This practice should be ruled unconstitutional since it only applies to certain drivers and enforces a BAC level that is 75% lower than the legal limit. In effect, it creates a set of laws for one class of people that is different and more onerous than for another class of people. In my opinion it violates the equal protection clause of the constitution.

Their is a cost involved with installing the device, removing the device, servicing it and a monthly service fee that runs $75 to $125 a month. These fees, not surprisingly, are paid by the driver and not the state. Register your displeasure with the law by calling your representatives in Missouri and asking them to show you how this law will save lives or reform repeat offenders without providing them with any rehabilitation.
