Out to 25 miles, the count of graded towns reaches 7. Dillon Beach has no police department of its own: it’s an unincorporated community (a census-designated place) in Marin County. The Marin County Sheriff’s Office reports to the FBI for the parts of the county without police of their own, so there are no figures for Dillon Beach alone, and no Safety Grade. The closest graded town is Sebastopol, 13 miles away, at C.

No one died in a crash on Dillon Beach’s roads in 2019–2023
That is about what is typical for California towns of 2,500–5,000 people: at their median rate (7.0 deaths per 100,000 residents a year), a town of Dillon Beach’s size would see about 0 in five years. With numbers this small, a death or two either way changes the picture, so Dillon Beach’s own rate (0.0) 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.
