The judge in this case disagreed, because the red light infraction was not a simple civil fine but quasi-criminal, e.g. points on drivers license, possibly resulting in suspension, etc.
The structure of this whole thing is to avoid having to do an actual investigation. They could subpoena the car owner's phone records for instance. Instead they choose to hide behind bureaucracy and offer you an off ramp in the form of a lower payment to make it all go away.
Do you know you can be licensed to drive a vehicle without owning one, and similarly, own one without being licensed to drive it?
Why would the owner of the property be responsible for someone else's actions with that property?
But for the purposes of traffic tickets, yea, its ridiculous. It also has a lot of faults. I got a traffic ticket from a red light camera for a car I owned when I was stationed in California. The ticket came to me in Oregon 5 years AFTER I traded that vehicle in (I traded it in right before moving to Oregon) and the traffic cam ticket was from Texas, a state I've never driven a vehicle in. My only presence in Texas has been being in the airport in Dallas. The ticket was also for a year prior to when I received it. So I hadn't owned it in 4 years when it ran a red light in Texas.
The owner isn't responsible for the drivers actions, but they are required to name the driver. (Or declare the car stolen etc.)
(At least in much of Europe.)
As someone else said, this only works against self-incrimination? If you say it wasn't you then you need to testify or get prosecuted?
Second, you can still generally invoke the 5th amendment during testimony even if you already claimed someone else did it. You aren't under oath until said testimony, so it still protects against you having to choose between committing perjury or self-incrimination, and doing so cannot be used as evidence of either.
And you plead the 5th after going under oath. And you can't just plead the 5th to any question. If the prosection puts you under oath and asks you your name, you can't plead the 5th to that
5th amendment protections can include questions of identity, if the question of identity is relevant for incrimination. Like, if the government has a warrant for "Joe Smith", you're not required to testify whether that's you. It's usually a waste of time since could just prove it with the non-testimonial evidence that lead to your arrest, but the protection does exist.
Most camera tickets are either civil moving, or civil non-moving. Civil moving are against a person and civil non-moving are against the vehicle. Neither of which case does 5th amendment protect you from incriminating yourself, and neither of which does it require prove beyond a reasonable doubt.
