Who polices Triangle, and what they report
Triangle has no police department of its own: it’s an unincorporated community (a census-designated place) in Prince William County. The Prince William County Police Department reports to the FBI for the parts of the county without police of their own, so there are no figures for Triangle alone, and no Safety Grade.

Six people died in crashes on Triangle’s roads in 2019–2023
Triangle had 6 fatal crashes in five years, in which six people died; 3 were pedestrians.
That is more than is typical for Virginia towns of 5,000–25,000 people: at their median rate (3.9 deaths per 100,000 residents a year), a town of Triangle’s size would see about 2 in five years. With numbers this small, a death or two either way changes the picture, so Triangle’s own rate (11.5) is context, not a ranking.
Deaths are counted where the crash happened, not where the people lived: a highway through town adds through-traffic deaths, and residents’ own risk on roads elsewhere isn’t here. Town rates sit below state and U.S. rates because a third of fatal crashes happen outside any town. Road safety is described here and is not part of the Safety Grade.

What this data can and can’t tell you
- It’s reported crime. Only incidents reported to and recorded by police appear here. Many crimes are never reported to police.
- A county agency covers a wide area. Its totals mix many communities, so they say little about any one of them.
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
