Are Rear-End Collisions Always the Rear Driver’s Fault?

Are rear-end collisions always the rear driver’s fault? Although the rear driver is usually presumed liable, the front driver may share or bear fault if they reversed, rolled back, had non-functioning brake lights, cut in unsafely, brake-checked, stopped illegally, or braked unreasonably and suddenly. 

Our New Orleans rear-end accident lawyer can examine the circumstances of your accident.

Reversing or Rolling Back Means The Front Driver Likely Caused the Collision

Consider a typical scenario. The rear vehicle has come to a halt behind another vehicle. The driver of the front vehicle fails to engage the gears and takes their foot off the brake. The vehicle rolls back and collides with the vehicle behind it. In this instance, the driver in front was driving negligently, while the driver behind their vehicle was likely not negligent. 

Another way this may play out is a person accidentally reversing into a vehicle behind them. Their duty of care would be to ensure it was safe to reverse. Failing to do so would constitute negligence. In the most egregious example, an insurance fraudster deliberately reverses into the rear vehicle and then tries to claim compensation.

Non-Functioning Brake Lights May Lead to a Finding That The Driver of The Front Vehicle Shares Fault

When driving in traffic, brake lights instantly warn a following driver that a vehicle ahead is braking. If they are maintaining a safe following distance, they have time to react. However, if the front car’s brake lights aren’t working, the rear driver has less time to react. 

Courts may assign shared fault in such scenarios, but under certain circumstances, they might rule that the driver of the car ahead is at fault. Investigators may analyze factors like speed, following distance, and stopping distance to determine whether the rear driver was inattentive. 

Unsafe Lane Changes Or Merging

Reckless or unsafe driving in the form of cutting in may mean that rear-end collisions are not the rear driver’s fault or that they are only partly at fault. When a driver cuts in front of another vehicle and then slows, the rear vehicle may not have time to brake, leading to a rear-end accident. 

Cutting in and then slowing is particularly risky when the following vehicle is a large truck. Its weight and momentum mean it requires more space to slow down or stop. An experienced truck driver adjusts their following distance to compensate, but if someone cuts in, they may not have time to react if that vehicle suddenly slows. 

Courts View Brake-Checking as Reckless or Negligent Conduct

Intentionally braking suddenly to annoy or intimidate a following driver can lead to a collision. It is often a symptom of road rage, and Louisiana courts generally view it as reckless or negligent conduct on the part of the driver in front. If it is proven, a court might find the front driver primarily at fault. 

Courts will require evidence from witnesses, CCTV, or dashcam footage to show that the driver in front braked intentionally or unreasonably and that their conduct caused the collision. If the rear driver could have avoided the crash, they may still share fault. 

Illegal or Unreasonable Stopping and Rear-End Collisions in Louisiana

When a driver stops in a travel lane without justification, in a no-stopping zone without a reasonable cause, or due to a breakdown without activating their hazard lights, a court may find them negligent. Negligence equates to fault, whether shared or found to be attributable to a single party. 

There are times when stopping or sudden braking is reasonable. For instance, the driver in front stopped to avoid a hazard. It may mean sudden braking, for example, to avoid a pedestrian. In that case, the rear driver remains responsible. However, if you slam on the brakes or stop without a valid reason, fault for a rear-end accident may shift from the driver of the following vehicle to the driver of the vehicle in front, or both drivers may share fault.  

Courts Presume That Rear-End Collisions are the Rear Driver’s Fault Unless They Can Challenge This Assumption

The presumption of fault for rear drivers stems from La. R.S. §32:81, which requires drivers to maintain a reasonable following distance. This distance should be prudent, allowing enough space to slow or stop based on speed, traffic conditions, and road conditions. 

If a driver rear-ends another vehicle, the fact that they collided with the vehicle in front creates a presumption that the rear driver was following too closely. However, the rear driver can challenge this by showing that the front driver contributed to or caused the accident through negligent driving. 

How Fault Impacts Compensation After an Accident in Louisiana

Decisions on who is at fault when you get rear-ended in a car accident, or if you rear-end another car, directly impact your right to compensation. In the past, any person with a share of fault, however small, had to pay for their share of damages in proportion to their degree of fault. From January 1st, 2026, Louisiana Civil Code Article 2323 applies. It provides for:

• Compensation for parties who were less than 51% at fault in an accident
• No right to compensation if a party’s share of fault is 51% or more
• Compensation based on the percentage of fault allocated to other drivers when the plaintiff is 50% at fault or less

To illustrate this, let’s suppose you rear-ended another vehicle, but its driver was 51% at fault. You can claim compensation, but you will only receive 51% of your damages. The other driver cannot claim any damages. A ruling on fault depends on evidence showing who was negligent and to what degree. That means rear-end collisions are not always the rear driver’s fault.

Courts Start by Presuming the Rear-End Driver Was at Fault, But Will Consider The Circumstances

Accident cases are often far from straightforward, and you should not assume that rear-end collisions are always the rear driver’s fault. If the rear driver or their lawyers can show that the front driver was negligent, a court might find that the front driver was at fault. Courts often find that both drivers were negligent to some degree.
