NASCAR president will keep test details private

INDIANAPOLIS (AP) -- NASCAR President Mike Helton says he intends to keep details about positive drug tests private.

Speaking shortly before Nationwide Series drivers began practice on Indianapolis' historic 2.5-mile oval, Helton said he sees no reason to change the organization's long-standing non-disclosure policy.

Questions about transparency have arisen since both urine samples from A.J. Allmendinger tested positive for what business manager Tara Ragan says was an amphetamine. Allmendinger has been suspended indefinitely and insists he does not know what caused the positive tests. NASCAR has provided no details about the positive tests.

Citing federal privacy provisions, Helton says NASCAR will continue to let those who test positive decide whether to disclose additional information.
