A three-year-old girl was killed after she was struck by a tablet during a car accident.
The child was using the tablet device during the car journey when her mother collided with the back of a school bus on Monday.
The impact of the crash caused the tablet to fly into her face.
She was sitting in an Isofix-anchored child seat during he time of the crash but this did not prevent the device striking her.
Police said that the unsecured tablet appeared to have caused severe head injuries.
The mother and one student on the school bus were treated for minor injuries.
It is a tragedy which road safety organisations have described as highly unusual.
The incident took place on Monday in Vilanova de Arousa, which is a small town in the north-west of Spain.
“This is a tragic accident, which will send a shudder down the spine of every parent who lets their child use a tablet or smartphone as entertainment on any car journey,” the RAC’s road safety expert Pete Williams told the BBC.
“We have not heard of any similar incidents but it is important to realise that in a high-speed accident any hard object which is not strapped down inside a vehicle has the potential to become a lethal projectile.”
The Highway Code states that “heavy or sharp objects” must be “safely secured” to prevent injury.
It is becoming increasingly more common for parents to use smartphones or tablets to keep their children entertained on the roads.
There are devices that will secure these devices to the back on the seat in front to prevent them moving around in the case of an accident.
“There are products that can be used to strap devices to the seat on front, which parents can use to reduce the risk that unsecured objects can pose,” said Edmund King, the Automobile Association’s president.
“However, we are not aware of any similar cases and this does appear to be a freak incident.”
The Royal Society for the Prevention of Accidents said parents should not rush to ban electronic devices from vehicles since noisy, bored children posed risks of their own.
“This is clearly a very tragic but very rare incident,” said Nick Lloyd, Rospa’s road safety manager.
“Any unsecured object within a vehicle has the potential to become a projectile and injure someone in a crash, and parents should be aware of this, but at the same time it may be more dangerous to have an unentertained child in the back of a car on a long journey, distracting the driver.”
