You’re fine…you retested OK within a few minutes of the warning. Remember…your state has thousands of drivers using interlock devices… Thats produces 100,000 of thousands of “test results” that the interlock companies have to store and somehow email or make available to the motor vehicle division in each state. They dont have the manpower or staffing to review all those results. The interlock companies get the fat…they make money by the driver having to come in for a re-set or re-calibration if you record a violation. Warnings are just that…warnings..and no-one will give it a second look…or a first!
