Illinois Traffic Laws & Right-of-Way
⏱ ~3-min readAceMark Guide
What this topic is really about
When a school bus displays flashing red lights and an extended stop arm on a two-lane undivided road, traffic in both directions must come to a complete stop. You may not move until the bus resumes motion or the lights are turned off. On a divided highway with a physical barrier, only traffic following the bus must stop.
Illinois law requires you to yield to approaching emergency vehicles by pulling over to the right edge of the roadway and stopping until they pass. If you are in an intersection, clear it first, then pull over. Never stop in the middle of an intersection, and do not follow an emergency vehicle closely.

- Failing to buckle up is a primary offense, meaning police can stop and ticket you for that alone.
