Factors Determining Auto Accident Liability and Liability Determination Methods

February 27, 2023

An auto accident victim must prove the defendant's liability in order to get compensation. Below are factors that determine liability and how you can evaluate them.


Factors Determining Liability


There are several factors that determine who is liable for an accident.


Driver Behavior


A driver's behavior is one of the most critical factors since each driver is responsible for their behavior and their car while on the road. The authorities will evaluate what the driver did before driving, and what the driver did just before, during, and after the accident.


Consider a driver who overtakes while the road ahead is not clear. If the driver's behavior causes a crash, they are liable for the accident because of that dangerous behavior.


Traffic Laws


The government uses traffic laws to control road users and keep them safe. Therefore, authorities will also consider the applicable traffic laws and determine whether the driver violated them. For example, most states have laws against making a U-turn while interfering with other traffic. Making such a U-turn makes the driver liable for the accident their actions might cause.


Vehicle Condition


A car's condition affects its risk of an accident. For example:


  • Bald tires increase braking distance and collision risk.
  • A busted headlight reduces visibility and increases the risk of collisions with other road users.
  • Defective brakes make stopping difficult in case of emergencies.


Drivers are responsible for maintaining their cars. Anyone who drives a defective car is liable for the accident the defect might cause.


Weather Conditions


Weather conditions increase the risk of accidents in several ways. For example:


  • Snow, ice, and water interfere with braking and make steering difficult.
  • Snowfall, rainfall, and fog reduce road visibility.
  • Windstorms make steering difficult.


Inclement weather is not an absolute defense against auto accident liability, since drivers must consider prevailing weather conditions. For example, if the road is wet, drivers should slow down to give themselves ample time to stop in case of an emergency.


However, bad weather can cause accidents even with the best driver behind the wheel. For example, a powerful wind can push a van into oncoming traffic. Therefore, the authorities consider prevailing weather when determining auto accident liability.


Liability Determination Methods


If you have an accident claim, expect that the parties involved will consider the above factors to determine fault. However, they need to gather the relevant facts first.


Examination of Physical Evidence


Interested parties should examine the physical evidence as part of liability determination. Physical evidence includes things like:


  • Road signs and markings
  • Vehicle damages
  • Skid marks
  • Injuries
  • Airbag deployment


For example, the absence of skid marks might mean that a driver did not break or try to stop upon spotting an emergency.


Scrutiny of Police Reports


The police will assess the physical evidence, interview witnesses, interview the victims, and use the information to generate an accident report. Other parties, such as the insurance company or accident victims, can use the report to determine liability for the accident.


Analysis of Witness Testimony


Credible eyewitnesses can shed light on the events before and during the accident. Consider a case where eyewitnesses testify that they saw a car going the wrong way, speeding, or changing lanes haphazardly. Such information may help reveal the liable driver.


Accident Investigations


Expect the insurance companies and the police to investigate the accident. The victim and defendant's legal team may also conduct their investigations. Investigations may involve analyzing the cars' event data recorders, talking to the victims, and tracing the victim and defendant's actions leading up to the crash.

A driver was seriously injured Saturday evening in a crash on Highway 99 near Fresno Street, according to the California Highway Patrol. The incident occurred on the southbound shoulder of the highway, where a commercial big rig had pulled over due to mechanical issues. As the truck sat stopped on the shoulder, a Ford Taurus traveling at high speed veered onto the same shoulder and slammed into the back of the trailer. Authorities say the Taurus appeared to be driving recklessly before the collision. The impact left the car heavily damaged, and the driver—who was not wearing a seatbelt—was rushed to a local hospital with major injuries. “Our hearts go out to the injured driver,” the CHP said in a statement. “This incident serves as a stark reminder that excessive speed and reckless behavior can have devastating consequences.” The CHP is using the crash as an opportunity to remind all motorists to drive responsibly, follow traffic laws, and always wear a seatbelt.

A tragic series of events unfolded Saturday morning in Sacramento when a police pursuit ended in a seven-vehicle collision that killed an innocent bystander. The crash occurred at the busy intersection of Florin Road and Greenhaven Drive. The incident began around 10:15 a.m. when Sacramento police received a call from a woman requesting assistance in retrieving her belongings from a home on Farm Dale Way. She expressed concern that her former partner, a known domestic violence suspect, might be present at the residence. Officers recognized the location from a prior domestic violence call the previous weekend. At that time, the suspect, Daniel Cunningham, 33, had already fled before officers arrived. During the ongoing investigation, police developed probable cause to believe that Cunningham had committed felony domestic violence. He was also identified as a parolee at large with an outstanding warrant. On Saturday, officers located Cunningham in a vehicle, which led to a high-speed chase heading westbound on Florin Road. The pursuit ended abruptly when Cunningham’s vehicle crashed into multiple cars at the Florin and Greenhaven intersection. According to police, the pursuit was short and officers had lost visual contact with Cunningham's vehicle just prior to the collision. Following the crash, Cunningham attempted to escape on foot but was quickly apprehended with the assistance of a police K-9. He was transported to a hospital for evaluation before being booked. Tragically, the crash claimed the life of 30-year-old Huyn Huu Duc Nguyen of Elk Grove, a bystander with no connection to the suspect. Details on other possible injuries, including whether children were involved, have not yet been confirmed. Sacramento Police spokesperson Anthony Gamble stated, “Our officers had the obligation to bring this person to justice. He made the decision to run. He made the decision to drive at a high rate of speed. He put himself and everybody else’s lives in danger by his actions and he caused this collision that took the life of somebody who was not involved in this whatsoever.” The California Highway Patrol has taken over the investigation into the crash itself. Cunningham faces multiple charges including parole violation, felony domestic violence, and felony evasion.

A tragic accident in Sacramento claimed the life of a woman on Tuesday evening, June 3, in the parking lot of a Bel Air grocery store on Rush River Drive. Around 6 p.m., Sacramento Police responded to reports of a pedestrian being struck by a vehicle. When officers arrived, they found a woman pinned between two vehicles with severe injuries. She was pronounced dead at the scene. Authorities later identified the victim as 36-year-old Linda Angelica Tracy, a Sacramento resident. According to police, she appears to have been the one operating her own vehicle when it accidentally struck and pinned her between another parked car. Two children were inside her vehicle at the time of the incident but were unharmed. The cause of the crash remains unclear, though investigators confirmed it was not a hit-and-run. Linda’s death has been officially classified as a motor vehicle accident by the Sacramento County Coroner’s Office. Her passing has left a deep void in the lives of those who knew and loved her. In a statement released by her family, Linda was remembered as “an exceptional mother and friend, who constantly put her family and community first.” They described her as someone who never hesitated to take on difficult and thankless tasks. A dedicated Girl Scout troop leader, school fundraiser, and the kind of parent always present for games, birthdays, and play dates, Linda was known for running a tight ship at home and for her love of planning family adventures. Soft-spoken but fiercely loyal, her family said she was the kind of person you wanted in your corner during tough times, someone who would do anything to protect the people she loved.
