student.

According to the person who posted the clip on YouTube, the fight started because the student was playing her music too loud — and the bus driver hit FIRST.
