The emergency services in various countries use systems of response codes to categorize their responses to reported events. One of the best known is the Code 3 Response, which is used in several countries, particularly the United States, to describe a mode of response for an emergency vehicle responding to a call. It is commonly used to mean "use lights and siren."
Although the exact origin of Code 3 is not clearly known, its use has spread across the United States and into parts of Canada.
Code 3 was the title to a 1950s television police procedural intended to compete with Dragnet.
The Greaseman used the term in one of his songs, "I Love To Go Code 3".
The most commonly used response codes are:
Watching me fall
Into the flames
Of a broken soul tonight
No stone overturned
This graveyard of mine
Allows me no peace
[Chorus]
Sleep as day dies
Sleepwalk with the dead
Wander aimlessly through the night
Love and regret
Course through my veins
As I slowly fade away
Please let me sleep
Just one last night
Before I must wake
[Chorus]
And I walk with these ghosts
And I walk with these ghosts
And I walk with these ghosts...
[Chorus]
Sleep as night falls
Sleepwalk with the dead
Hope keeps me alive
