There is a presumption that if you are the owner, you are the driver with camera photos. Nevertheless, you may be able to fight it. Seek an experienced attorney's aid. Many attorneys, such as myself, offer free 30 minute consultations.
The above is general information only and is not legal advice. The information provided does not form an attorney-client relationship, and should not be relied upon to take or refrain from taking any action. I am not your attorney until we sign a retainer agreement.
Unfortunately, there is a 'presumption' that you were driving, as owner of the vehicle. Do you know who was driving the vehicle? Can you prove 'who'? Did they drive it with or without consent? Do you let this person drive your vehicle regularly?
Per N.J.S.A. 39:4-8.15(b),you generally need to prove whoever was driving the vehicle drove the vehicle without express or implied consent. This requires proof, which I suggest you contact a local municipal attorney to ensure your proof is admissible at trial.
If you cannot prove it at time of court effectively, you will have to pay the fine. Keep in mind, there are no points assessed against your license, so there is no impact on your insurance.
If you can prove whoever was driving the vehicle, you can pursue this individual in small claims court for the fee.
