Martin Asolo-Ogugua, 23, drove the bus into Ada Bicakcim, a young Turkish and British national, on August 3, 2024 at 9.30am.
While driving down Watling Street, near the junction with Halcot Avenue, the driver fell asleep at the wheel after taking cannabis the previous night.
He mounted the opposite pavement at the exact moment Ada was riding her bike across it with her family.
The bus also crashed into her five-year-old brother.
Ada’s family managed to jump to safety, but she was taken to hospital where she died two days later on August 5.
He was arrested on suspicion of causing serious injury through dangerous driving and drug-driving.
Officers built enough evidence to charge him on February 13 thus years, with causing death by dangerous driving while under influence of drugs as well as driving while over the drug limit.
He pleaded guilty to both offences at Woolwich Crown Court on April 22.
Asolo-Ogugua, of Banfield Road in Southwark, was also disqualified from driving for seven years.
‘My family have crumbled’
Ada’s father, Bora, said: “The images of that horrific moment remain seared into my mind. That scene replays endlessly, a constant reminder of the day my world fractured beyond repair.
“This tragedy happened on my watch, a father’s ultimate failure. My world has been turned upside down, and with it, the foundations of my family have crumbled.
“My darling Ada. Our thanks are not enough to show our gratitude for you. We will honour your name with acts of magnitude. You will never be forgotten.
“We will make this story one of love and thanks that we owe everybody.
“Your presence, and passing, will leave a mark in this country and we will fight to make drug driving a part of its history.”
“His actions have robbed a young girl of her entire life. Our thoughts remain with Ada’s family and friends as they try to come to terms with their unimaginable loss
“I hope his sentence today can help to bring some closure for Ada’s family and highlight the devastating consequences of drug driving.”
