I don’t see how a car can be convicted of committing a traffic infraction. Only a person can be responsible for that. And only a person can get the ticket, not the car. It seems to me for a conviction to be valid, there must be a photo of who is driving the vehicle, and they must be clearly identifiable in the photo.
On question: If the judge says “Ok, so you claim you were not driving the car. Then who was?”
Would you be required to answer who it was, if you actually knew? What if it was your spouse? Isn’t there a court policy that you are not required to testify against your spouse? And if you said “I don’t know”, that seems like it makes you an irresponsible car owner sinc eyou don’t know who is driving your car. But is that enough of an offense – if you say ‘I don’t know’ – to give you the ticket?" I expect there isn’t a clear answer to all of this. Legal-wise I mean. Here in Calif I don’t think you’d be required to answer even if you knew who was driving your car at the time the photo was taken. But other states are probably different.
