Police are waiting on the results of blood and urine tests before considering charges against a Sydney bus driver accused of injuring three people when he ploughed his vehicle into several homes in the city's northwest.
The 61-year-old allegedly returned a positive blood-alcohol reading in a roadside test soon after the North Ryde smash.
His bus was travelling along Epping Road about midday on Saturday when it left the road, mounted the kerb and smashed into two homes, police say.
The driver, who was not injured in the crash, was taken to Royal North Shore hospital for mandatory testing.
Two women in one of the houses suffered minor injuries and were taken to hospital for observation, while a man in another house was also hurt.
There were no passengers on the bus at the time of the crash.
