Understanding Auto Insurance Code 484 in Police Reports

What Is Auto Insurance Code 484?

Auto Insurance Code 484 appears in the incident description section of a police report. It indicates that the driver was charged with a traffic violation, specifically a "failure to yield" or "rear‑end collision" that resulted in a loss of control. The code is used by law enforcement to flag incidents that may involve a claimable injury or property damage. It is not a legal penalty but a shorthand for the type of accident and the probable insurance implication.

Why Police Use Code 484

Police departments use a standardized code system to streamline incident logging. Code 484 is part of the National Incident Reporting System (NIRS) and is mapped to the National Highway Traffic Safety Administration's (NHTSA) classification of "rear‑end collisions." The code helps dispatchers, investigators, and insurance adjusters quickly identify the nature of the accident without reading the entire narrative. It also assists in data aggregation for traffic safety studies.

Impact on Your Auto Insurance Claim

When an insurance company receives a police report with Code 484, it signals that the claim involves a rear‑end collision. Adjusters will look for:

• Vehicle damage reports
• Witness statements
• Liability indications

Because rear‑end collisions often involve a single point of contact, many policies cover the damage under the "collision coverage" component. If you have a deductible, that amount will apply. If the other driver is at fault and uninsured, you may seek coverage under uninsured/underinsured motorist protection.

Common Misconceptions

Some policyholders think Code 484 automatically means the other driver is at fault. That's not always true; the code merely records the type of collision. Fault is determined after a full investigation, which may involve traffic cameras, skid marks, and driver statements. In some jurisdictions, the code is retained even if the final fault determination is "unknown."

What to Do If You See Code 484

1. Review the full report. Look for the narrative section where the officer explains the circumstances.

2. Check your policy. Verify whether you have collision coverage and whether you're covered for uninsured motorist claims.

3. File a claim promptly. Most insurers require notification within 30 days of the incident.

4. Keep documentation. Photographs of damage, medical bills, and repair estimates support your claim.

5. Consult a claims specialist. If the police report is vague, a professional can help interpret the code's implications.

When Code 484 Is Not Enough

Some claims involve multiple codes. For example, a collision that also includes a "speeding" violation might have both Code 484 and Code 301. In such cases, insurers review all codes to assess liability and potential penalties. If you suspect a code was misapplied, contact the reporting officer's department for clarification.

Statistical Context

Key Takeaways

Code 484 is a standardized marker for rear‑end collisions in police reports. It guides insurers in processing claims but does not determine fault on its own. By reviewing the full report, understanding your policy, and acting quickly, you can navigate the claims process more effectively.
