A Code 3 Response in the United States is used to describe a mode of response for an emergency vehicle responding to a call. It is commonly used to mean "use lights and siren".

In some agencies,[which?] Code 3 is also called a Hot Response. Code 1 is also called a Cold Response. In some individual departments they have their own response codes. Code 2 being lights and siren and code 3 would mean the same as code 2 but without lights and siren. An example of this would if a patrol car is close and does not want to alert anyone of their arriving.

Some slang may be used, such as "Running Hot", or "Running Cold".

Some departments may use the terms "upgrade" and "downgrade" as well. If a unit is responding to a call without lights or sirens (code 1), and the unit later needs to turn on lights and sirens (code 3), the term upgrade may be used. The term downgrade may be used in the opposite situation.

A similar variation is to "reduce" or "increase code." For example, if there is a code 3 response to a situation, but the first units on scene have sufficient control of the situation, they may announce over the radio that responding units may "reduce code." In this example, to "reduce code" would mean to continue responding, but at code 2, rather than discontinue altogether; to alert units to discontinue altogether—e.g., because the suspect is in custody or there are already enough police officers, also known as “e-r’s” on scene—they would likely say they are "code 4."
