Comment ALPR error happened to me (Score 3, Interesting) 67
I was pulled over by a town that uses ALPR (not Flock) on their cruisers. I was returning home after purchasing a new car, and MA allows using the plates off the old vehicle for 2 days, so I had some explaining to do. Luckily, I had all the appropriate paperwork, so not an issue (I'm also an older white male), and after checking my paperwork, they let me go.
Here's the weird part: the cop said the plate was supposed to be on a white van. I have never owned a white van. After thinking all of this over, I realised their plate reader didn't distinguish between regular plates and {TAXI, HEARSE, COMMERCIAL,...} plates, which have an additional line of text at the bottom of the plate.
Additionally, the same sort of thing caught my daughter up. This time it was EZPass. If you don't have a transponder, they use ALPR to figure out who owns the vehicle and bill you that way. She had been getting intermittent bill-by-plate entries in her statement (not unusual if the transponder doesn't read or has an old battery), but we didn't think anything of it. Until she tried to get a new transpoder and they told her she couldn't get one because she hadn't cleared her bill. Turns out, she had been paying for a white van with a COMMERCIAL plate, who had the same digits on their plate, and no transponder.
Same van? Who knows. But I have enough experience to know that those plate readers are not perfect, and the company behind them is less concerned with accuracy than making as much money as possible. What a surprise.
