How does it report you?
“How does it report you?”
When you take the car in they put their code reader on it. The color sensor sets a code. Then, they check the dye pack to verify that code. Then, by law, they must call the appropriate office. You get fined $10,000 for using untaxed fuel.
You’d be fine if you never took your car to a dealer. But there are things that are dealer only and you really have no choice. (I don’t know what would happen if you took it to Joe Shadetree and he read the code. Presumably, he’d report you as the laws are usually broad and the code reader is likely to tell the user the penalty for non-reporting.)
