Rear-End Accident Fault in Missouri: Rights & Options

When another driver strikes your vehicle from behind, Missouri law generally assumes that the rear driver is at fault. This is commonly known as the rear-end collision doctrine. Missouri law requires drivers in Missouri to maintain a safe distance and remain alert at all times. So, if a driver hits the back of another vehicle, the assumption is that he or she failed to exercise due care in one or more ways.

However, this is a “rebuttable presumption,” which means that the law doesn’t automatically find the rear driver at fault in every scenario. Each case depends on its specific facts, and fault can shift if there is credible evidence that rebuts that initial assumption.

How Fault is Determined in a Missouri Rear-End Accident

In Missouri, the rear-end collision doctrine is a legal rule that presumes that the driver who hits another vehicle from behind is at fault. This is based on the expectation that motorists must not follow other vehicles too closely and remain attentive to traffic and roadway conditions to avoid such collisions. This duty is reflected in Missouri Revised Statutes § 304.017, which requires drivers to keep a reasonably safe distance from the vehicle ahead.

If you were injured as the result of a driver hitting you from behind, the law requires that you establish a few basic elements for your claim. First, you must show that you had a legal right to be on the roadway. Second, you must prove that your vehicle was struck from behind by the defendant’s vehicle. Third, you must demonstrate that you were not acting negligently or carelessly at the time. One example of such negligence would be making an abrupt or unsafe stop. Once a plaintiff (injured party) proves these elements, the presumption of fault shifts to the rear driver who may then try to rebut it with evidence explaining why the collision was not because of negligence or carelessness on his or her part.

When the Rear Driver is At Fault: Common Causes

In Missouri rear-end accident cases, there are certain driving behaviors that clearly point to fault on the part of the rear driver. Missouri law (RSMo 304.012) requires every driver to operate a vehicle with the highest degree of care.

Here are some of the common examples of driver negligence that often lead to rear-end crashes.

Tailgating: Often, rear-end crashes occur simply due to not leaving enough space in front of the vehicle. The Missouri State Highway Patrol’s statistics show that tailgating or following too closely caused 19,339 collisions statewide, which involved 37 fatalities and 6,273 injuries. When a driver is following too closely, he or she typically does not have enough time to stop, making a collision much more likely. RSMo 304.017 requires drivers to maintain a safe distance and not follow too closely. Drivers must take into consideration speed, weather, traffic and roadway conditions. Under Missouri law, when a driver rear-ends another vehicle while following too closely, it directly supports the presumption that the rear driver is at fault.

Distracted driving: When drivers are distracted, they fail to notice traffic conditions. Looking at a phone, adjusting radio, GPS or other controls, eating or even talking to a passenger, can delay reaction time and cause a crash. If a driver’s attention is not fully on the road, he or she may not see the vehicle in front slowing down or stopping, which tends to result in a rear-end crash.

Speeding: Driving too fast can reduce the time and distance that is needed to stop safely. Even if a driver is paying attention to the road, excessive speed can make it very difficult to stop when traffic ahead slows down. In a rear-end accident case involving a speeding driver, the injuries and damages are also greater from the increased force of impact. This often plays a part in a personal injury claim to suggest and highlight the negligence of the rear driver.

Unsafe driving in hazardous conditions: Driving slowly and increasing the following distance is a requirement for all drivers in unsafe weather, road and traffic conditions such as snow, rain, fog, traffic congestion or when driving on poorly maintained roads. Rear-end collisions that are often preventable happen when drivers fail to compensate or adjust to these conditions.

When is a Lead Driver at Fault?

In certain cases, the driver in front or other factors that are involved can result in a rear-end collision. Some of these include:

Brake checking: Drivers who create intentional and dangerous traffic conditions by making sudden, unnecessary stops for instance, to intimidate or retaliate against another driver are not protected by Missouri law.

Broken brake lights: All drivers in the state have a duty to keep their vehicles in safe working condition. If a vehicle’s brake light is not functioning, the rear driver may not have a warning or enough time to react. And a claim can be made in such cases that the driver ahead did not maintain his or her vehicle properly. The statute, RSMo 307.075 is applicable here as it requires motor vehicles to be equipped with functioning rear or tail lamps that emit a red light to make a vehicle visible at night. Also, the red light must be visible from a specific distance.

Reckless lane changes: Missouri law requires drivers to make safe lane changes. If a driver merges into another lane suddenly and is hit from behind, then he or she can be held responsible.

Reversing into traffic: A driver who is moving in reverse has a duty to make sure that he or she is backing up in a safe manner and not presenting a hazard to approaching traffic. The reversing driver can be held liable if hit from behind in such cases.

Mechanical failure: Under Missouri law, a mechanical failure such as brake failure during a rear-end crash can be seen as unforeseeable or unavoidable in certain instances and not linked to carelessness. A rear driver maintaining a safe distance may avoid liability here.

Chain-reaction crashes: In an investigation, fault and liability tends to be shared or reassigned in chain-reaction crashes as several vehicles are involved. So, if an initial collision pushes a driver into the rear of another vehicle, then he or she may not be liable for the resulting second crash.

The cost of a car accident settlement can add up very quickly and have long-term financial consequences. Not only does an injured victim pay his or her insurance deductible upfront, but also quickly faces escalating medical bills that can become overwhelming. Even injuries such as whiplash or soft tissue injuries can still require physical therapy and other costly treatment. Also, increasing insurance premiums and attorneys’ fees and court costs in the event another driver filing a personal injury lawsuit contribute to the cost of the accident.

Shared Fault – How Missouri’s Comparative Negligence Law Works

Missouri follows a pure comparative fault system, which means that fault for a rear-end accident can be divided among all parties involved. Instead of being barred from recovery if you share responsibility, you can still recover damages. Your compensation is simply reduced by your percentage of fault.

For example, if your total damages are determined to be $50,000 and a court finds that you were 20% at fault for the accident and the other party was 80% at fault. In this case, you can still recover an amount that is reduced in value by your share of fault. This means you would receive $40,000 instead of the full $50,000.

RSMo §537.765 allows juries to assign percentages of fault and adjust damages accordingly and provides a framework for Missouri’s comparative fault system. The system was firmly established by the Missouri Supreme Court in Gustafson v. Benda (1983), which replaced the older contributory negligence rule that barred recovery if the plaintiff (injured party) contributed to the accident. The pure comparative fault system ensures that each party is held financially responsible only to the extent of their share of liability.

How Insurance Companies Handle Rear-End Claims

In a rear-end accident claim, the insurance adjuster investigating the accident determines who is at fault and then estimates damages. Even if the rear driver is presumed to be at fault, adjusters review all available evidence to make a determination. In such cases, you should support your claim by submitting clear photos of vehicle damage, the accident scene and any visible injuries along with the police report, eyewitness statements and dashcam footage, if available. You should also submit medical bills and repair estimates to help establish the extent of your damages and losses.

The insurance adjuster, after assigning liability, calculates a settlement amount meant to cover repairs, medical expenses and in some instances, lost wages. These initial settlement offers can be much lower than your claim. You should not accept any settlement offer before speaking with your Missouri car accident lawyer. Your accident attorney will work with you on the best approach to negotiate a fair settlement.

What to Do After a Rear-End Accident in Missouri

1. Call 911 immediately

Report the accident and request police assistance at once. An official report helps document what happened at the time and will help your attorney deal with insurance companies.

2. Get medical care right away

Even if you “feel fine,” go to the emergency room or your doctor as soon as possible. Injuries such as whiplash may not show symptoms immediately, and prompt evaluation creates a record linking injuries to the crash.

3. Collect evidence at the scene

Take photos of vehicle damage, license plates, road conditions and any visible injuries. Get contact information and insurance details from the other driver in addition to names and statements from witnesses, if possible.

4. Do not give a recorded statement to the other driver’s insurer

Insurance adjusters may contact you soon after the accident. However, you are not required to provide a recorded statement. In fact, doing so without the counsel of your attorney can harm your car accident case.

5. Contact a lawyer before accepting any settlement

An experienced attorney can protect your rights, handle communications with insurers. Your attorney will also help you avoid an unfair settlement offer and pursue fair and full compensation for medical bills, lost wages and other damages. You should contact a Missouri car accident lawyer immediately after a rear-end collision.

Frequently Asked Questions

What if someone slams on their brakes and you hit them?

If a driver suddenly slams on their brakes and you rear-end them, you may still be presumed at fault. But liability is not assigned without an investigation. If the other driver’s actions are found to be unreasonable or unsafe, then your liability may be re-assigned. Even if you are found to be at fault for a certain extent, under Missouri’s comparative fault rules, our lawyers will argue shared responsibility and work to reduce your percentage of fault so you can still recover compensation.

What if the front car had broken brake lights?

If the front car had broken brake lights, that can shift part of the fault to that driver because he or she failed to give proper warning before slowing or stopping. Under Missouri’s comparative fault system, you can still recover compensation that is reduced by your percentage of fault.

If someone cuts me off and I hit them, who is at fault?

If someone cuts you off and you hit them, they may be at fault for making an unsafe lane change or failing to yield. Even if you are found to bear some responsibility due to say, following too closely or not being able to react in time, a proportional amount can be recovered for your losses under Missouri’s comparative fault rules.

Will my insurance go up after a rear-end accident?

Your insurance may go up after a rear-end accident, especially if you’re found at fault since insurers now view you as a higher risk. However, the exact increase depends on your driving history, your insurer’s policies and whether any accident forgiveness applies.

Can I still recover money if I was partly at fault?

Yes. Missouri follows a pure comparative fault system. So, you can still recover money even if you were partly at fault. Your compensation is simply reduced by your percentage of responsibility.

Does bad weather mean no one is at fault?

No. Bad weather does not eliminate fault. Drivers are still expected to adjust their speed and driving to the conditions, even if they are hazardous. If a driver fails to do so, he or she can still be held partially or fully responsible for the accident.
