This is What Police Are Looking for When They Suspect You of DUI


There are certain behaviors that police are looking for when watching for suspected impaired driving. Though some of the behaviors indicative of DUI are fairly obvious, there are some you might not think of. Here’s a list of common indicators of drunk driving that might lead to a pullover, or if you’ve already been pulled over, a DUI charge.

  1. Turning with too wide of a turn radius, or making an illegal turn
  2. Inability to stay within your lanes, or driving on the lines
  3. “Appearing to be drunk” (talk about ambiguity)
  4. Driving at night with headlights off
  5. Constant flux in acceleration
  6. Signaling left when you’re turning right (or vice versa)
  7. Sudden braking or stopping
  8. Drifting (not the Tokyo kind – that’s a whole other ordeal)
  9. Driving 10 mph under the limit. Funny enough, the National Highway Traffic Safety Administration does not consider speeding as a sign of impairment, but police have found a way around that by saying that speeding is a risk behavior, and impairment leads to risk-taking.

Once you’re pulled over, they’ll be looking for physical signs of impairment, such as:

  1. Red in the face – flushed skin, bloodshot eyes
  2. The smell of alcohol
  3. Slurred speech
  4. Trouble producing your license and insurance
  5. Inappropriate attitude (unnecessarily combative, even being too jovial)
  6. Inability to divide attention (this is one reason they keep talking while you’re grabbing your documents – they want to distract and frustrate you to reveal your impairment)

Of course, many of these signs do not necessarily indicate impairment. You could be tired, you could be emotionally distraught – there are plenty of other reasons for the above behaviors, but this is what police are looking for.
