What should officers do if they suspect a driver is under the influence of alcohol?

The appropriate response when officers suspect a driver is under the influence of alcohol is to request a breathalyzer test. This action is critical as it provides a quantifiable measurement of the driver's blood alcohol concentration (BAC). If the BAC exceeds the legal limit, it gives law enforcement the evidence needed to initiate appropriate legal action, which is essential in maintaining public safety.

When officers suspect impairment, it is their responsibility to investigate thoroughly. The breathalyzer test serves as a standardized method to assess whether the driver is legally intoxicated. This process aligns with established protocols for handling suspected DUI situations, ensuring that officers act within the law and uphold their duty to protect citizens on the road.

Other choices presented do not align with the best practices for handling suspected DUI cases. For example, simply releasing a suspected impaired driver with a warning fails to address the potential danger they pose to themselves and others. Allowing someone who appears fine to leave without testing does not account for the fact that alcohol impairment is not always visible. Following them until they park delays necessary intervention without mitigating the risk of potential harm on the roads.
