The incident, in which her red moped collided with a Volvo XC90 happened on the westbound carriageway near the Ashley Heath roundabout.
16-year-old Jade from Ringwood, was pronounced dead at the scene.
Her mother, Sharon, said: “Jade was a wonderful daughter and a loving sister to Corrina, William, Rachal, Danni and Tommy.
“She was studying at college to become a hairdresser and was a very active member of the Young Firefighters Association in Ringwood, where she really enjoyed spending her time.
“Jade was a lovely young lady with a large group of friends – words cannot describe how much we all miss her.
“I know that nothing will bring Jade back or reduce our suffering but we have been warmed by the overwhelming support that we have received from the public – people who didn’t even know Jade.
“The whole family is also extremely grateful to the media for their help with the investigation and the support from the people and businesses in Ringwood.”
