What should officers do before deciding to arrest a driver for DUI?

Before deciding to arrest a driver for DUI, it is essential for officers to gather evidence and observations. This process involves collecting information that can substantiate their suspicions of impaired driving. Key aspects include observing the driver's behavior, noting any signs of intoxication, such as slurred speech, the smell of alcohol, or poor coordination. Officers may also assess the driver's performance on field sobriety tests if conducted.

Gathering this evidence is crucial because it provides a factual basis for the arrest, ensuring that it is justified and can hold up in court. Proper documentation of observed behavior and physical evidence also helps in establishing the case against the driver, protecting the officer and the legal process from potential challenges.

Other options may support the process but do not directly address the necessary pre-arrest steps as effectively as gathering evidence does. For instance, waiting for backup may ensure officer safety, but it does not contribute to the justification for the arrest itself. Asking the driver for a statement can provide additional insights but may not be reliable, especially if the driver is impaired. Contacting a supervisor might be necessary in specific situations, but the primary responsibility lies in collecting evidence and making observations before proceeding with an arrest.
