One dead, three seriously injured in head-on crash on Long Island: police

Call 911 immediately if anyone is injured or if the vehicles can't be moved safely off the roadway. Stay at the scene — leaving the scene of an accident with injuries is a crime under New York Vehicle and Traffic Law §600. Exchange license, registration, and insurance information with every other driver involved. Take photographs of every vehicle, the position of the vehicles before they're moved, all license plates, the road surface, traffic signs, and any visible injuries. Get the names and phone numbers of every witness — police often won't capture bystander witnesses on their own. Seek medical attention within 24 hours even if you feel fine; soft-tissue injuries and concussions can take a day or two to present, and a delayed medical visit weakens an injury claim. In Nassau County, NCPD responds outside of incorporated villages. In Suffolk County, SCPD covers the five western towns; East End towns have their own forces. New York State Police Troop L responds to accidents on state highways across both counties.

Thirty days. New York Insurance Law §5102 requires you to file a Personal Injury Protection (PIP/no-fault) application with the insurer of the vehicle you were in (or, if you were a pedestrian or cyclist, with the insurer of the striking vehicle) within 30 days of the accident. Missing the 30-day deadline can void your no-fault benefits — that's up to $50,000 in medical bills and 80% of lost wages (capped at $2,000/month) per injured person. The form is the NF-2 application; your insurance carrier provides it on request. New York no-fault is a true PIP system: it pays regardless of who caused the crash.

Under Insurance Law §5102(d), a "serious injury" is one that meets at least one of these categories: (1) death; (2) dismemberment; (3) significant disfigurement; (4) a fracture; (5) loss of a fetus; (6) permanent loss of use of a body organ, member, function, or system; (7) permanent consequential limitation of use of a body organ or member; (8) significant limitation of use of a body function or system; or (9) a medically determined injury that prevents the injured person from performing substantially all daily activities for at least 90 of the first 180 days following the accident. Only injuries that meet one of these nine categories create the right to sue the at-fault driver for pain and suffering damages — short of that threshold, recovery is limited to no-fault PIP benefits. Disputes over whether an injury meets the threshold are the single most-litigated issue in NY motor-vehicle cases.
