Does the driver of the car have to be physically identified for a red light ticket to be valid?

Although I do not practice in your state, red light traffic cameras are typically civil, not criminal, infractions. It's more like a parking ticket than a speeding ticket. The owner is presumed to be responsible but the owner can typically rebut that presumption with an affidavit pointing out who was driving.

If the equipment is not routinely calibrated and compared to standard, then you may be able to defeat the evidence.An attorney familiar with the policies and procedures of the court will know the likelihood of negotiating such a resolution given the circumstances of your case.

Check with a lawyer in your locale to discuss more of the details. You can bring valid evidence that the challenges the data upon which citation is issued. Your challenge must comply with the rules of evidence, so an attorney skilled in such matters can be of great assistance to you so that your rights are protected.

Good luck to you.

God bless.
