You should slow down, yield , and let the emergency vehicle clear the intersection before you go.

What you should do step by step

  1. Look ahead and confirm the flashing blue and red lights are an emergency vehicle entering or about to enter the intersection.
  1. Even though the intersection is clear, ease off the accelerator and be prepared to stop before entering it.
  1. If the emergency vehicle is coming through the intersection (from any direction), stop and stay out of the intersection so it has full right of way.
  1. Only proceed into and through the intersection once the emergency vehicle (and any others following it) has passed and it is clearly safe to move again.

In most driver-licence-style questions written like this, the single best answer is: Stop (or prepare to stop) and let the emergency vehicle pass before entering the intersection.

Quick Scoop:
When you see flashing blue and red lights as you’re about to enter a clear intersection, the law and safe-driving practice both say: your green light or “right of way” no longer matters—yield completely to the emergency vehicle, wait, then go when it’s gone and the way is safe.
