Understanding Illinois Right-of-Way Laws

3 min read

Right-of-way laws are essential for maintaining order and safety on Illinois roads. Whether you're navigating intersections, merging onto highways, or encountering emergency vehicles, understanding who has the right-of-way helps prevent accidents and ensures compliance with state laws. This guide outlines the key right-of-way rules in Illinois as of 2025, including recent legislative updates.

Intersections and General Right-of-Way Rules

At intersections without traffic signals or signs, the vehicle that arrives first has the right-of-way. If two vehicles arrive simultaneously, the driver on the left must yield to the driver on the right. This rule helps manage traffic flow and reduce confusion at uncontrolled intersections.

When turning left at an intersection, drivers must yield to oncoming traffic that is close enough to pose a hazard. This applies when turning into alleys, private roads, or driveways as well. It's crucial to ensure that the path is clear before proceeding with a left turn.

Drivers entering a highway from a private road, alley, or driveway must yield to all approaching vehicles on the highway. This rule ensures that traffic on the main road is not disrupted by entering vehicles.

Merging and Yielding

In situations where traffic lanes merge, such as highway on-ramps, drivers must adjust their speed and position to merge safely without causing collisions. The responsibility lies with the merging driver to ensure a smooth and safe entry into the flow of traffic.

When approaching a yield sign, drivers must slow down and be prepared to stop if necessary. They must yield to any vehicle in the intersection or approaching on another roadway so closely as to constitute an immediate hazard.

Pedestrians and Crosswalks

Pedestrians have the right-of-way at crosswalks and intersections, whether marked or unmarked. Drivers must stop to allow pedestrians to cross safely. This rule emphasizes the importance of pedestrian safety and the driver's responsibility to be vigilant.

Emergency Vehicles and Scott’s Law

Illinois' Scott's Law, also known as the "Move Over" law, mandates that drivers yield the right-of-way to authorized emergency vehicles displaying flashing lights. When approaching such vehicles, drivers must change lanes if possible, or reduce speed and proceed with caution if changing lanes is unsafe.

As of 2025, Scott's Law has been expanded to include a broader range of vehicles and scenarios. Drivers are now required to yield the right-of-way to any authorized emergency vehicle engaged in work upon a highway, whether stationary or not, and displaying flashing lights. This includes yielding to emergency workers and pedestrians directly involved in the emergency scene.

Violations of Scott's Law can result in severe penalties, including fines up to $10,250 and potential license suspension, especially if the violation leads to injury or death.
