What should you do when you are driving and see an Emergency Vehicle approaching?

You should yield to the right.  When the Emergency Vehicle is approaching even if it is from the opposite way, yield to the right.  The Emergency Vehicle will pass you on the left side of the road even when you are on the opposite side of the road.  If you yield to the right, you will leave ample space for the vehicle to have plenty of driving space to get by safely.  In a two way highway, still yield to the right, the Emergency Vehicle will know where you are planning to go.  If there is one Emergency Vehicle that passes you, look and make sure there is not another Emergency Vehicle behind them, stay where you are.  Many times there are Sheriffs Department, Rescue and Fire vehicles behind each other so make sure there is not anyone behind the first Emergency Vehicle.  Give them plenty of space to drive by because they are traveling at a high rate of speed to get where they are going to and they may be driving a large truck that needs more room on the highway then a regular car or truck.
