11-25 means traffic hazard in the California Highway Patrol's aural brevity card. CHP adds "specify type," so the short code is not the complete description. Chowchilla, Cotati and San Jose also list traffic hazard; Sebastopol uses "Vehicle / Traffic Hazard." These are meanings in five named California documents, not a nationwide rule.

The shared phrase does not establish identical handling across agencies. Cotati explicitly describes its radio list as partial and adapted to local use. Keep the agency attached to the definition, even when several lists agree on the short wording.
What can count as a traffic hazard?
Chowchilla's Communications Training Manual goes beyond the code list. Its Traffic Hazard section, printed page 90 (PDF page 93), gives these examples:
- A vehicle stalled in a traffic lane.
- An object lying in the roadway.
- Material on the road surface, such as concrete, sand or oil.
- Flooding, including water from rain or prolonged sprinkler use.
- Traffic signals that are not working properly.
These are Chowchilla's examples, not a requirement to classify every similar event the same way elsewhere. They explain why 11-25 need not involve a vehicle collision or an abandoned car: the reported problem can be an obstruction, a surface condition or a signal fault.
11-25 versus 11-24 and 11-26
The neighboring numbers describe different things in the CHP and Chowchilla lists:
- 11-24: abandoned vehicle in both documents.
- 11-25: traffic hazard, with CHP asking for the type to be specified.
- 11-26: "Disabled vehicle, occupied" in CHP; "Disabled Motorist" in Chowchilla.
Those distinctions do not make the real-world situations mutually exclusive. Chowchilla includes a stalled vehicle in traffic lanes among its hazard examples while separately listing a disabled-motorist code. A vehicle can be disabled and obstruct traffic. The brief entries do not supply a universal rule for choosing between labels.
Do not drop CHP's "occupied" qualification when describing its 11-26 entry. Also, the 11-code comparison records a different 11-26 meaning in Atherton and Belmont: abandoned bicycle. Those two lists use 11-23 for a vehicle or traffic hazard. Neighboring numbers are not a dependable national sequence.
Does 11-25 mean an accident or injury?
Not by itself. CHP separately lists crash codes, including 11-79 for a traffic crash with an ambulance rolling and 11-80 for a major-injury crash. A traffic-hazard label alone establishes neither a collision nor an injury. 11-41 is the separate ambulance entry in the CHP card.
For example, an object reported in a lane fits one of Chowchilla's hazard examples without establishing that a vehicle struck it. That is an illustration of the published description, not a real dispatch transcript or a claim about the eventual outcome.
1125: radio spelling versus CAD context
1125, 11 25 and 11/25 are search variants here. Cotati supplies a specific document connection: it prints hyphenated 11-25 in Radio Codes and unhyphenated 1125 as Traffic Hazard in its event-type and field-event tables. Field events are officer-initiated entries. That supports Cotati's usage, not every agency's bare number.
The San Diego County Sheriff manual is a different source. Its 11-series entries on printed pages 66-67 do not include 1125. It prints 1124: Abandoned Vehicle for a vehicle parked on a contract-city public street for more than 72 hours, without suspicious qualities or license-plate wants, and excludes Santee. That is not a radio traffic-hazard definition. See the Sheriff event-code guide for its separate context.
Does 11-25 specify the response?
The five 11-25 entries name the problem, not a response level or a guaranteed arrival time. They do not establish that a tow truck or ambulance has been requested. CHP has a separate 11-85 tow-truck entry. Keep any accompanying location, hazard description and response information rather than inferring them from 11-25 alone.
