Two children have been seriously injured after being hit by a car on Bribie Island, north of Brisbane.
The children and a woman in her 30s, who was also injured, have all been taken to hospital.
They were struck by the vehicle on Goodwin Drive at Bongaree about 11:49am.
A female toddler with multiple abrasions has been rushed to the Queensland Children's Hospital in a serious condition and were met by a "high acuity response team", which is tasked to save the lives of seriously injured patients.
A male infant has also been taken to the Queensland Children's Hospital with a head injury in a serious but stable condition.
The woman who suffered multiple abrasions has been transported to the Royal Brisbane and Women's Hospital.
A 95-year-old driver was uninjured and was assisting police.
He was taken to the Caboolture Hospital as a precaution.
Children hit while crossing the road
Goodwin Drive Family Medical Centre practice manager Angela De-Gaetano said she, two doctors and a nurse from the business attended the injured trio.
"There was a six-month-old baby, a four-year-old girl and the mother. They were hit by a ute when they were trying to cross the road," Ms De-Gaetano said.
"We were mostly reassuring the mother, but the doctors were assessing the six-month-old baby.
"We were a bit uncertain about how bad he was. He was breathing, very sort of limp but he was breathing and had his eyes open.
"He wasn't very responsive, but he was a lot better by the time the ambulance had transported him."
Ms De-Gaetano said the mother was holding the baby in a carrier on her chest at the time of the incident.
Intersection prone to accidents
It comes after the Commonwealth government last year gave $472,000 to boost road safety at the Goodwin Drive intersection under its black spot program.
The funding provided traffic lights for a pedestrian crossing in an effort to prevent the high number of accidents and near misses that were reported in the area.
Ms De-Gaetano said a zebra crossing had recently been changed into a set of traffic lights.
"There was a witness there that said he saw it and thought that the lights didn't work correctly," she said.
"It's distressing but they've all left alive and hopefully they're all OK."
Queensland Ambulance Service officer in charge Jarred Thorne said paramedics treated four people at the scene.
"We had eight units respond, three acute ambulances, CCT [Critical Care Paramedic], HARU [High Acuity Response Unit], and the operational supervisor," he said.
