Mail truck !!! The reason being it is part of the Federal Gov. I would definitely say that the ambulance and fire truck have the right of way, if they are going to an emergency or transporting a person to the hospital.
Very extensive discussion with citations and references at:

An emergency vehicle has the right of way. There may be different kinds of emergency vehicles, but the U.S. mail vehicle is in no way an emergency vehicle...
Yes, over to the right side of the road when it is safe to do so.
all traffic, in either direction, must slow down, pull to the right of the road, and stop until the emergency vehicle passes

Overtaken? Hence the vehicle is approaching rapidly from behind. You are to slow down and move to the right side of the road in the U.S. as long as it is safe to do so. If there is a shoulder, you are required to pull on to the shoulder and stop your vehicle as long as it is safe to do so) until the emergency vehicle passes you. Basically, you are to yield the right of way to emergency vehicles.
In the USA, slow down and move to the right side of the road as soon as it is safe to do so. On a 2-lane road, move to the shoulder. Allow the emergency vehicle to proceed.

You need to get out of their way, pulling over to the right, off of the side of the road (if possible) and stopping.
move to a lane not adjacent to emergency vehicle and pass with caution
No! The most important thing is to make room for it to safely pass you. Do this by moving to the right or left, depending on the rules of the road in the country concerned, stopping if approaching an intersection, or if otherwise needed for safety. If the emergency vehicle is in a lane to your left and is unimpeded there is no reason to stop or move to the right unless other traffic might get in its way. If the emergency vehicle is stopped on the shoulder, you should safely move to the left or right and SLOW DOWN until you have passed! Stopping where you are can block traffic, preventing the progress of the emergency vehicle.
Turn on your flashers to help the emergency vehicle. If the emergency vehicle is moving and has a siren running, pull over to the side of the road.
If your country normally drives on the right side of the road then you should pull over to the right as far as your safely can and come to a complete stop If your country normally drives on the left hand side of the road (England, Japan, Australia etc.) then you pull over as far as you safely can to the left and come to a complete stop.
