Common Car Accident Scenarios: Causes & Determining Fault in San Bernardino, CA

Car accidents happen every day across San Bernardino. If you’ve been involved in a crash, it’s normal to feel overwhelmed and unsure of what comes next. One of the biggest questions people have is: “Who was at fault?”

Understanding common accident scenarios and how fault is determined under California law can help you protect your rights and move forward with more confidence.

Why Fault Matters in California

Why Fault Matters in California

California follows a pure comparative negligence system. In simple terms, this means more than one person can share responsibility for a crash. Your compensation may be reduced based on your percentage of fault.

For example, if you are found 20% responsible for an accident, your recovery would be reduced by 20%. Because of this, determining fault isn’t just a technical detail; it can directly affect your financial recovery.

Common Car Accident Scenarios in San Bernardino

While no two accidents are exactly alike, many follow familiar patterns. Below are some of the most common types of crashes and how fault is usually evaluated.

Rear-End Collisions

Rear-end crashes are especially common in stop-and-go traffic and crowded intersections. These accidents often happen quickly, leaving little time for drivers to react.

Common causes include:

  • Following too closely
  • Distracted driving
  • Sudden or unexpected stops

In most cases, the driver who hits the vehicle ahead is considered at fault for failing to maintain a safe following distance. That said, there are exceptions. If the lead driver suddenly reverses or has broken brake lights, fault may be shared.

Left-Turn Accidents

Intersections are one of the most dangerous places on the road, particularly when drivers attempt left turns across traffic. These situations require careful judgment and timing.

Common causes include:

  • Misjudging the speed or distance of oncoming vehicles
  • Failing to yield
  • Ignoring traffic signals

The driver making the left turn is typically responsible because they are required to yield. However, if the oncoming driver was speeding or ran a red light, liability may not be so clear-cut.

T-Bone (Side-Impact) Collisions

Also known as broadside accidents, these crashes often happen at intersections and can result in serious injuries due to the limited protection on the sides of vehicles.

Common causes include:

  • Running red lights or stop signs
  • Failing to yield
  • Distracted or impaired driving

Fault usually falls on the driver who violated a traffic signal or right-of-way rule. Evidence like traffic camera footage or witness statements often plays a key role here.

Multi-Vehicle Pileups

Pileups are more common on highways and can involve several drivers in a chain reaction. These crashes can be chaotic and difficult to sort out.

Common causes include:

  • Sudden braking
  • Following too closely
  • Poor visibility due to weather or road conditions

These cases can be complicated. Multiple drivers may share responsibility, and investigators will look closely at who initiated the crash and how other drivers reacted.

Lane-Change and Merging Accidents

With heavy freeway traffic in San Bernardino County, unsafe lane changes happen more often than many drivers realize. Even a small miscalculation can lead to a collision.

Common causes include:

  • Failing to check blind spots
  • Not signaling
  • Aggressive or impatient driving

The driver changing lanes is generally responsible for making sure it’s safe to do so. If they collide with a vehicle already in the lane, they are often found at fault.

Distracted Driving Accidents

Distractions (especially smartphones) continue to be a leading cause of crashes. Even a momentary lapse in attention can have serious consequences.

Common causes include:

  • Texting or using apps while driving
  • Eating or adjusting in-car controls
  • Losing focus due to passengers or other distractions

A distracted driver who causes an accident is typically considered negligent. In some cases, phone records or other evidence may help prove distraction.

Drunk or Impaired Driving Crashes

Driving under the influence remains a serious issue throughout California and puts everyone on the road at risk.

Common causes include:

  • Alcohol or drug impairment
  • Slower reaction times
  • Poor decision-making

Drivers who are impaired are almost always held responsible for the accidents they cause. In certain situations, other parties may also share liability.

How Fault Is Determined

Determining fault isn’t always straightforward, especially when multiple drivers are involved. Insurance companies, attorneys, and sometimes courts rely on different types of evidence to piece together what happened.

Police Reports

After an accident, officers typically create a report documenting key details. This can include:

  • Statements from drivers and witnesses
  • Observations about the accident scene
  • Any citations or violations issued

While not the final word, these reports can be very influential in determining fault.

Witness Statements

Independent witnesses can offer valuable insight, especially when drivers remember events differently. Their perspective can help clarify how the accident unfolded.

Physical Evidence

Details like vehicle damage, skid marks, and road conditions can help reconstruct how the crash occurred and support one version of events over another.

Photos and Videos

Photos taken at the scene, dashcam footage, and nearby surveillance cameras can provide clear, objective evidence that strengthens a claim.

Traffic Laws

If a driver violates a traffic law, such as running a red light or speeding, that violation can be a strong indicator of fault and negligence.
