About this data

Where the list comes from and what it does and does not say
144in the directory
144in the state register
15cities
3rdby size in this category

The largest concentration is in St. Charles: 42 of 144 (29%). Other cities covered include St. Peters (31), O'Fallon (29), Wentzville (16), St Charles (7), Saint Charles (4), and 9 more.

These 144 entries come from a register that publishes no license dates at all. For those, the only thing that can honestly be said is that the facility appeared in the state register when it was last refreshed, on September 23, 2026. No issue, renewal or expiry date is shown for them, and none is guessed.

The license classes represented here are Safety and Emissions Inspections (132), Safety Inspections (12). The class is the source's own wording, not a label applied here.

132 of the 144 (92%) hold more than one class of license. Each is one entry here, with every class it holds shown in its record detail. Across this page the classes held include safety (144), emissions (132).

All 144 publish a phone number. Phone numbers are normalized to one format here; the registers publish them several different ways.

The map positions were derived from the published street address through the US Census Bureau geocoder. No distance claim is made anywhere in this text; the "nearest to me" list computes straight-line distances in your own browser from your own location.

St. Charles County ranks 3rd of the 61 counties covered in this category, holding 5% of the listings, ahead of 58 others.

For a wider choice, the largest counties in this category are St. Louis County (452), Jackson County (249), Greene County (138), Clay County (90). They are ordered by how many entries each holds, not by how close they are.

Every record on this page comes from Motor vehicle inspection station directory, published by Missouri State Highway Patrol on mshp.dps.missouri.gov as dataset HP81Web. Each card carries the date the record was last re-checked.

What the rules require

St. Charles County: questions

Which cities in St. Charles County have stations?
By count: St. Charles (42), St. Peters (31), O'Fallon (29), Wentzville (16), St Charles (7), Saint Charles (4), Saint Peters (4), St Peters (3), Lake St. Louis (2), Cottlleville (1), plus 5 more. Addresses, license class and, where the register publishes them, license dates are in the list above.
Are these stations currently licensed?
The state register these records come from publishes no license dates, so the honest answer is narrower than it looks: each of these 144 facilities appeared in the register when it was last refreshed, on September 23, 2026. No expiry date is shown because none is published, and none is guessed. Confirm the current position with the facility or the issuing authority before relying on it.
Why does one address hold several licenses?
Because a row in the state register is a license, not a business. 132 of the 144 entries on this page hold more than one class at the same address, typically an inspection license alongside a repair or dealer license. They are merged into a single entry here, keyed on the facility rather than on the license, so one shop is one listing and its other classes appear on its own page.
Why do the cards not show star ratings?
No public rating has been matched to any of these 144 records, so no stars are shown. The license record is the stronger signal in any case: where the register publishes them, the issue date, last renewal, expiry and the state license number all come from the issuing authority, which is not true of a star average.

Something wrong on this page?

These records come from state registers and the registers are not perfect. If a listing is closed, has moved, or the license details do not match what the state told you, say so and it gets checked against the source.
