Tiger Woods crashed his car near his home in Florida in late March. He has previously denied allegations that he was under the influence of drugs.
Neither Woods nor the driver of the other vehicle sustained any injuries.
Woods submitted a breath test after the accident, which was negative, but refused to submit to a urine test.
The golf legend has had problems with back and knee injuries for several years, has been involved in four car accidents and has become addicted to painkillers.
