Police are to question the father of a seven-year-old girl who died when the quad bike she was given for Christmas was involved in a head-on collision.
The girl was taken to hospital where she died from her injuries
Elizabeth Cooke, from Blackmore, near Brentwood, Essex, was taken to hospital where she died from her injuries.
Pauline Bowers, head of Blackmore Primary School, said: "Lizzie was a lively and popular girl who will be greatly missed by all."
A 28-year-old woman, from the Brentwood area has been arrested over the crash.
She had been driving a Range Rover, and was questioned on suspicion of causing death by careless driving while unfit through drink or drugs before being bailed until New Year's Eve.
The crash occurred in Fingrith Hall Lane, just outside the village of Blackmore, on Boxing Day.
The girl and her 10-year-old brother were both riding their new bikes behind their father's car when the accident occurred.
Ms Bowers, her head teacher said: "Our thoughts and love are with the family at this sad time.
"The school will be taking steps to help staff and pupils cope with this tragic loss to our community."
Anyone who witnessed the crash between the Shark quad bike and the Range Rover, which occurred at about 1900 GMT, is asked to contact Essex Police.
Some manufacturers make smaller quad bikes with automatic transmissions for children. It is illegal to ride such machines on public roads without a licence and insurance.
Some junior quad bikes are capable of speeds of up to 40mph (64km/h).
A spokesman for road safety charity Brake said: "Even with permission to use the machines on private land, children should not be put in control of them - the sheer power and speed of them is dangerous wherever they are used."
