In the context of police codes, 1013 means "Advise weather and road conditions". This code is used by police officers to communicate information about the weather and road conditions to other officers or emergency responders. However, it is important to note that police codes can vary by region and department, so the meaning of a particular code may differ depending on where it is used.

It is worth mentioning that in a mental healthcare environment, a 1013 form is used to initiate transportation to an "emergency receiving facility" and is completed by an authorized licensed clinician. This is a different use of the term "1013" and is not related to police codes.
