The US diplomat’s wife who fled the UK after being accused of killing a teenage motorcyclist in a crash had been fined before for her driving, according to a report Tuesday.

Anne Sacoolas, 42, is at the heart of a diplomatic tussle between the US and the UK after declaring immunity over the death of 19-year-old Harry Dunn in a wrong-way, head-on crash in late August.

Now it has emerged that Sacoolas — whose husband, Jonathan Sacoolas, works for US intelligence — was previously fined over her driving while living in Virginia, according to a report.

The mother of three was charged with failure to “pay full time and attention” in Fairfax in 2006, according to the Times of London.

She did not dispute the charge and paid the penalty — currently set at $97 — in full to avoid going to court, the paper said, citing court documents.

On Aug. 27, Sacoolas had her 12-year-old son in her Volvo SUV when she drove on the wrong side of a Northamptonshire road and fatally struck the teenage motorcyclist, authorities allege.

She took a breathalyzer test and initially cooperated, before British police learned in mid-September that she had left the country.

“We were given assurances by the American authorities that she would cooperate fully … that she would not be leaving the community, and would not be leaving the country. The next minute we found out she and her family had left,” Nick Adderley, the chief constable of Northamptonshire, told the Times.

“We are not saying she is guilty in this situation but she has a duty — and I’m saying a moral obligation — to assist and make sure we can get closure or at least answers for Harry’s family,” he said.

There has been no sign of Sacoolas at the home in Vienna, Virginia, where she lived for three years before moving to Britain, according to the Sun.

Neighbors told the paper that they saw a moving truck last month and a sign reading, “We are renters and not who you are looking for.”
