NASCAR has suspended Truck Series driver Jack C. Smith for violating the substance abuse policy.
The suspension is indefinite. NASCAR announced the discipline Tuesday.
Smith made six starts this season with a best finish of 11th at Atlanta. His last race was at Texas, where he crashed and finished 26th.
