There are certain indications—a checklist, if you will—that a police officer is trained to look for. They will look for things like:

  • Are your eyes are watery?
  • Are your eyes are bloodshot?
  • In their opinion, is your voice is slurred?
  • Do you have an odor of alcohol?
  • In their opinion, are you steady or solid on your feet?
  • Do you seem to be making statements that are coherent and clear?

Those are the sorts of things that they will typically look for.

They’ll also look for other factors. Are there other passengers in the car? Are those people drunk? They also look to see how a person drove. Did they think that person did a weave?

Ultimately, when police officers pull you over for a DUI stop, they are looking for anything that they think supports their view that someone is driving under the influence.

Sometimes it’s a game of pick and choose. You may not have all of these signs of a DUI. In fact, you may not show most of these signs. Police officers can pick one or two supporting factors as justification for why they believe that you were driving under the influence.

So while it’s true that there are certain things that police officers look for, they are oftentimes really just looking for certain facts that they can point to as evidence of a DUI.
