What is the purpose of a police report after a DUI arrest?

The purpose of a police report after a DUI arrest is to document details of the stop, evidence of impairment, and the arrest process. This report serves as a critical legal document that captures key information such as the time and location of the stop, the behavior and physical condition of the driver, observations made by the officer, field sobriety test results, and any breath or blood test results. By thoroughly documenting these elements, the report creates a factual record that can be used in court to support the prosecution's case and can also be referenced during legal proceedings to ensure an accurate representation of the events that transpired. This comprehensive documentation is vital for establishing whether the law enforcement procedures were followed and to substantiate the evidence of impairment leading to the arrest.
