Anne Sacoolas has refused to answer any questions after being sentenced for causing the death of teenage motorcyclist Harry Dunn.
In exclusive footage from Sky News, the former US spy was seen with her lawyers in Washington, DC, where she appeared by video link for her sentencing, but declined to answer questions.
She has been sentenced to eight months imprisonment suspended for 12 months for causing the death of Harry by careless driving.
Sacoolas, 45, was driving her Volvo on the wrong side of the B4031 in Northamptonshire, a two-lane road with a 40mph limit, when she hit the 19-year-old, who was riding in the opposite direction.
She pleaded guilty.
Sky's James Matthews approached Sacoolas after her sentencing and asked her: "What words do you have for Harry Dunn's family?" to which she replied: "Have a nice day."
Sacoolas and her team then try to prevent the correspondent from joining them in their lift, while ignoring his questions.
