A 31-year-old woman and her six-year-old son are fighting for their lives in hospital following a horrific smash on the A90 north of Dundee on Monday night.
The woman’s two other young children, aged three years and six months, were also in the car but unhurt in the collision between a Vauxhall Corsa and a Mercedes on the northbound carriageway at the Tealing junction.
The mother was taken by helicopter to Ninewells Hospital following the accident, which occurred at rush hour just after 5pm.
Firefighters had to use cutting gear to free the 31-year-old from the wreckage of her Vauxhall.
Police said on Monday that she the mum and her six-year-old son had both sustained serious injuries in the collision.
A 24-year-old student nurse from Forfar was among the first on the scene.
He had been travelling back home by bus when the vehicle stopped at the accident scene.
He said: “I saw the black Mercedes in the central reservation.
“As the bus slowed down I noticed the woman in the other car. She looked as though she was unconscious.
“The little boy looked unconscious too but when I got down there he was crying.
“I went down because I’ve trained in basic life support because of my training. I just wanted to make sure everybody was stable and breathing.”
The trainee nurse, who has a one-year-old son, added: “There was another nurse there and a doctor and we helped to get everyone out the car but we couldn’t get the woman because she was trapped.
“There was a baby in the front seat and a little girl but they were unharmed.
“I was just thinking what if it was my son.”
The road was closed for two hours while emergency services attended the incident, causing length tailbacks in both directions.
Police Scotland Road Policing Unit officers are still investigating the circumstances of the incident, and are appealing for any witnesses to contact call 101, or speak to any police officer.
The accident has prompted fresh calls for safety measures to be intrroduced on the road.
Transport Scotland is to install average speed cameras between Dundee and Stonehaven but Tealing Community Council has said more must be done to reduce the number of accidents.
Chairwoman Sandra Burke, said: “We need much more than that to make the road safer for residents, drivers and pedestrians. This has been an accident black-spot for over 20 years, including several heartbreaking fatalities.
“We want the Scottish Government to urgently consider installing proper acceleration and deceleration lanes at the junctions, a 50mph limit between Fintry and the Glamis turn-off plus the installation of a pedestrian fly over.
“Community and elected representatives are meeting with BEAR Scotland in Tealing on July 5 to start scoping out the safety review.
“We welcome the meeting, in fact it can’t come quickly enough. Much more must be done to make this stretch of the A90 safer for all users.”
