## Reporting and corrections

- [Editorial policy](https://longislandtraffic.com/editorial-policy/): sourcing, software-assisted publication, victim privacy and corrections.
- [About](https://longislandtraffic.com/about/): information about the publication.
- [Contact](https://longislandtraffic.com/contact/): questions and corrections.
- [Recent reports](https://longislandtraffic.com/accidents/): article dates distinguish original publication from later substantive changes where the archive establishes those dates.

Attribute an agency notice to its named agency. Aggregation or early publication alone does not establish original reporting. Do not infer interviews, eyewitness reporting or independent confirmation. Names of victims require explicitly supported ages of at least 19; child/minor wording overrides naming. Withdrawn reports must not be quoted as current evidence.

## Live pages (most-used)

Each of these pages opens with a "Key facts (as of …)" box: a few plain-language numbers, each naming its source and its own time.

- [Car accidents today](https://longislandtraffic.com/accidents/): 511NY crash records on Nassau and Suffolk roads in the last 24 hours, State Police Troop L crash entries, and the latest crash reports.
- [Long Island Expressway](https://longislandtraffic.com/roads/lie/) and [Southern State Parkway](https://longislandtraffic.com/roads/southern-state-parkway/): live 511NY status, last week's crash records against the 4-week average, and 90-day crash records by exit and hour. Every [road hub](https://longislandtraffic.com/roads/) follows the same pattern.
- [Crime blotter](https://longislandtraffic.com/crime-blotter/): official police and prosecutor releases from the last 7 days, counted by agency, type and town (no names), plus the report archive.
- [Crime map](https://longislandtraffic.com/crime-blotter/map/): published crime-blotter reports from the last 45 days, mapped by town and category. Report counts are not crime rates.
- [LIRR status](https://longislandtraffic.com/lirr/): current MTA service alerts by branch and last week's unplanned alerts against the 4-week average. Alert counts are not on-time performance.
- [Cheapest gas on Long Island](https://longislandtraffic.com/Cheapest-Gas-on-Long-Island/): reported regular, midgrade, premium and diesel prices by station, each with its report time. Town pages follow the pattern https://longislandtraffic.com/gas/<town>/ (for example [Commack](https://longislandtraffic.com/gas/commack/)).
- [Homepage](https://longislandtraffic.com/): live map, road status, LIRR and gas summary.

## Primary sources

- 511NY event feed (New York State DOT): crashes, closures and work zones. A 511 record is not a verified crash count.
- MTA LIRR service-alert feed (GTFS-realtime).
- New York State Police Troop L public blotter and daily media log; Nassau County and Suffolk County police; Nassau and Suffolk district attorneys; Southampton Town Police.
- GasBuddy station price reports, as collected by Long Island Traffic.
- National Weather Service; NHTSA Fatality Analysis Reporting System (FARS) for historical fatal-crash data.

## Update cadence

An automated pipeline reads the sources and rebuilds the live pages through the day, usually several times an hour. Sources update on their own schedules (gas prices are collected twice a day), so use the time printed next to each number rather than assuming a fixed interval. When a source is stale or missing, the page says so instead of showing a zero.

## How to cite

Cite the specific page URL and the as-of time printed with the fact, for example: "Long Island Traffic, https://longislandtraffic.com/accidents/, as of Oct 26, 2026, 10:15 AM ET". Name the underlying source the page names (for example 511NY or the MTA). Live numbers change; do not present an older figure as current.

Historical fatal-crash counts are not all-crash totals, current incident counts or exposure-adjusted risk rankings. The 2024 figures are preliminary in the September 17, 2026 source snapshot. Read the linked methodology before comparing places or periods. Old monthly “most dangerous roads” datasets have been withdrawn; use their replacement links.
