How Do Most Car Accidents Happen?

Most car accidents are caused by negligence (source: NHTSA). That negligence can arise in diverse ways, but most of the time it involves:

Here is a closer look at how each of these factors contributes to car crashes and how negligence can be at play when they do.

Motorist Negligence & Car Accidents

More than 9 in 10 car accidents are caused by negligent drivers (source:NHTSA). This can include motorists in passenger vehicles, as well as commercial vehicles. Sometimes, several drivers may be negligent and end up causing a single wreck.

When motorists’ misbehaviors cause crashes, they tend to involve errors related to:

Perception and Recognition

More than 40% of wrecks happen because motorists fail to see key signals in their driving environment. This can involve completely overlooking these signals, as well as misperceptions and misunderstandings of these important cues.


Risky decisions behind the wheel cause about 30% of car crashes. These choices can include anything from drunk driving or using a cellphone to speeding, tailgating, or blasting through a red light.


About 11% of car accidents happen when motorists make risky maneuvers or when they mishandle a vehicle. This can involve oversteering or failing to adjust speeds in adverse conditions.


About 7% of auto accidents are caused by motorists failing to perform a necessary action. In most cases, it’s due to driver fatigue or a driver sleeping behind the wheel.

Vehicle Equipment Problems & Auto Wrecks

About 2% of all car accidents are caused by vehicle equipment problems (source:NHTSA). Often, these issues arise when:
  • Parts or components are inherently defective: Design flaws, manufacturing errors, and poor-quality materials can result in damage and equipment failure.
  • Improper installation causes malfunctions: Assembly errors or failures to properly replace vehicle systems can also result in equipment failure.
  • Vehicles aren’t properly maintained: Overlooking essential maintenance is another way vehicle equipment can end up failing on the roads.
Generally, the equipment that tends to fail most often on vehicles includes:
  • Tires: More than 1 in every 3 of equipment-related car accidents is caused by tire failures.
  • Brakes: More than 1 in 5 auto accidents result from equipment problems involving a brake system failure.
  • Steering, suspension, transmission, or engine systems: About 3% of equipment-related car crashes are caused by one of these systems failing.

Environmental Factors & Car Accidents

About 2% of all car accidents are caused by environmental factors, meaning the roads and/or the weather conditions (source: NHTSA). With environmental factors:
  • Poor road conditions can arise from the weather, dangerous roadway design, or failures to maintain the roads. In some cases, poor road conditions are the result of poorly set up highway work zones, missing traffic signs, or debris in the roads.
  • Weather is uncontrollable, but motorists can still adjust their actions accordingly. In fact, several crashes are caused by drivers failing to reduce their speeds in adverse weather.

Car Accident Statistics & Facts

To get a better understanding of car accident causes — and just how many crashes are caused by preventable negligence — check out some of the latest data on auto wrecks in the U.S. (sources: NHTSA and IIHS):
As shocking as some of these facts may be, they fail to depict the real trauma victims can suffer in car crashes. When it’s time to recover from that trauma, it’s time to contact Morris & Dewett Injury Lawyers. We can help you figure out what caused your car crash, so you can figure out how to get on the road to recovery.

How Do I Figure Out What Caused My Car Accident?

Investigations and evidence can uncover the causes of a car accident. In many cases, that means:
  • Taking prompt action immediately after a crash is best: This means calling police, taking pictures and videos of the scene, and gathering witness information when possible.
  • It may be necessary to revisit the accident scene: Debris from the crash, damaged roadway features, and even tire tread marks on the blacktop may help explain what caused the crash.
  • Requesting a copy of the police report can be helpful: Police reports for crashes are typically available within 10 to 21 days after a wreck. These reports can contain all sorts of information and potential evidence, including key details you may not otherwise be privy to, like breathalyzer test results, what others said after the crash, new witnesses, and more.
Depending on how a car accident happened — and how many other parties are involved — investigations and evidence for a crash can be quite complex. Nevertheless, it’s crucial to carry out a thorough investigation to identify all causes of a wreck and gather all possible evidence to support a claim.

Why Do I Need to Know What Caused My Car Accident?

The causes of a car accident will dictate the liable parties and how to go about suing them for the harm they’ve caused. With car accident causes and liability, it’s important to know that:
  • Liable parties may not be limited to those at the scene of a crash: The companies that make defective vehicle equipment or that put unsafe commercial drivers on the roads can be liable for their oversights, for example.
  • Multiple parties can share liability: These parties could include multiple drivers, motor carriers, vehicle equipment manufacturers, road maintenance contractors, and/or others.
  • Victims who share some fault may still be able to recover: Louisiana law allows victims to recover compensation even if they are partially liable, but the recoveries in these cases are typically reduced.

Can I Rely on an Insurance Company to Determine the Causes of My Car Accident?

No, it’s not a good idea to trust an insurance company to properly identify the causes — nor is it wise to assume that insurers will properly assign fault. The reason is that insurance companies don’t necessarily conduct neutral investigations. Nor are they interested in justice.

Instead, insurers are intent on protecting their interests and their profits. And they are known for using tricky tactics to try to pay out the least amount possible.

If you’re filing a car accident claim, that puts you in direct opposition to the insurance company’s interests. 

And it could mean that insurance companies:

Consequently, you should not automatically rely on the insurance company’s fault assessment, especially if you’re being wrongfully blamed for a wreck. It’s in your best interests to, instead, retain a lawyer who can help you determine fault.

When Do I Need a Car Accident Lawyer?

The sooner you retain a car accident attorney after a wreck, the better. A lawyer can immediately advise you and start investigating the crash while there is as much evidence available as possible. Plus, an attorney can determine liability and start helping you with key aspects of a claim, like:
