CHARLOTTE, N.C. (AP) - NASCAR has asked a federal judge to order
a mental and physical examination on suspended driver Jeremy Mayfield to determine if he has a substance-abuse problem.
NASCAR also wants to know if Mayfield suffers from attention-deficit hyperactivity disorder, as he claims.
Monday's filing includes three affidavits and a deposition from four different people who claim to have witnessed Mayfield using methamphetamines multiple times since 1999.
Mayfield has been suspended for failing a random drug test collected May 1. NASCAR has said he twice tested positive for methamphetamines, but Mayfield has denied using the illegal drug.
