How Do Police Officers Detect Drunk Drivers?

Police employ a number of investigative tactics to detect drunk drivers. Some of the practices they use include:

  • Identifying driver tendencies: Identifying factors of drunk driving include swerving, tailgating, quick acceleration and panic braking. It is important to remember, however, that these actions can have explanations aside from driving under the influence.
  • Observation: Police officers who suspect drunk driving will carefully observe the driver for signs of inebriation, including red eyes, slurred speech and the scent of alcohol on the breath.
  • Breath tests: Officers may administer preliminary breath tests on the roadside, and/or evidentiary breath tests after a lawful arrest.
  • Field sobriety tests: These tests are intended to detect impairment by forcing the subject to undergo a number of physical challenges.

No matter how compelling the police officers find their evidence, an experienced DUI defense lawyer can employ their own investigation to expose weaknesses in the case.
