The teenager died in a head-on crash with a car on August last year near to RAF Croughton inNorthamptonshire.
The driver of the car, Anne Sacoolas, claimed diplomatic immunity and returned to the US, where she has been sinceHarrydied.
Now, police say they are aware of footage of a separate incident which shows a car on the wrong side of the road involved in a near-miss close to the base.
They also revealed that officers were involved in a crash with a car on the wrong side of the road in October, but said no one was injured.
Sky News understands both vehicles were diplomatic cars registered to RAF Croughton.
Diplomatic immunity has not been applied for in the case of the incident involving a collision with a police vehicle.
Officers have called for talks with the base commander at RAF Croughton to discuss the safety of the roads around it.
Chief Constable Nick Adderley said: “Northamptonshire Police is aware of an incident yesterday evening on a road between Mixbury and Fulwell House where a vehicle driving on the wrong side of the road was involved in a near-miss with another vehicle.
“We are working closely with Thames Valley Police who are the lead agency in regards to this incident and will do all we can to support their investigation.
“In the meantime, I do not underestimate how much of a concerning incident this was and how much worse it could have been, especially considering the circumstances in which – year-old Harry Dunn tragically died.
“This is also compoun ded by the fact that yesterday, myself and police, fire and crime commissioner Stephen Mold were made aware of another incident in Northampton in which a police vehicle was struck in early October by a vehicle also driving on the wrong side of the road. Thankfully there were no injuries.
