A 22-year-old driver smashed into four parked scooters near Taichung's Fengjia shopping area early Thursday, and while nobody was hurt, he tested positive for ketamine.

• The car lost control on Fuxing Road around 3 a.m. and plowed into the parked scooters, leaving a mess but no injuries.
• A breath test showed zero alcohol, so police ran a saliva drug screen, which came back positive for ketamine.
• No drugs were found in the car, but he was sent to prosecutors on a drug-driving public endangerment charge and his car was impounded.
• Police stress the saliva screen is only preliminary — a urine test and officer observation records will decide the case.

Outlook: The urine test results will determine whether the drug-driving charge sticks.
