The Missouri requirement: what state must readiness monitors be in? Missouri is very clear that readiness matters: a vehicle can fail if readiness monitors are not set to “Completed.” However, Missouri’s actual rule allows a small number of unset non-continuous monitors (because some vehicles—especially older OBD-II vehicles—can be stubborn about setting every single monitor quickly). The controlling Missouri rule provides: 1996–2000 model year gasoline vehicles may pass the readiness portion if they have no more than two (2) unset non-continuous readiness monitors. 2001 and newer model year gasoline vehicles may pass the readiness portion if they have no more than one (1) unset non-continuous readiness monitor. That’s the practical standard drivers run into: “2001+ = only one ‘Not Ready’ monitor allowed” (and 1996–2000 = two allowed), assuming the rest of the OBD emissions criteria are met. A special “gotcha” people miss Missouri’s rule also calls out catalyst-related trouble codes: if you fail with a catalyst converter DTC (P0420–P0439) present, the catalyst monitor status becomes particularly important for the retest readiness portion. In plain English: if the car has catalyst efficiency codes, you’re not just battling readiness—you’re battling an emissions fault that the state expects to see resolved and properly rechecked. What happens if you fail only because monitors aren’t ready? GVIP acknowledges that some motorists fail only due to “too many Not Completed monitors.” In that case, Missouri provides a Readiness Monitor 30-day extension concept: if you fail only for monitors, you can legally drive the vehicle for up to 30 days beyond registration expiration to reset monitors—keeping your test report as proof. This is basically the state recognizing a reality: you sometimes need real-world driving time—under the right conditions—to complete monitors. How fast can the inspection be when the car is ready? When a vehicle is already “ready” (MIL off for emissions-related faults, monitors set within the allowed limit), the actual inspection process can be quick because it’s largely: verify vehicle info, 2) connect to OBD, 3) confirm results, 4) print/report. GVIP itself describes the OBD process as attaching a cable to the vehicle’s computer to determine whether the emissions system is working and whether readiness is complete. So, in the real world, the bottleneck is often wait time and paperwork, not the data read itself. Where Sant Automotive fits in (speed + customer sentiment) Sant Automotive (8720 Watson Rd, St. Louis, MO 63119) is one of the well-known local shops that performs safety/emissions inspections. On the question of speed: it’s best to treat “fastest in Missouri” as a marketing claim, because Missouri doesn’t publish an official statewide speed ranking for inspection stations. What is verifiable is that Sant Automotive has public feedback emphasizing quick inspections. For example, Carfax reviews include customers explicitly saying “Very fast service on a recent emissions inspection.” And more broadly, Sant’s own site highlights customer testimonials and a service model oriented around efficient scheduling and a strong customer experience. So, the fair way to say it is: The 10-minute emissions inspection is plausible when the vehicle is already ready and there’s no line. Sant Automotive is known locally for quick emissions visits, and customers frequently praise the speed and service in reviews. Bottom line: what to do before you show up for a Missouri emissions inspection If you want your Missouri emissions inspection to be fast (whether at Sant Automotive or anywhere else), show up with the vehicle in the right state: No active Check Engine Light for emissions faults Readiness monitors set within Missouri’s allowed limit 1996–2000 gasoline: ≤ 2 unset non-continuous monitors 2001+ gasoline: ≤ 1 unset non-continuous monitor Avoid getting codes cleared right before inspection unless you’re prepared to complete a drive cycle afterward If you fail only for monitors, use the state’s guidance (including the 30-day extension concept) and drive the vehicle through mixed city/highway conditions to set them. If you tell me your vehicle year/make/model and whether you recently disconnected the battery or cleared codes, I can give you the most likely monitors that will be stubborn (EVAP is a common one) and a practical “drive cycle” strategy to get ready quickly.
