Intersection Accidents and Negligence Per Se

New York’s Vehicle & Traffic Law establishes clear right-of-way rules that govern every intersection in Nassau and Suffolk County. VTL §1111 requires obedience to traffic signals — a driver who enters an intersection after the signal has turned red is in direct violation of the statute. VTL §1140 governs vehicles approaching or entering an uncontrolled intersection. VTL §1141 requires a driver turning left to yield to all oncoming traffic and pedestrians in the intersection or close enough to constitute an immediate hazard. VTL §1142 requires a driver facing a stop sign to stop and yield the right of way to vehicles in or approaching the intersection. VTL §1143 imposes the same yield requirement on drivers facing a yield sign.

When a driver violates one of these statutes and causes an accident, they are negligent per se — the statutory violation is itself evidence of breach of the duty of care, removing the need to prove the standard of care separately. In practical terms, this means the liability dispute shifts away from “was the driver unreasonable” and toward damages and comparative fault. It is one of the most powerful legal doctrines available to intersection accident victims in New York civil courts, and our firm uses it aggressively. For a broader overview of how fault and insurance work across all types of motor vehicle collisions in New York, see our car accident lawyer page.

Nassau and Suffolk County have some of the highest intersection crash rates in New York, particularly on heavily traveled corridors. Hempstead Turnpike is one of the most dangerous roads in Nassau County, with numerous signalized intersections experiencing high crash frequencies. Sunrise Highway runs east-west through both counties and is a consistent site of serious intersection crashes. Route 110 in Amityville and Huntington sees heavy commercial and commuter traffic. Merrick Avenue in Nassau County, Route 25A across Suffolk County, and Old Country Road in Nassau County are also high-frequency corridors for intersection crashes. If you were injured at any of these locations — or at any Long Island intersection — the right-of-way analysis under New York’s VTL statutes applies.

How We Prove Fault at an Intersection

Proving fault at a Long Island intersection requires immediate, methodical evidence gathering. The at-fault driver almost always disputes liability — everyone claims they had the green light. The evidence we build in the days and weeks after the crash is what determines how the case resolves.

Traffic camera footage is the gold standard for intersection liability. Nassau County maintains an extensive traffic monitoring camera network at signalized intersections throughout the county. Suffolk County has cameras at many signalized intersections along major corridors. New York State Department of Transportation (NYSDOT) maintains cameras on state roads including Sunrise Highway and Route 110. This footage captures exactly what happened in the seconds before and during the crash — who had the green light, who ran the red, whether a vehicle slowed before the stop line, and how long the light had been red when the at-fault driver entered. We send preservation demands and FOIL requests to the relevant municipality or agency within days of being retained, because this footage is routinely overwritten within 30 days.

Dashcam footage from other vehicles traveling through or near the intersection at the time of the crash can capture the collision sequence. We send preservation letters to known dashcam owners and, where possible, conduct neighborhood canvas to identify vehicles with dashcam systems that may have been in the area. Business security cameras, ATM cameras, and residential doorbell cameras near the intersection often capture the crash or the seconds before it — we reach out to nearby businesses and property owners immediately.

Physical evidence analysis is critical when camera footage is unavailable. Skid marks — their direction, length, and relationship to the intersection lanes — establish pre-impact speed and braking behavior. Property damage geometry tells a precise story: the location of the impact on each vehicle, the angle of the crush, and the relative positions of both vehicles at the moment of impact tell us who was traveling in which direction and who entered the intersection without yielding. A T-bone impact on the driver’s side versus the passenger side, for example, indicates which direction each vehicle was traveling — information that directly informs the right-of-way analysis. The MV-104 police report records contributing factor codes assigned by the responding officer, including “Failure to Yield Right of Way,” “Ran Traffic Control Device,” and “Driver Inattention.” These codes are powerful corroborating evidence.

For seriously disputed liability cases, we retain qualified accident reconstruction engineers who apply engineering and physics principles to the physical evidence to produce expert opinions on pre-impact speed, point of impact, and vehicle trajectories that hold up under cross-examination at deposition and trial.

T-Bone Side-Impact Crashes: Why They’re So Dangerous

Side-impact collisions at intersections — commonly called T-bone crashes — are among the most dangerous type of car accident. When a driver runs a red light or stop sign and strikes a vehicle traveling through the intersection, the collision is nearly always a T-bone: one vehicle strikes the side of the other at or near a right angle. Unlike front-end and rear-end collisions, where the vehicle’s crumple zones and front/rear structural members absorb much of the impact energy, a vehicle’s side structure offers minimal protection. There is no crumple zone between the door panel and the occupant. Door panels are thin metal and glass. Side airbag coverage, while improved in modern vehicles, is limited compared to frontal airbag systems. The occupant on the struck side — the driver or passenger whose door absorbs the impact — is separated from the striking vehicle by only inches of door panel and window glass.

The injury patterns in T-bone crashes reflect this structural vulnerability. Traumatic brain injury (TBI) occurs when the door intrudes into the occupant compartment or when the occupant’s head strikes the window or door frame. Rib fractures and pneumothorax (collapsed lung) result from door intrusion and seatbelt forces. Splenic and liver lacerations are characteristic of high-energy lateral impact forces to the torso. Pelvis fractures and hip injuries occur when the door panel contacts the lower body. Shoulder injuries, including labral tears and rotator cuff damage, result from the arm braced against the door or armrest at impact. These injuries routinely satisfy the Insurance Law §5102(d) serious injury threshold, clearing the pathway to full recovery of non-economic damages.

Long Island’s major corridors create the conditions for high-speed T-bone crashes. Speed limits on roads like Sunrise Highway, Route 110, Hempstead Turnpike, and Route 25A range from 35 to 55 mph. A driver running a red light at 45 mph at one of these intersections strikes a crossing vehicle with enormous force. At these speeds, the kinetic energy transferred in a T-bone collision is catastrophic — the crash dynamics are closer to a high-speed highway collision than a low-speed parking lot incident. The intersection location means there is typically no warning, no evasive maneuver, and no braking before impact for the victim who had the right of way. The resulting injuries are disproportionately serious compared to the vehicle miles traveled at that intersection, and the damage awards in these cases reflect that reality.

What Damages Can You Recover?

Victims of intersection accidents on Long Island may recover two categories of damages in a personal injury lawsuit: economic damages and non-economic damages.

Economic damages cover measurable financial losses: past and future medical expenses (emergency room treatment, surgery, hospitalization, physical therapy, medication, medical devices, and projected future care); past and future lost wages and lost earning capacity; property damage to your vehicle; and out-of-pocket expenses related to the accident and recovery. Economic damages are calculated based on documented losses and credible expert projections of future costs.

Non-economic damages cover the human losses that cannot be reduced to a receipt: pain and suffering, physical disability, loss of enjoyment of life, emotional distress, and loss of consortium. These damages are not capped in New York personal injury cases, but they require the plaintiff to meet the serious injury threshold.

New York’s no-fault insurance system requires injury victims to first pursue Personal Injury Protection (PIP) benefits through their own no-fault carrier for medical expenses and lost wages, regardless of fault. A lawsuit against the at-fault driver for non-economic damages requires proof of a “serious injury” as defined by Insurance Law §5102(d). Qualifying categories include a fracture; significant disfigurement; 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; and the 90/180-day category (inability to perform substantially all customary daily activities for 90 of the first 180 days post-accident). T-bone intersection crashes — with their characteristic TBI, rib fractures, and orthopedic injuries — frequently produce injuries that satisfy multiple threshold categories simultaneously.

Intersection accidents may also involve municipal liability when the traffic signal at the intersection was malfunctioning, the signal timing was negligently programmed, or the intersection design created an unreasonably dangerous condition. Claims against municipalities — Nassau County, Suffolk County, the Town of Hempstead, NYSDOT, or any other government entity that owns or maintains the traffic control device — require a Notice of Claim filed within 90 days of the accident under General Municipal Law §50-e. This is a hard deadline: failure to file a timely Notice of Claim permanently bars your claim against the municipal defendant. Our firm evaluates municipal liability at the outset of every intersection accident case and files the Notice of Claim immediately when applicable.

Under CPLR §1411, New York’s comparative negligence rule, your recovery is reduced proportionally by your percentage of fault — but you are not barred from recovery even if you were partially at fault. The at-fault driver’s insurer will attempt to assign fault to you as a negotiating tactic. Our firm builds the evidence record to accurately reflect the true allocation of fault and resist inflated comparative fault arguments from the defense.
