What should a police officer do if they suspect a driver may be under the influence based on their behavior?

When a police officer suspects that a driver may be under the influence based on their behavior, conducting a field sobriety test is an appropriate and justified action. This test is designed to evaluate the driver's physical and cognitive abilities, which can indicate whether they are fit to drive. The officer benefits from observing the driver's performance on these tests, allowing them to gather evidence to support further actions, such as an arrest or additional testing for blood alcohol content.

Field sobriety tests are standardized and provide a systematic approach to assessing impairment. They include a series of physical coordination tasks and can aid in determining the level of intoxication without needing immediate arrest. This process also offers the driver the opportunity to demonstrate their sobriety, which is important for procedural fairness.

Effective law enforcement requires officers to balance public safety with an individual's rights. Conducting a field sobriety test serves as a measured method to assess potential impairment, unlike making a quick arrest, which could be premature without sufficient evidence. Ultimately, employing this testing approach positions officers to make informed decisions that uphold the law while ensuring public safety.
