The A199 in East Lothian remains closed while police 'thoroughly' search the area.
A gun has been fired in a disturbance involving a "number" of vehicles on the A199.
The incident happened at around 1.35pm on Monday near Strawberry Corner Garden Centre in East Lothian.
The road has been closed while police conduct a "thorough" search of the area.
Two cars have already been seized and police are appealing to drivers who may have dash-cam footage that will help with their enquiries.
Superintendent Angus MacInnes, from Lothians and Sottish Borders Division, said: "While we are still working to establish the exact nature of the incident on Monday, we believe this to be an isolated matter involving a group of people all known to one another.
"We do not believe there to be a risk to the general public.
"In particular, we would like to speak to motorists who were on the A199 on Monday afternoon and may have dash-cam footage of what happened.
"I want to stress that incidents of this nature are incredibly rare and we have a dedicated team carrying out an extensive investigation to bring those responsible to justice."
