What Is Dennis’ Law?
Dennis’ Law is a 2017 amendment to the Illinois Vehicle Code that gives people riding bicycles on highways the same rights, including applicable right-of-way rights, and duties that apply to drivers of vehicles. The law was prompted by the 2015 death of Dennis Jurs and a court ruling involving the right of bicyclists to the right of way.
In 2015, Dennis Jurs was riding his bicycle in Hampshire Township, Illinois. He was struck and killed by an SUV at an intersection, and the driver was ticketed for failing to yield the right of way.
However, the driver challenged the citation, and a Kane County judge ruled that the traffic ticket was invalid, stating that bikes are not vehicles and that the right-of-way rules did not apply.
The backlash from the family and community eventually resulted in a new statute called Dennis’ Law. Governor Bruce Rauner signed the statute into law, and it went into effect on January 1, 2017.
A bicycle is not classified as a “vehicle” under 625 ILCS 5/1-217 because the statutory definition excludes devices moved by human power. Instead, 625 ILCS 5/11-1502 provides that every person riding a bicycle on a highway shall be granted all of the rights, including applicable right-of-way rights under Article IX, and shall be subject to the duties applicable to a driver of a vehicle. In Chicago, Chicago Municipal Code Chapter 9-52 also addresses bicyclists’ rights and duties as road users. Now, a driver must yield the right of way to a bicyclist when the cyclist is legally entitled to it.

Key Provisions of Dennis’ Law
This law was passed by both the Illinois House of Representatives and the Illinois State Senate. Public Act 99-0785 amended 625 ILCS 5/11-1502, and the amendment took effect on January 1, 2017. Before the amendment, the statute stated that traffic laws applied to people riding bicycles, subject to the exceptions in Article XV and provisions that could not apply by their nature. The amendment expressly clarified that a person riding a bicycle on a highway is granted all rights, including rights under Article IX, and is subject to the duties applicable to the driver of a vehicle. Read Public Act 99-0785.
Who Was Dennis Jurs?
Dennis Jurs was a 68-year-old cyclist from Hampshire who was killed in a May 2015 collision with a motor vehicle after a failure-to-yield citation was issued to the driver. After a Kane County judge dismissed the citation, Jurs’ family and supporters pushed for greater clarity in Illinois bicycle right-of-way law. State Representative Anna Moeller sponsored the legislation that became Public Act 99-0785. A 2026 Daily Herald report on Dennis Jurs and the law.

The Impact of Dennis’ Law on Bicycle Accident Cases in Chicago
The story of Dennis Jurs has changed how Illinois law protects bicyclists. Since they now have the same rights and responsibilities as drivers, they have an equal share of the road in right-of-way scenarios. Right-of-way laws are essential for determining who is at fault in an accident, especially when the collision results in serious injuries.
Illinois bicycle laws also address how drivers must safely pass cyclists on the road. Learn more about the Illinois three-foot passing law and the requirements that may apply when a motorist passes a bicyclist.
For example, say you arrive at a four-way stop in Chicago before another vehicle coming from a different direction. You have the right to go through that intersection just as a vehicle would before the second car.
If you get hit and suffer spinal cord injuries, the other driver would likely be liable for those injuries because they failed to follow the right-of-way rules for bikers and drivers.
In a real bicycle accident claim, a driver’s failure to yield may support a negligence claim when the facts show the driver violated a right-of-way rule. A cyclist’s right of way is determined under the same applicable traffic rules that govern other road users. However, Illinois modified comparative negligence still applies, so a cyclist’s own fault may reduce recovery and can bar recovery when the cyclist is more than 50% at fault.
