ToggleLeft-turn collisions are among the most common types of car accidents, often leading to disputes over fault. You might be asking: Who is at fault in a left-turn collision car accident in Pennsylvania?
In Pennsylvania, the driver making a left turn is usually considered at fault in a left-turn collision unless evidence proves otherwise. State law requires left-turning drivers to yield to oncoming traffic, meaning they are generally presumed liable for the crash.
With decades of experience handling car accident claims in Pennsylvania, I’ve helped clients navigate fault disputes and secure fair compensation. Let’s explore the legal principles behind left-turn accidents and when exceptions to liability may apply.
What Do Pennsylvania Traffic Laws Say About Left-Turn Collisions?
Pennsylvania law requires drivers making a left-hand turn to yield the right of way to oncoming traffic unless they have a green arrow signal. According to Title 75 of the Pennsylvania Consolidated Statutes, the driver making the left turn is presumed to be at fault in a collision unless evidence shows otherwise. However, comparative negligence rules allow both parties to share fault based on their actions.
Key points:
- Left-turning drivers must yield unless they have the right of way.
- Failure to yield often results in the left-turning driver being held liable.
- Comparative negligence can reduce or share fault if the oncoming driver was speeding or ran a red light.

What Are Common Causes of Left-Turn Accidents in Pennsylvania?
Several factors can lead to left-turn collisions, often stemming from driver negligence or environmental conditions. Understanding these causes can help establish fault and strengthen your claim.
Common causes include:
- Distracted Driving: Texting, talking on the phone, or other distractions lead to delayed reactions.
- Speeding: Oncoming drivers exceeding speed limits can cause severe collisions.
- Impaired Driving: Drivers under the influence of alcohol or drugs often misjudge timing and distance.
- Running Red Lights: Oncoming drivers who run red lights increase the risk of collision.
- Weather Conditions: Poor visibility or wet roads can make it harder for drivers to see or stop in time.
Why Are Left-Turn Collisions More Dangerous?
Left-turn accidents are among the most dangerous types of collisions due to the angle and force of impact.
Key reasons:
- T-Bone Collisions: Oncoming vehicles often strike the side of the left-turning car, leading to severe injuries for occupants.
- High Speeds: Oncoming drivers traveling at high speeds can cause catastrophic damage.
- Vulnerable Passengers: The side impact often affects passengers directly, increasing injury severity.
- Common Injuries: Whiplash, fractures, spinal cord injuries, and traumatic brain injuries are prevalent in left-turn accidents.
How Is Fault Determined in a Left-Turn Collision?
Determining fault in a left-turn collision depends on evaluating the actions of both drivers and any extenuating circumstances.
Key factors include:
- Traffic Laws: Pennsylvania law requires left-turning drivers to yield to oncoming traffic, making them liable in most cases.
- Right-of-Way Violations: Oncoming drivers who violate traffic laws (e.g., speeding or running a red light) can share or bear fault.
- Eyewitness Testimonies: Neutral third-party accounts can clarify fault.
- Video Evidence: Traffic camera footage can provide an unbiased perspective on the collision.
Can Fault in a Left-Turn Collision Be Challenged in Pennsylvania?
While the left-turning driver is usually presumed at fault, there are circumstances where fault can be shared or shifted to the oncoming driver.
When fault can be challenged:
- Oncoming Driver’s Speeding: Evidence of excessive speed can shift liability.
- Running a Red Light: If the oncoming driver violated traffic signals, they may share or bear full fault.
- Distraction or Impairment: Proof that the oncoming driver was texting or under the influence can reduce the left-turn driver’s liability.
- Sudden Stop by Oncoming Driver: Abrupt stops by the oncoming driver may contribute to the accident.
Strong evidence, such as traffic camera footage or witness statements, can help challenge fault presumptions.

What Evidence Can Help Prove Fault in a Left-Turn Collision?
Gathering strong evidence is critical for proving liability. Key types of evidence include:
- Police Reports: Official documentation of the crash details and preliminary fault assessment.
- Dashcam Footage: Videos showing the events leading up to and during the collision.
- Witness Statements: Testimonies from bystanders who observed the accident.
- Photos of the Scene: Images showing vehicle damage, skid marks, and the intersection layout.
This evidence can strengthen your case, whether you’re negotiating with insurers or filing a lawsuit.
What Are Pennsylvania’s Comparative Negligence Laws?
Pennsylvania applies a modified comparative negligence rule under Title 42, Section 7102 of the Pennsylvania Consolidated Statutes. This means you can recover damages even if you share some fault for an accident, provided your fault does not exceed 50%. However, your compensation will be reduced by the percentage of fault assigned to you.
Example: If you are found 20% at fault for a car accident and awarded $100,000, your compensation would be reduced by 20%, leaving you with $80,000.
Can Road Conditions Affect Fault in Left-Turn Collisions?
Yes, poor road conditions can complicate fault determination. Examples include:
- Blocked View: Construction equipment or signage obscuring visibility.
- Malfunctioning Traffic Signals: A broken light can create confusion over right-of-way.
- Weather Hazards: Slippery roads or low visibility due to fog or rain.
In such cases, liability may be shared or attributed to third parties, such as government agencies responsible for road maintenance.

What Damages Can Be Recovered in a Left-Turn Collision?
Victims of left-turn collisions can recover economic damages like medical expenses, lost wages, and vehicle repair costs, as well as non-economic damages such as pain and suffering, emotional distress, and loss of enjoyment of life.
Types of Recoverable Damages:
- Economic Damages:
- Medical Expenses: Includes current treatment costs, future medical needs, and rehabilitation expenses.
- Lost Wages: Compensation for income lost due to inability to work.
- Vehicle Repair or Replacement Costs: Covers damage to your car resulting from the collision.
- Non-Economic Damages:
- Pain and Suffering: Reflects physical pain and its impact on daily life.
- Emotional Distress: Accounts for psychological trauma caused by the accident.
- Loss of Enjoyment of Life: Compensation for reduced quality of life due to injuries.
