When radio codes slice through police radio traffic, 1059 means assault with a deadly weapon, but 1055 has its own specific meaning for officers on the street. Understanding these numeric designations helps civilians interpret scanner chatter and recognize how departments structure emergency responses.
Below you can scan a quick reference that maps key 10-series codes, including 1055, alongside related situations and response priorities to show how each number fits into everyday policing.
| Code | Officer Meaning | Typical Situation | Priority Level |
|---|---|---|---|
| 1055 | Driver fleeing, pursuit in progress | Vehicle refuses to stop, high-speed follow | High |
| 1042 | Silent run, no lights or siren | Routine patrol with minimal visibility | Low to medium |
| 1070 | Property damage or burglary in progress | Forcible entry, shattered windows or doors | Medium to high | sh
What 1055 Specifically Signals on the Radio
Definition and Core Purpose
Code 1055 indicates that a driver is fleeing and officers are actively pursuing a vehicle. This designation triggers heightened radio traffic, coordination with nearby units, and often air support in larger jurisdictions. The number is not random; it is embedded in regional code books that standardize how patrol cars report danger and urgency.
How Dispatch Uses This Code
When dispatch announces 1055, they are broadcasting that a tactical response is escalating. Officers in adjacent sectors may be asked to block intersections, monitor highways, or prepare emergency vehicle intercept tactics. The code helps channel resources to the exact segment of roadway where the chase is unfolding, reducing confusion and increasing safety.
Relationship to Other Pursuit Codes
Agencies often nest 1055 within a family of pursuit codes that describe stages of a chase. Earlier codes might signal the initial traffic stop, while later numbers indicate crashes, suspect detention, or termination of the pursuit. Mapping these related codes clarifies how an ordinary stop can evolve into a multi-unit operation requiring air cover and emergency medical standby.
Context Behind Modern Police Radio Codes
Origins of the 10-Series
The 10-code system emerged from mid-twentieth century radio limitations, when departments needed short numeric bursts to convey complex situations quickly. Over time, variations developed across states and cities, but the logic remains similar: compact numbers replace lengthy descriptions so officers can maintain focus on the street while listening to the radio.
Training and Public Awareness
Most new officers memorize 1055 during field training when they first ride with a partner and hear the code crackle over the scanner. Agencies often publish code sheets for public affairs units and community outreach, yet many of the higher-numbered designations remain internal. Public familiarity with a handful of critical codes, such as 1055, can improve situational awareness without compromising operational security.
Community Impact and Transparency
How These Codes Affect Neighborhoods
When 1055 echoes over a scanner, neighbors may hear sirens weaving through side streets as units converge. Understanding that this code refers to a fleeing vehicle helps residents anticipate road closures, temporary detours, and increased patrol presence. Transparent communication from agencies about what these codes mean can ease community concerns during high-speed events.
Balancing Speed and Safety
Pursuit protocols tied to codes like 1055 increasingly emphasize de-escalation, aerial coordination, and public notification. Departments weigh the severity of the original offense against the risk of high-speed driving, and many now require supervisors to authorize continued chase. These policies aim to protect bystanders, officers, and suspects while still addressing violent flight.

FAQ
Reader questions
Does 1055 always mean a high-speed chase with lights and sirens?
Yes, 1055 typically indicates an active vehicle pursuit where the driver is refusing to stop, prompting lights, sirens, and coordinated response tactics.
Can 1055 be used for pursuits on foot or by bicycle?
It is primarily designated for vehicular pursuits; foot or bicycle chases usually fall under different pursuit or containment codes.
Will I hear 1055 on a public scanner in my city?
In many regions, 1055 is transmitted on conventional police radio frequencies, although some agencies encrypt certain tactical traffic, limiting scanner clarity.
What should I do if I hear 1055 near my neighborhood?
Seek shelter indoors, avoid roadways, and follow any instructions from local media or authorities until officers declare the scene safe.
