Intoxilyzer 9000 vs Older Models: What Changed for Operators

What actually changed between the Intoxilyzer 9000 and earlier CMI models?
The Intoxilyzer 9000 replaces the older models' keypad and small LCD readout with a color touchscreen that walks the operator through each step of the test sequence, and it swaps the 5000/8000's dot-matrix strip printer for a full-page laser printer that produces a cleaner, more complete evidence ticket. It also adds a built-in driver's license card reader that pulls subject information automatically instead of requiring hand entry, and it displays a live breath flow and pressure curve during the sample so the operator can see in real time whether the subject is blowing a valid sample. None of this changes what 49 CFR Part 40 requires of the test itself. It changes how a Breath Alcohol Technician executes the sequence, reads the screen, and confirms a valid result before it prints.
Does the touchscreen change how a BAT runs the test sequence?
Yes, and it is the change that causes the most operator confusion during a fleet upgrade. Older Intoxilyzer models used physical buttons tied to fixed menu positions, so a trained operator could run a sequence from memory without reading every prompt closely. The 9000's touchscreen reorders and relabels those same steps as on-screen buttons, and a BAT who is used to counting button presses instead of reading the screen can tap the wrong prompt, especially under the pressure of a post-accident or reasonable suspicion test. The fix isn't complicated: treat the 9000 as a new instrument for training purposes, not a software update to the 8000, and have every operator run several supervised practice sequences on the actual touchscreen before using it on a real subject.
Is the Intoxilyzer 9000 approved for DOT alcohol testing?
The Intoxilyzer 9000 appears on the National Highway Traffic Safety Administration's Conforming Products List of evidential breath measurement devices, which is the list 49 CFR Part 40 requires an instrument to be on before it can be used for a DOT confirmation test1. Employers switching from an older Intoxilyzer to the 9000 don't need a new DOT approval process for the instrument itself, but they do need to update their written testing program, notify their consortium/third-party administrator (C/TPA) if one manages the program, and confirm the specific unit's own calibration and inspection records carry over correctly to the new serial number. A CPL listing covers the instrument model; it doesn't substitute for that specific unit's individual calibration history, which is why routine Intoxilyzer calibration and accuracy checks matter as much as the CPL listing itself.
| Feature | Intoxilyzer 5000/8000 | Intoxilyzer 9000 |
|---|---|---|
| Input method | Fixed keypad, dedicated buttons | Color touchscreen, on-screen prompts |
| Printer | Dot-matrix strip printer | Full-page laser printer |
| Subject ID entry | Manual keypad entry | Driver's license card reader plus manual entry |
| Breath sample feedback | Numeric readout only | Live graphic flow, pressure, and BAC curve |
| Observation period support | Manual timing by operator | On-screen countdown timer |
What should an employer check before switching instruments?
Before a program moves to a new instrument model, confirm three things in this order: the specific unit is on the current NHTSA CPL without an asterisk restricting it to screening-only use, every BAT who will operate it has completed instrument-specific training on that model (not just a general Part 40 refresher), and the calibration and maintenance schedule for the new units is set up before the first live test, not after. A program that swaps instruments without re-training operators on the new screen sequence is the most common way a confirmation test gets challenged after the fact, because a mis-tapped prompt or a skipped screen can void the sequence even when the underlying reading was accurate.
How Foster handles Intoxilyzer transitions
When a customer moves from an older Intoxilyzer to a 9000, Foster's field techs walk the site's BATs through the new touchscreen sequence during the same visit as the instrument's initial calibration, rather than treating training and calibration as two separate appointments. That visit also updates the customer's written testing program reference to the new model and serial number, confirms the driver's license card reader is reading correctly for the states the workforce is licensed in, and leaves the site with a laser-printer ticket sample on file so the BAT knows what a complete, valid printout looks like before they run their first real test on the new unit. Foster is an authorized distributor and service provider for CMI Intoxilyzer instruments, with technicians trained directly by CMI on the current model line.
Foster also handles the training side directly through its DOT BAT training program and keeps instrument fleets current through scheduled calibration service. Programs weighing a switch can start with a quote that covers both the instrument transition and the operator retraining in one visit.
Frequently Asked Questions
Can a BAT trained on the Intoxilyzer 8000 operate a 9000 without additional training?
Not under a defensible program. Part 40 requires a BAT to be trained on the specific device they use, and the 9000's touchscreen workflow differs enough from the 8000's keypad sequence that operating it without instrument-specific training creates a real risk of a voided or challenged test.
Does upgrading to the Intoxilyzer 9000 require a new calibration schedule?
Yes, in the sense that the new unit starts its own calibration and maintenance history from the date it enters service, even if the program's overall calibration interval and vendor stay the same as the retired unit.
Will the Intoxilyzer 9000's card reader work with an out-of-state driver's license?
It reads most standard US driver's license barcodes, but formats vary by state and some older or non-standard licenses may need manual entry. Operators should be trained to verify the auto-filled subject information against the physical license rather than assuming the card reader is always correct.
Is the Intoxilyzer 9000 the only current CMI model approved for DOT testing?
No. Multiple CMI Intoxilyzer models remain on the current NHTSA Conforming Products List. Employers should confirm the specific model and unit they operate is listed without a screening-only restriction before relying on it for confirmation testing.
