American Olympic swimmer Michael Phelps admitted to police he had a beer an hour and 15 minutes before he was involved in a car accident last Thursday in Maryland, reports Perez Hilton. Police, however, have ruled out alcohol as the cause of the collision, saying Phelps showed “no signsof alcohol impairment.” They deemed sobriety tests unnecessary at the scene of the accident.

The other driver, Amanda E. Virkus, caused the accident by running a red light.

Phelps and the two passengers in his Cadillac Escalade walked away from the crash uninjured.

The swimmer has been issued a citation by police, as he was driving with an invalid license at the time of the incident. He will not be required to pay a fine, but must appear in court to explain why he does not have a valid driver’s license.
