As any Illinois traffic and DUI lawyer knows, you must signal at least 100 feet before turning in a non-rural area. Failure to do so constitutes a traffic offense.
An arrest in Illinois for DUI often begins with a simple traffic offense. Common violations include speeding, improper lane usage (“weaving” or “swerving”), and disobeying a stop sign or stoplight.
Sometimes, there does not even have to be a traffic violation. If properly designed, police have the right to erect DUI roadblocks.
And even minor violation of the Illinois Vehicle Code can lead to a stop. This can be something as simple as a burned out license plate light, an expired license plate tag, an obstructed windshield (an air freshener hanging from the mirror) or failing to dim your headlights to oncoming traffic.
As a matter of fact, a Springfield Illinois DUI arrest began with the police pulling over the driver for not using his turn signal within 100 feet of an intersection. You probably would not be stopped in broad daylight for failing to use your turn signal. It is possible the police are using this minor offense as a pretext (“excuse”) to investigate a DUI at 11:00 in the evening.
