Can Both Drivers Be at Fault in a Sideswipe Collision?

Sideswipe accidents often happen quickly and without clear warning. Because both vehicles are typically moving when the collision occurs, determining who is responsible can be complicated. In many cases, more than one driver may share responsibility for the crash. A knowledgeable sideswipe car accident lawyer understands that fault in these accidents is not always black and white.
If you were involved in a sideswipe collision in California, it is important to understand how shared fault works and how it can affect your right to compensation.
Why Sideswipe Accidents Often Involve Shared Fault
Sideswipe collisions frequently occur when vehicles are traveling side-by-side in adjacent lanes. These crashes may happen when:
- Two drivers attempt to change lanes at the same time
- One driver drifts slightly while another merges without signaling
- A driver fails to check a blind spot while another driver speeds past
- Heavy traffic causes multiple vehicles to maneuver simultaneously
Because both drivers may be performing maneuvers at the time of the crash, investigators often examine whether each driver contributed to the accident.
A skilled sideswipe car accident lawyer carefully analyzes the movements of both vehicles to determine how the collision occurred.
California’s Comparative Negligence Law
California follows a pure comparative negligence system. This means that fault for an accident can be divided among multiple parties.
For example:
- Driver A may be 60 percent responsible for drifting into another lane
- Driver B may be 40 percent responsible for making an unsafe lane change
In this situation, each driver is responsible for damages according to their percentage of fault.
This system allows injured victims to recover compensation even if they are partially responsible for the accident.
How Shared Fault Affects Compensation
When fault is shared, compensation is reduced based on the injured party’s percentage of responsibility.
For example, if your damages total $100,000 but you are found to be 30 percent at fault, your recovery would be reduced by that percentage. You would still be eligible to receive $70,000.
Insurance companies often try to increase a victim’s percentage of fault to reduce the amount they must pay. A knowledgeable sideswipe car accident lawyer works to ensure that fault is assigned fairly.
Common Scenarios Where Both Drivers Share Responsibility
Several situations may lead investigators to assign fault to both drivers:
Simultaneous lane changes
Two drivers attempt to merge into the same lane at the same time.
Blind spot misunderstandings
One driver fails to check a blind spot while another driver remains in the blind spot longer than expected.
Aggressive driving
Speeding or weaving through traffic can increase the likelihood of sideswipe collisions.
Distracted driving
A driver who drifts slightly due to distraction may collide with another vehicle that was also maneuvering.
Evidence Used to Determine Fault
Because sideswipe accidents often involve conflicting stories, evidence plays a crucial role in determining liability. Important evidence may include:
- Police reports
- Witness statements
- Dashcam footage
- Traffic camera recordings
- Vehicle damage patterns
- Accident reconstruction analysis
Damage patterns on the vehicles can reveal how the impact occurred and which driver entered another lane.
Why Insurance Companies Dispute These Accidents
Sideswipe collisions are frequently disputed because the damage may appear minimal or because both drivers claim the other caused the crash.
Insurance companies often attempt to assign partial blame to reduce their payout. Without strong evidence, the case may turn into a word-against-word dispute.
A skilled sideswipe car accident lawyer investigates the accident thoroughly to establish an accurate account of events.
Injuries Can Still Be Serious
Even when fault is shared, sideswipe collisions can cause significant injuries such as:
- Whiplash
- Neck and back injuries
- Shoulder injuries
- Concussions
- Cuts from shattered glass
If the collision forces a vehicle off the road or into another lane, the accident can escalate into a more severe crash.
Compensation Available After a Sideswipe Accident
Injured victims may still recover compensation for:
- Medical expenses
- Lost wages
- Property damage
- Pain and suffering
- Future medical treatment
The amount recovered depends on the severity of injuries and each party’s percentage of fault.
