Aissatou Diallo has pleaded not guilty to 38 charges of dangerous driving, including three counts of dangerous driving causing death, stemming from the fatal crash on Jan. 11, 2019. Court has heard that from the moment the bus strayed onto the Transitway shoulder to the moment it struck the shelter overhang, Diallo never applied the brakes.
