Questions

Montgomery County, MD — FAQ

Where does the Montgomery County, MD crash data come from?
Directly from official government open data: dataMontgomery — Crash Reporting: Incidents Data (MCPD / ACRS). Police-reported collisions are published on the open-data portal (typically with a short processing delay) and we re-read it every 6 hours. This is real police data, not news reports.
How many car accidents happen in Montgomery County, MD?
In this latest sample of 150 police-reported crashes (2026-09-30 to 2026-10-07), 49 people were injured and 1 killed. Across the whole area, Montgomery County, MD records thousands of reported collisions per year.
Is this map real-time?
No, but it is recent: police publish crash records to the open-data portal after a short processing delay (the newest record here is from 2026-10-07), and we re-read it every 6 hours. For life-threatening emergencies always call 911 — this page is informational.
What can the crash pattern explorer show?
It filters the official records from the last 365 days (up to 5,000 of the most recent) by period, severity, collision type and a circle drawn on the map, and charts them by week, weekday and hour next to a full-year monthly total from the portal's own counts. It counts recorded crashes only: without traffic volumes it cannot say how risky a street is, so it never ranks streets as safe or dangerous.
