Illinois DUI Traffic Stop – Why Was I Stopped?

Reader’s Question:

When I was arrested for DUI here in Evanston, Illinois, I really didn’t understand why the officer asked me to pull over. I don’t remember that I committed any traffic violation. What are the possible reasons why an officer could ask a driver to pull over because of a DUI suspicion?

On your DUI arrest in Evanston,, the police officer should have had a ‘reasonable suspicion’ to pull you over. It may constitute a ‘reasonable suspicion’ if the police officer observed that your vehicle was swerving over lanes. Similarly, if you were driving with a broken headlight, broken taillight, driving too fast or even with your high-beams on (in traffic), that could also be sufficient ‘reasonable suspicion’ to pull you over. But if after an investigation of your DUI case that it is discovered that your broken taillight was nothing more than a crack in the red plastic, or if you were driving with your high-beams on and a significant distance from other vehicles, the DUI stop would be considered illegal and an appropriate motion to suppress and could result in an order excluding all evidence after the illegal stop.

The evidence that can be excluded would be the police officer’s observations, breath test results, field sobriety tests and anything else that the state attorney might rely on to obtain a conviction. It has also been found that minor swerving within lanes could be an insufficient reason for an officer to stop your vehicle. Similarly, since newer vehicles are equipped with three or more tail lights, a DUI stop for a malfunctioning tail light is improper if two of the three tail lights on your vehicle were operating properly
