Many people mistakenly believe that if only one vehicle was involved in a crash, the driver automatically has no legal claim. In reality, single-vehicle accidents are often caused by the negligence of someone other than the injured driver. Dangerous road conditions, defective vehicle components, negligent roadway maintenance, improperly secured commercial cargo, reckless drivers who leave the scene, and other hazards frequently contribute to crashes involving only one vehicle.
At Flynn Law, our experienced single-vehicle accident lawyers help injured clients throughout New Jersey, Pennsylvania, Delaware, and New York determine exactly what caused their accident and who should be held responsible. Whether your crash occurred in Wilmington, Philadelphia, Camden, Manhattan, Brooklyn, Queens, the Bronx, Staten Island, or another community within our four-state service area, our legal team is prepared to investigate every possible source of liability and pursue the compensation you deserve.
What Is a Single-Vehicle Accident?
A single-vehicle accident involves only one vehicle making physical contact with another object or leaving the roadway. Although another automobile may not actually collide with the victim’s vehicle, another person’s negligence may still have caused the crash.
Examples include:
- Running off the roadway
- Striking a guardrail
- Hitting a utility pole
- Colliding with a tree
- Crashing into a concrete barrier
- Entering a ditch
- Rolling over
- Striking roadway debris
- Hitting an animal after avoiding another vehicle
- Avoiding a reckless driver who leaves the scene
Many of these accidents involve circumstances that are far more complicated than they initially appear.
Common Causes of Single-Vehicle Accidents
Single-vehicle crashes can occur for numerous reasons, many of which involve negligence by another individual, company, or governmental entity.
Common causes include:
- Dangerous roadway defects
- Large potholes
- Uneven pavement
- Missing guardrails
- Poor roadway design
- Inadequate drainage
- Hydroplaning
- Ice and snow
- Fallen trees
- Construction zone hazards
- Poor lighting
- Missing traffic signs
- Defective traffic signals
- Tire blowouts
- Brake failures
- Steering failures
- Suspension failures
- Mechanical defects
- Tire tread separation
- Cargo falling from commercial vehicles
- Animals entering the roadway
- Drivers forcing another vehicle off the road
- Fatigued or distracted driving
Each of these situations requires careful investigation to determine whether another party’s negligence contributed to the accident.
Not Every Single-Vehicle Accident Is the Driver’s Fault
Insurance companies often assume that the driver of the only vehicle involved must have caused the collision. However, that assumption is frequently incorrect.
Examples where another party may be responsible include:
- A tractor-trailer loses cargo that blocks the roadway.
- A municipality fails to repair a dangerous pothole despite repeated complaints.
- A vehicle manufacturer produces defective brakes that suddenly fail.
- A negligent driver forces another vehicle off the road without making contact.
- A construction company creates an unsafe roadway condition.
- A tire manufacturer produces a defective tire that experiences catastrophic tread separation.
These situations may give rise to claims against commercial businesses, governmental agencies, manufacturers, contractors, or other negligent parties.
Roadway Defects Can Cause Serious Accidents
Poorly maintained roads contribute to thousands of crashes every year.
Dangerous roadway conditions include:
- Deep potholes
- Uneven pavement
- Missing lane markings
- Poor drainage
- Flooded roadways
- Broken traffic signals
- Missing warning signs
- Damaged guardrails
- Unsafe construction zones
- Improper road design
- Shoulder drop-offs
- Debris left on roadways
Government agencies responsible for roadway maintenance may, under certain circumstances, be held accountable for injuries resulting from dangerous road conditions. These claims often involve special notice requirements and shorter legal deadlines, making prompt legal representation especially important.
Vehicle Defects May Lead to Single-Vehicle Crashes
Mechanical failures sometimes occur without warning despite proper vehicle maintenance.
Potential defects include:
- Brake failures
- Steering system failures
- Tire defects
- Tire tread separation
- Suspension failures
- Accelerator defects
- Airbag failures
- Electronic stability control failures
- Defective seat belts
Product liability claims often require engineering analysis and preservation of the vehicle before repairs or disposal destroy important evidence.
Commercial Vehicles Can Cause Single-Vehicle Accidents Without Impact
Not every accident involving a commercial truck requires physical contact between vehicles.
For example:
- A truck loses construction materials onto the highway.
- Cargo shifts and spills into traffic.
- A delivery vehicle suddenly changes lanes, forcing another driver off the road.
- A commercial vehicle creates dangerous debris that causes another driver to crash.
In many of these situations, the injured driver may still have a valid claim despite there being no direct collision.
Common Injuries Following Single-Vehicle Accidents
Because many single-vehicle crashes involve striking fixed objects or rolling over, injuries are often severe.
Common injuries include:
- Traumatic brain injuries (TBIs)
- Concussions
- Skull fractures
- Neck injuries
- Back injuries
- Herniated discs
- Spinal cord injuries
- Paralysis
- Broken bones
- Pelvic fractures
- Internal bleeding
- Facial injuries
- Burns
- Crush injuries
- Amputations
- Severe lacerations
- Psychological trauma
- Post-traumatic stress disorder (PTSD)
Victims frequently require extensive emergency treatment, surgery, rehabilitation, and ongoing medical care.
Rollover Crashes Often Occur During Single-Vehicle Accidents
Many rollover accidents begin as single-vehicle crashes.
A driver may:
- Leave the roadway
- Strike a curb
- Hit a guardrail
- Overcorrect the steering wheel
- Encounter a soft shoulder
- Trip on uneven pavement
Once a vehicle begins to roll, occupants face significantly increased risks of catastrophic injuries, particularly if they are not properly restrained or if the vehicle experiences roof crush.
Investigating a Single-Vehicle Accident
Thorough investigation is essential because liability may not be immediately apparent.
Important evidence often includes:
- Police reports
- Scene photographs
- Vehicle inspections
- Event data recorder downloads
- Tire inspections
- Mechanical evaluations
- Roadway engineering reports
- Weather data
- Maintenance records
- Construction records
- Surveillance footage
- Witness statements
- Expert accident reconstruction
At Flynn Law, we move quickly to preserve this evidence before it disappears or is altered, helping build the strongest possible claim on behalf of our clients.
