Porn star Ron Jeremy's car has been impounded by police after he was caught allegedly driving the vehicle without a California licence.

The 61 year old was pulled over in Hollywood on Wednesday (03Sep14) after police suspected him of drunk driving, according to Tmz.com.

Jeremy was administered a Breathalyzer test and police determined he had not been drinking, but they discovered he was only licensed to drive in New York, despite living in California for several years.

Jeremy's car was impounded and he was forced to take a taxi cab home.
