How to Read Police Report Codes NJ

Understanding New Jersey Police Report Codes for Road Conditions

Road surface codes may indicate conditions such as dry, wet, snow-covered, icy, unknown, or other surfaces. The lighting category includes daylight, dark, dawn, dusk, and other options.
Review Vehicle and Driver Information
After analyzing the details about the crash and the environment, you can review the sections that provide information about the vehicles and drivers. Pay close attention to the vehicle or driver identification, direction, use, and circumstances.
For instance, when there are two cars mentioned in a report, one can compare the information on Vehicle 1 and Vehicle 2 to identify inconsistencies. If one of the cars was going straight while the other one turned, this information can be useful in conjunction with the police report.
NJ Accident Report vs. Self-Reported Crash Form

When learning how to read a police accident report, avoid interpreting any single code on its own. You should always review an entire section and how it applies to the whole report. For example, looking at a collision code can help you identify what type of crash occurred, but the diagrams and narrative are also essential for understanding the details.
