What are the Clues Police Use to Pull You Over For OWI?

The police must have reasonable suspicion that some type of traffic violation or crime has occurred in order to pull you over. The police are trained to look for several “clues” of drunk driving, including:

  1. problems maintaining proper lane position (swerving);
  2. speeding and braking issues;
  3. attention issues (e.g. delayed response to traffic signals);
  4. judgment mistakes (e.g. running red light, risky lane switching).

If the police notice any of these issues, they may pull you over and begin their investigation to determine if you are driving drunk. I know the common mistakes (and assumptions) police make in improperly pulling you over and will attack every step of the investigation.
