A 34-year-old man has been taken to hospital after falling out of a car window while throwing beer bottles at the vehicle behind.
Police said the woman driver, who was on a learners' permit, was driving down Atherton Range Road towards the north Queensland town of Atherton around 4.20pm (AEST) on Sunday when she yelled at the front seat passenger.
He was asleep and the woman needed some directions, police said.
But the man thought she was upset with the car driver behind them and began throwing beer bottles at the car.
While he was leaning out the window throwing the bottles, he fell onto the road and then rolled into a drainage ditch.
He suffered a possible broken ankle and bruising and was taken to the Cairns Base Hospital for treatment.
