NASCAR truck series driver Ray Ciccarelli -- who has 0 career wins in the series -- is QUITTING over the organization's new Confederate flag ban ... saying it's all a bunch of "political BS."
The 50-year-old -- who joined NASCAR's Gander RV & Outdoors Truck Series in 2017 -- teed off on the ban on his Facebook page Wednesday night ... announcing his plan to leave over the matter.
"Well its been a fun ride and dream come true but if this is the direction NASCAR is headed we will not participate after 2020 season is over," Ciccarelli's post read.
