Most research from national traffic safety agencies shows that the majority of car accidents in the United States are caused by human error, such as inattention and speeding. These behaviors affect reaction times and roadway awareness, which increases the risk of a wreck.
If you need help understanding how driver error contributed to your crash, speak with a Port St. Lucie personal injury attorney at Lytal, Reiter, Smith, Ivey & Fronrath.

Defining human error as a contributor to car accidents
Human error refers to the choices and behaviors that directly influence crash risk. These include lapses in judgment, delayed reaction times, misreading traffic conditions, or failing to follow the speed limit.
Common examples include turning without checking for oncoming traffic, drifting out of a lane, driving while tired, or reacting too slowly to a red light or stopped vehicle. When these errors happen, they set the stage for preventable crashes and make it easier for insurance companies to attribute fault.
What the numbers say about human error and car accidents
Recent reports from the National Highway Traffic Safety Administration (NHTSA) continue to show that human error accounts for most car accidents. While the exact percentage varies depending on the study, national crash investigations consistently link the majority of collisions to driver behaviors rather than vehicle defects or environmental factors.
Distracted driving is a main contributor to human errors while driving
In 2023, there were 611 nonoccupants (like pedestrians and cyclists) killed in distraction-affected traffic crashes. Distraction, like texting and eating, can pull a driver’s attention away from the road for a few seconds or for several minutes. This creates dangerous gaps in awareness. These distractions also affect reaction times and make it harder to respond quickly when traffic conditions change.
Excessive speed is a common erroneous decision
Speeding was a factor in 29% of all traffic fatalities in 2023. Driving faster than the speed limit reduces the time a driver has to avoid hazards and makes it harder to maintain control. Speeding drivers are also more likely to misjudge distances and underestimate stopping time.
Failing to yield to the right of way
A driver’s failure to yield to the right of way is a significant contributor to Port St. Lucie car accidents. This behavior can include things like:
- Running red lights
- Failing to stop at a stop sign
- Failing to adequately check your blind spot before merging
Violating the state’s right-of-way laws is a large contributor to motorcycle accidents. The combination of a smaller vehicle and deviating from the expected behavior on the road can be a lethal combination. According to the National Safety Council (NSC) statistics on improper driving and road rage, failure to yield contributes to 7.9% of accidents.
Driving under the influence is a common lapse in judgment
Driving under the influence of drugs or alcohol is the cause of thousands of accidents every year, and kills one person every 42 minutes. Driving under the influence slows your reaction time, impairs your judgement, and throws off balance and coordination. The NTHSA reports that drunk driving with a BAC of .08 makes you 4x more likely to have an accident than those with a BAC of 0.
Driver error and truck accidents
The Federal Motor Carrier Safety Administration (FMCSA) conducted a large truck crash causation study to evaluate the causes of truck accidents and found that 87% of accidents were a result of driver error. However, we can surmise that the percentage of truck accidents attributed to human error is likely higher than that when we consider errors in maintenance and loading.
