Getting sideswiped on the highway or during a lane change can happen in seconds, but the aftermath often raises complicated questions about insurance, injuries, and whether you have grounds to file a lawsuit. In New York, the answer isn't always straightforward because of the state's no-fault insurance system and specific thresholds you need to meet before taking legal action.
If another driver clipped your vehicle while merging, drifted into your lane, or failed to check their blind spot, you might be dealing with more than just car repairs. Sideswipe collisions can cause serious injuries, from whiplash and concussions to fractured bones and long-term back problems. Understanding when you can sue and what legal hurdles you'll face is essential to protecting your rights and getting the compensation you deserve.
This article explains the legal landscape around sideswipe collisions in New York, including how fault gets determined, what injuries qualify for a lawsuit, and the practical steps you should take after a crash.
Can You Sue for a Sideswipe Collision in New York
The short answer is yes, you can potentially sue after a sideswipe collision in New York, but whether you're legally allowed to file a lawsuit depends on several factors that make these cases more complicated than in other states. New York's no-fault insurance system creates barriers that don't exist in most of the country, and understanding these restrictions is the first step in figuring out whether you have a viable case.
The key issue is that New York law doesn't automatically give you the right to sue another driver just because they caused an accident. You need to clear specific legal hurdles related to how badly you were injured and whether those injuries meet statutory definitions that allow you to step outside the no-fault system. This means two people could be in very similar sideswipe collisions with the same type of negligent driver, but only one might have grounds for a lawsuit depending on the nature and severity of their injuries.
Whether a lawsuit makes sense also depends on who was at fault and how clearly you can prove negligence. If the other driver obviously violated traffic laws by making an unsafe lane change, failed to check their blind spot before merging, or drifted into your lane due to distraction or impairment, you have stronger grounds for legal action. The strength of your evidence matters just as much as the severity of your injuries. Even serious injuries won't support a successful lawsuit if you can't establish that the other driver's negligence caused the collision.
The practical reality is that many sideswipe collisions result in minor injuries that heal within weeks and don't come close to meeting New York's serious injury threshold. These cases get resolved through insurance claims without any lawsuit, and that's often the right outcome. But when a sideswipe causes documented serious injuries like fractures, significant disc herniations, or trauma that prevents you from working and living normally for months, you shouldn't assume that insurance benefits are your only option.
What Exactly Is a Sideswipe Collision?
A sideswipe collision happens when the sides of two vehicles make contact while traveling in the same or opposite directions. These crashes typically occur during lane changes, when a driver drifts out of their lane without realizing it, or when someone misjudges the space between vehicles on multi-lane roads.
National Highway Traffic Safety Administration research suggests that many sideswipe incidents happen at moderate highway speeds when drivers execute lane changes without adequately checking mirrors or blind spots. These aren't always low-impact fender benders. Depending on speed, road conditions, and vehicle size, sideswipe collisions can cause significant damage and injuries that affect victims for months or even permanently.
The mechanics of these crashes matter because they often leave clear evidence about who violated traffic laws. Paint transfer, scrape patterns, and the location of vehicle damage can help reconstruct exactly what happened in those critical seconds before impact.
Who Is Actually at Fault in a Sideswipe Crash?
Figuring out fault in a sideswipe collision comes down to which driver violated their duty to operate their vehicle safely. New York Vehicle and Traffic Law Section 1128(a) requires drivers to stay "as nearly as practicable entirely within a single lane" and prohibits moving from that lane "until the driver has first ascertained that such movement can be made with safety."
This statute creates a clear legal standard. If you changed lanes without making sure it was safe to do so, you've likely violated this law. Common scenarios where drivers breach this duty include failing to signal before changing lanes, not checking blind spots, drifting due to distraction or fatigue, speeding that makes lane control difficult, or misjudging the speed and distance of vehicles in adjacent lanes.
Violating a traffic safety statute like Section 1128 can serve as powerful evidence of negligence in a civil lawsuit. It shows the other driver had a specific legal duty, broke that duty, and the violation directly led to the collision.
Does Shared Fault Mean I Can't Sue?
New York follows a pure comparative negligence rule, which fundamentally affects every car accident case in the state. Under this system, even if you share some responsibility for the crash, you can still recover damages. Your compensation just gets reduced by your percentage of fault.
Imagine a sideswipe where both drivers were attempting to merge into the same center lane at roughly the same time. A jury might determine one driver was 60% at fault for failing to check their blind spot, while the other was 40% at fault for not using a turn signal. If the less-at-fault driver had $100,000 in damages, they would recover $60,000 (reduced by their 40% share of responsibility).
This matters because insurance companies and defense attorneys will try to shift as much blame as possible onto you to reduce what they have to pay. Having a clear picture of what actually happened, supported by evidence like dashcam footage, witness statements, and police reports documenting traffic violations, becomes critical to protecting your claim.
Unlike some states that bar recovery if you're more than 50% at fault, New York allows you to collect damages even if you were mostly responsible. You just can't recover anything if you're found 100% at fault.
How New York's No-Fault Insurance System Affects Your Ability to Sue
New York operates under a no-fault auto insurance system, which changes the basic rules about when you can sue after a car accident. After most crashes, including sideswipe collisions, each injured person turns first to their own Personal Injury Protection coverage for medical expenses and a portion of lost wages, regardless of who caused the accident.
This system was designed to reduce litigation over minor accidents and speed up payment of basic expenses. Your PIP coverage generally provides up to $50,000 per person in what the law calls "basic economic loss." This includes reasonable medical bills, 80% of lost earnings up to certain limits, and other out-of-pocket costs directly tied to your injuries.
For many sideswipe crashes that cause soft-tissue strains, brief medical treatment, and quick recovery, no-fault benefits end up being the only realistic source of compensation. You get your medical bills paid and recover some lost wages without needing to prove anyone was negligent or file a lawsuit.
The tradeoff is significant, though. In exchange for this guaranteed coverage from your own insurer, you generally cannot sue the at-fault driver for additional damages unless you clear specific legal thresholds.
When Can You Step Outside the No-Fault System?
To file a lawsuit seeking pain and suffering damages and other compensation beyond basic no-fault benefits, you must prove either that your basic economic loss exceeds $50,000, or that you suffered a "serious injury" as defined by New York Insurance Law Section 5102(d).
The serious injury threshold includes nine specific categories:
- Death
- Dismemberment
- Significant disfigurement
- Any bone fracture
- Loss of a fetus
- Permanent loss of use of a body organ or member
- Permanent consequential limitation of use of a body organ or member
- Significant limitation of use of a body function or system
- A medically determined non-permanent injury that prevents you from performing substantially all of your usual daily activities for at least 90 of the 180 days immediately following the accident
Courts interpret these categories strictly, particularly the "significant limitation" language. New York judges consistently hold that minor or mild limitations don't meet the statutory threshold. You need objective medical evidence documenting the nature and extent of your injuries.
What Kind of Medical Proof Do You Actually Need?
Meeting the serious injury threshold requires more than just saying you're in pain or that your daily life has been affected. New York courts look for objective, quantifiable medical evidence that establishes the severity and duration of your limitations.
This typically includes diagnostic imaging like MRI or CT scans showing structural damage, range-of-motion measurements documented by your treating physicians over time, specialist evaluations from orthopedists, neurologists, or other relevant experts, detailed medical records showing consistent treatment and therapy, and documentation of how specific physical limitations prevented you from working or performing normal daily activities.
The 90-out-of-180-days category requires particularly careful documentation. You need to show that your injuries were so severe that you couldn't perform substantially all of the activities that made up your usual daily routine for at least three months out of the first six months after the accident. This doesn't mean you were completely bedridden, but the limitations must have been substantial and well-documented.
Can Sideswipe Collisions Cause Serious Injuries?
Many people assume sideswipe crashes are minor because vehicles are traveling in roughly the same direction. That assumption can be dangerously wrong. While some sideswipe collisions cause only soft-tissue injuries that heal within weeks, others result in significant trauma.
Fractures are common in sideswipe crashes, particularly to arms, wrists, and ribs on the impact side. A fractured bone automatically qualifies as a serious injury under New York law, opening the door to a lawsuit regardless of how long recovery takes. Head injuries, including concussions and traumatic brain injuries, can occur when a driver's head strikes the window or when the sudden jolt causes the brain to move violently inside the skull.
Neck and back injuries from the sideways force and sudden jerking motion can produce herniated discs, torn ligaments, and muscle damage that creates long-term pain and mobility restrictions. When properly documented with MRI findings and specialist evaluations showing significant functional limitations, these injuries can meet the serious injury threshold.
Shoulder injuries are particularly common in side-impact crashes. The force can tear rotator cuffs or damage other shoulder structures, potentially causing permanent limitation of use. Even psychological trauma can matter if the crash triggers post-traumatic stress disorder that substantially limits your daily functioning, though this typically requires expert psychiatric evaluation and documentation.
The key point is that sideswipe collisions shouldn't be dismissed as automatically minor. The specific circumstances of your crash and the injuries you sustained determine whether you have grounds for a lawsuit.
What Elements Do You Need to Prove in a Negligence Case?
If you clear the no-fault thresholds and decide to sue, you'll need to establish four elements of negligence.
First, the other driver owed you a duty of reasonable care, which includes following traffic laws like the requirement to stay in your lane and only change lanes when safe. This duty exists automatically between all drivers sharing the road.
Second, the driver breached that duty through some form of careless or reckless conduct. In sideswipe cases, this often means changing lanes without checking blind spots, drifting due to distraction or drowsiness, failing to signal, driving too fast to maintain lane control, or violating Vehicle and Traffic Law Section 1128.
Third, the breach directly caused the collision and your injuries. You need to show a clear causal connection between what the other driver did wrong and the harm you suffered. This is usually straightforward in sideswipe cases where the point of impact and resulting injuries are directly linked to the improper lane change or drift.
Fourth, you suffered legally compensable damages. This includes your medical expenses, lost wages, property damage, and if you meet the serious injury threshold, pain and suffering, loss of enjoyment of life, and other non-economic harms.
How Long Do You Have to File a Lawsuit?
New York's statute of limitations for personal injury claims from car accidents, including sideswipe collisions, gives you three years from the date of the accident to file a lawsuit. Miss this deadline, and courts will dismiss your case regardless of how strong your claim is or how badly you were injured.
Three years may sound like plenty of time, but it passes faster than you'd expect, especially when you're focused on medical treatment and recovery. Important evidence can disappear, witnesses' memories fade, and insurance companies become less willing to negotiate as the deadline approaches.
Shorter deadlines may apply if your sideswipe involved a government vehicle or occurred due to a defective roadway maintained by a municipality. Claims against government entities in New York often require filing a notice of claim within just 90 days of the accident. If a city bus, sanitation truck, police car, or other municipal vehicle was involved, you need to act immediately to preserve your rights.
Even if you're still treating for your injuries or aren't sure yet whether you'll meet the serious injury threshold, it's worth consulting an attorney well before the statute of limitations expires. Some aspects of your case, like preserving evidence and documenting the full extent of your injuries, are much easier to handle closer to the accident date.
What Should You Do Right After a Sideswipe Collision?
The steps you take immediately after a sideswipe crash can significantly affect both your health and your legal options down the road.
Seek medical evaluation promptly, even if you feel fine. Many serious injuries, particularly to the neck, back, and head, don't cause immediate symptoms. Having a medical record created close to the accident date establishes the connection between the crash and your injuries.
Document everything you can at the scene if you're physically able. Take photos of vehicle positions, damage to both cars, skid marks, and road conditions. Get contact information from witnesses who saw the collision happen. Exchange insurance information with the other driver and request a police report.
Notify your insurance company right away. New York's no-fault system has strict time limits for submitting claims, and delays can result in denial of PIP benefits you're entitled to receive. Your insurer needs to know about the accident regardless of whether you plan to file a lawsuit later.
Keep detailed records of everything related to the accident and your injuries. Save all medical bills and treatment records, document missed work days and lost income, take notes on how your injuries affect your daily activities, and photograph visible injuries as they develop and heal. This documentation becomes crucial if you need to prove you meet the serious injury threshold.
Follow all medical advice and attend every scheduled treatment appointment. Gaps in treatment give insurance companies ammunition to argue your injuries weren't serious or that you failed to mitigate your damages. If you're not following your doctor's recommendations, juries may question whether you were really as injured as you claim.
Do Most Sideswipe Cases Settle or Go to Trial?
The vast majority of personal injury cases, including those arising from sideswipe collisions, settle before trial. Insurance companies know that going to court is expensive, time-consuming, and unpredictable. If you have strong evidence of the other driver's fault and clear medical documentation of serious injuries, the economics usually favor negotiating a settlement.
Settlement gives both sides control over the outcome and allows you to receive compensation faster than going through a trial. However, insurance companies also know that many accident victims are eager to resolve their claims quickly, especially if they're struggling financially due to lost wages and mounting medical bills. This can lead to lowball settlement offers that don't fully compensate you for your injuries and losses.
Having an experienced attorney who understands New York's no-fault system and serious injury threshold makes a significant difference in settlement negotiations. Insurance adjusters treat represented claimants differently because they know a lawyer can credibly threaten to take the case to trial if the offer isn't fair.
Some cases do need to go to trial, particularly when there's a genuine dispute about fault or whether injuries meet the serious injury threshold. If the insurance company refuses to make a reasonable offer, being prepared to let a jury decide can be the only way to get just compensation.
Understanding What Makes Your Case Different
National statistics show that sideswipe collisions represent a meaningful portion of serious traffic crashes. Data from the National Highway Traffic Safety Administration and insurance industry analyses suggest roughly 242,000 sideswipe crashes occur annually across the United States, resulting in approximately 2,500 deaths and 27,000 injuries. While sideswipe collisions account for a relatively small percentage of fatal crashes compared to head-on or intersection accidents, the numbers make clear these incidents are far from trivial.
Side-impact crashes more broadly represent about 28 to 30 percent of injured occupants and fatalities in passenger vehicles. The forces involved in side impacts, even glancing ones, can cause serious harm because vehicles have less protective structure on their sides compared to front and rear crumple zones.
These statistics matter for your case because they demonstrate to insurance companies and juries that sideswipe collisions can and do cause serious injuries. The narrative that these crashes are always minor doesn't hold up against the evidence.
When You Likely Can Sue After a Sideswipe in New York
You have grounds for a lawsuit beyond no-fault benefits when several conditions align. The other driver violated traffic laws or their duty of care by changing lanes unsafely, drifting due to distraction or impairment, or otherwise driving negligently. You suffered injuries that either exceeded $50,000 in basic economic loss or meet one of the nine categories of serious injury defined in state law. You have objective medical evidence documenting the severity and impact of your injuries. You're within the three-year statute of limitations, and even if you share some fault for the accident, your percentage of responsibility doesn't eliminate the other driver's liability under New York's comparative negligence rule.
Many minor sideswipe collisions with property damage and brief soft-tissue discomfort get handled entirely through insurance without any lawsuit. The no-fault system works reasonably well for these situations. But when a sideswipe causes broken bones, documented herniated discs with significant functional limitations, concussions or other traumatic brain injuries, or any injury that prevents you from performing your normal activities for months, you shouldn't assume insurance benefits are your only option.

Summing It Up
Whether you can sue after a sideswipe collision in New York depends on the severity of your injuries, the strength of your evidence about fault, and whether you meet specific legal thresholds built into the state's no-fault insurance system. Not every sideswipe crash leads to a lawsuit, nor should it. But serious injuries that meet statutory definitions or exceed economic loss limits open the door to seeking full compensation through the legal system.
The other driver's violation of lane-control laws, combined with objective medical proof of significant limitations from your injuries, creates the foundation for a strong negligence claim. New York's comparative negligence rule means you can still recover damages even if you share some responsibility for what happened.
If you've been injured in a sideswipe collision, focus first on your medical care and documenting both the crash and your injuries. The decisions about whether to pursue a lawsuit can come later, but the evidence you preserve and the treatment you receive now will determine what legal options remain available to you.
