What should an officer do if a driver appears to be under the influence?

When an officer suspects that a driver is under the influence, the appropriate action is to conduct field sobriety tests. This process allows the officer to assess the driver's physical and cognitive abilities in a controlled manner, providing evidence to support the suspicion of impairment due to alcohol or drugs. Field sobriety tests typically include tasks such as balance tests, coordination tests, and assessments of the driver’s ability to follow instructions.

This step is crucial for ensuring that the officer has enough information to make informed decisions about whether to arrest the driver or take further legal actions. Properly conducted tests can substantiate a DUI charge if necessary, leading to proper legal proceedings. While issuing a citation or letting the driver go with a warning might seem like reasonable options, they do not address the seriousness of the situation or the potential danger posed by an impaired driver on the road. Additionally, calling for a tow truck would not adequately resolve the immediate concern of public safety and responsibility regarding the suspected impaired driving.
