Boris Johnson says he will raise the issue of the driving standards of US personnel with secretary of state Mike Pompeo, in the wake of the death of Harry Dunn.
Speaking at a conference in Berlin, the PM said: "We're certainly raising all those issues - about the driving habits of US personnel at the base - and we're continuing to work for justice for Harry Dunn and for his family".
The teenager died in a head-on crash with a car on 27 August last year near to RAF Croughton in Northamptonshire.
The driver of the car, Anne Sacoolas, claimed diplomatic immunity and returned to the US, where she has been since Harry died.
Yesterday, police revealed that diplomatic cars were driven on the wrong side of the road in two separate incidents near the RAF base where the teenager was killed last year.
Johnson told reporters he will discuss the crash which killed Mr Dunn, and the two further incidents, with secretary Pompeo while they are both attending a summit in Germany.
The PM has previously described the chances of the US handing over Anne Sacoolas, the woman who was driving the car which hit Mr Dunn, as "very low".
Sacoolas, 42, the wife of a US intelligence official, claimed diplomatic immunity and returned to the US, where she has been since Harry died.
She is believed to have been driving on the wrong side of the road.
But the US has called the request "highly inappropriate".
