The county's crashes, entered from the Patrol's own tables.

A ledger is only as honest as its sources. This one has a single source for every crash number it prints: the Missouri State Highway Patrol's Missouri Traffic Safety Compendium, built from the crash reports filed into the state's crash records system, MOCARS. In 2023, the latest year the Patrol has published, law enforcement reported 7,945 crashes in St. Charles County. 1,606 of them were personal injury crashes, meaning at least one person was hurt, and 22 were fatal crashes. The other 6,317 damaged property and injured no one the report recorded.

What these numbers are

They are counts of reported crashes. A crash enters the compendium when an officer files a report, and the Patrol sorts each report by where it happened and by its worst outcome. One death makes it a fatal crash. One injury makes it a personal injury crash, no matter how many cars were involved or how many people walked away. Table 1.13 sorts every Missouri county by those classes. Table 17.01 sorts the same year's crashes by municipality, which is how the county's cities get their own lines in this ledger.

The definitions are the same in Wentzville, Warrenton and Troy. That is what makes the tables useful: a line for one county can sit beside a line for the next without anyone translating.

What they are not

They are not a count of everyone who was hurt. A fender bender nobody reported to police is not in them. A sore neck that shows up two days later does not move a crash from property damage only to personal injury once the report is written. The personal injury class also lumps every injury severity together, from pain reported at the scene to a disabling injury, so these tables cannot say how many serious injuries the county had.

They are not rates, either. This desk does not divide crashes by population or by miles driven, because it would need a second cited source to do that honestly. A city with more crashes is a city where more crashes were reported, often because more traffic passes through it. It is not a verdict on the people who live there.

The tables in this ledger

What they mean if you were in one of these crashes

If your crash is one of the 6,317 property damage only lines, the report was written at the roadside, before anyone knew how your neck would feel on the second morning. That is common, and it is not a mark against you. Soft-tissue pain posts late, which is the subject of Feeling fine is an entry too. A crash report records what was known at the scene. An exam records what is true this week.

If yours is one of the 1,606 personal injury crashes, the same advice holds with more force: get examined within the week, bring the report number if you have one, and say it was a crash when you call.

How the numbers were entered

The Patrol publishes each compendium table as a web page. This desk pulled table 1.13 for 2019 through 2023 and table 17.01 for 2023 on September 13, 2026, and every figure in this section is generated from those pulls rather than typed by hand. The 2024 county table returned no rows when it was checked, so 2023 is the newest year here. When the Patrol publishes 2024, the ledger gains a line.

This entry is educational and is not medical advice or a diagnosis. It is not legal advice. The crash figures are counts reported to the Missouri State Highway Patrol and say nothing about any clinic, doctor, or office.
