A seven-year-old girl died after her quad bike was involved in a head-on collision with a Range Rover in Essex.
A woman, 28, who was driving the Range Rover, was arrested on suspicion of causing death by careless driving while unfit through drink or drugs.
Anyone who witnessed the crash between the red Shark quad bike and the red 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."
