Can You Sue Someone After You Rear-End Them?

 Posted on April 30, 2026 in Car accidents

Maybe you’ve heard that the driver who rear-ends another car is always considered at fault, even if they couldn’t have prevented it. If you’ve recently been the back driver of a rear-end accident, this thought can be panic-inducing. Breathe a little easier: fault for rear-end car accidents in Illinois isn’t so black and white, and you may still be able to take action against the driver of the car in front of you if you got hurt.

If you were in a rear-end collision in 2026, a Glenview personal injury attorney can help you know where you actually stand.

Why Do People Say the Back Driver Is Always at Fault for Rear-End Car Accidents?

The idea that the driver following the other car is always at fault for a rear-end accident isn’t completely baseless. In many cases, the back driver is in fact presumed liable for rear ending the car in front of them.

This is because the law requires that all drivers be aware enough of their surroundings to respond to sudden changes, like the car in front of them braking suddenly. There's a general expectation under Illinois traffic law that drivers maintain a safe following distance. Drivers who were distracted or following too closely will find it difficult to prove that they weren’t at least partially at fault for a rear-end accident.

There are, however, many circumstances in which a driver behind another car has no control over the fact that they rear-end the other car.

When Can the Front Driver Be at Fault for a Rear-End Accident?

There are actually many circumstances where the front driver bears all of the responsibility for a rear-end collision. Some situations in which the front driver may share at least some fault include:

• The front driver cutting you off with little to no warning, especially when approaching a red light

• The front driver’s brake lights being broken or malfunctioning

• The driver ahead of you reversing into you unexpectedly

• The other driver stopped abruptly in the middle of a highway or in a no-stopping zone

• Distracted or erratic driving on the part of the other driver before the crash

• One driver fails to stop in time, rear-ends another car, and then pushes that car into the driver ahead.

Whatever the situation, if you think another driver is at fault for a rear-end accident you were hurt in, you should talk to a lawyer. 

How Is Fault Divided in a Car Accident in Illinois?

Illinois follows a rule called "modified comparative fault" under 735 ILCS 5/2-1116. This means several drivers can share responsibility for an accident, and damages are reduced based on each person's percentage of fault. 

As long as you're found to be 50 percent or less at fault, you can still recover compensation. If you're found more than 50 percent responsible, you can't recover anything. Evidence, especially in the case of a rear-end accident where you may be assumed to be at fault, is vital for proving that you were less than 50 percent at fault.

What Evidence Can Help Your Rear-End Accident Case?

For these cases, documentation is your best defense. This can include:

• Traffic or dashcam footage showing the other driver's behavior before impact

• Photos of the scene, including skid marks, road conditions, and vehicle positions

• Witness statements from anyone who saw what happened

• The police report, which may note contributing factors like non-functioning brake lights

Gather what you can immediately after the crash, and don't wait to meet with an attorney. Evidence disappears quickly, and the other driver's insurance company will begin building their version of events right away.
