Free gas will be available through temporary fuel trucks that are being deployed across the five boroughs and Long Island, according to the New York Post. But not so fast.

The state Division of Military and Naval Affairs issued an advisory asking that the public keep away from the pumps until emergency vehicles could fill up, according to the Wall Street Journal.

Once the first responders fill up: “The 5,000 gallon trucks will be deployed throughout the morning and there are an additional 150,000 gallons of fuel available to restock the trucks throughout the day. There is a 10 gallon limit per vehicle. Cars can fill up directly off of the truck.”

Here is a list of the fueling stations in Brooklyn and Queens.

Brooklyn Armory
