Topic overview

This is the densest chapter in the handbook, covering the everyday rules that come up on almost every drive: what to do when a police officer stops you, the distracted-driving and cellphone law, seat belt and child restraint requirements, and speed limits by road type. It also details how to behave around work zones, emergency vehicles, school zones, and funeral processions.

A large portion is dedicated to right-of-way — who yields at a four-way stop, at an uncontrolled intersection, when turning, and when a pedestrian is present — along with the rules for passing, lane usage, signaling, turning, and roundabouts. These right-of-way scenarios are some of the most frequently tested material because they require applying a rule to a specific situation rather than just recalling a fact.

A common mistake is assuming cellphone rules are all-or-nothing: hands-free use is only allowed for drivers 19 and older, and even hands-free video streaming or social media use is illegal regardless of age. Another is not knowing exactly where passing is prohibited — within 100 feet of an intersection or railroad crossing, on hills or curves with blocked sightlines, and always in a construction zone.

At an uncontrolled intersection, when two vehicles arrive from different roadways at the same time, who has the right of way?

The vehicle on the left must yield to the vehicle on the right.

Is hands-free cellphone use always legal while driving in Illinois?

No — hands-free use is only permitted for drivers age 19 and older, and using it to stream video or access social media is illegal for any driver.

Where is passing another vehicle prohibited on a two-lane road?

Within 100 feet of an intersection or railroad crossing, on a hill or curve where oncoming traffic can't be seen, and in any construction zone, which is always a no-passing zone.
