When a crash happens in an instant, the question of who caused it can take months to resolve. Speed is one of the most powerful pieces of evidence in that process, and if one driver was exceeding the limit, the ripple effects on fault determination can be significant and far-reaching.

If you were injured in a crash and suspect the other driver’s speed played a role, understanding how that factor is evaluated legally can make a real difference in your case. At Hollis Law Firm, we work with injured people to build strong car accident cases grounded in evidence and focused on fair compensation. We believe our role is to guide you, educate you on your options, and take action based on the decisions you make.

How Speeding Is Used to Establish Negligence

In personal injury law, fault is generally tied to negligence, meaning a driver failed to act with reasonable care under the circumstances. Speeding is one of the clearest examples of that failure. Every driver has a legal duty to obey posted speed limits and adjust their speed based on road and weather conditions. When a driver exceeds that standard, they have breached their duty of care, which is one of the core elements needed to establish a negligence claim.

What makes speeding particularly significant in fault analysis is that it often appears in the official record. If a police officer noted speed as a contributing factor in the crash report, or if the driver was cited for a speeding offense, those findings carry real weight. According to the National Highway Traffic Safety Administration, speeding was a factor in 28 percent of all fatal crashes and led to over 11,700 deaths in 2023 alone. That data reinforces why courts and insurance adjusters treat speed as a serious indicator of fault.

What the Evidence Can Prove

Beyond a police report, multiple forms of evidence can establish speeding in a civil case. Witness statements, traffic camera footage, event data recorders (commonly called “black boxes”), and accident reconstruction analysis can all help demonstrate that a driver was traveling at an unsafe speed. Skid marks and the severity of vehicle damage are also commonly examined to estimate how fast a vehicle was moving at the point of impact.

These types of evidence are especially valuable in rear-end accidents, where the force of impact often indicates whether the striking driver had adequate time and distance to stop.

Comparative Fault and How Speeding Fits In

Kansas and Missouri both follow comparative fault rules, which allow fault to be shared among multiple parties. Even if a speeding driver caused most of the harm, an injured person may be found partially at fault for their own actions, such as failing to signal, making an unsafe lane change, or driving while distracted. In Kansas, a modified comparative fault rule applies, which means if you are found to be 50 percent or more at fault, you cannot recover compensation. Missouri uses a pure comparative fault standard, allowing recovery regardless of your percentage of fault, though your award is reduced accordingly.

This is why the framing and argument of fault matter so much. If the other driver was speeding, that needs to be clearly established and attributed appropriately. Factors like distracted driving or impairment from alcohol often compound speeding-related crashes, and building a complete picture of what happened requires careful investigation.

When Speed Alone Does Not Decide the Case

It is worth noting that speeding does not automatically make someone entirely at fault. Circumstances still matter. A driver going slightly above the speed limit may share fault with someone who ran a red light. The proportional assignment of fault depends on how each party’s conduct contributed to the crash. This is precisely where legal guidance becomes valuable because the specific facts of your situation, the applicable state law, and the evidence available all shape what compensation you may be able to recover.

Injuries in speed-related crashes can be severe and life-altering. Spinal cord injuries are among the most devastating outcomes, and the costs associated with long-term care, lost income, and pain and suffering deserve to be fully accounted for in any claim.
