In 2011, the Oklahoma Department of Transportation's Trash-OFF became Oklahoma's signature event in the Great American Cleanup™, the nation's largest community improvement program, held annually from March 1 to May 31.

Each spring, the ODOT Trash-OFF brings together thousands of volunteers who are dedicated to making Oklahoma a cleaner, greener and more beautiful - thus making it the single largest ONE-day cleanup event in the State of Oklahoma.

ODOT Trash-OFF participants are eligible to receive trash bags, volunteer badges and other promotional items made available through the Great American Cleanup™ national sponsors, Keep America Beautiful and Keep Oklahoma Beautiful.
