White House Emergency Response Vehicles
There are three groups that would respond to an emergency in the White House. Each has it’s own territory.
Looking at the White House from the North Grounds the division breaks down as follows:
The Street in front o the White House is protected by the WASHINGTON DC METROPOLITAN POLICE.
The fence around the White House and grounds inside are protected by the UNIFORMED DIVISION of the US SECRET SERVICE.
White House security vehicles have the Presidential Seal on the door as well as a Secret Service Seal.
Emergency Response Vehicles at GW
Both US SECRET SERVICE and WASHINGTON DC METROPOLITAN POLICE VEHICLES would be seen here.
In general the Secret Service is supposed to alert the Metropolitan Police if they are moving but if there’s an emergency they will likely just go and not wait to coordinate the effort.
