You can nominate someone else if you have received a fine or overdue fine notice, but:
You weren’t driving the vehicle at the time of the offence
You sold the vehicle before the date of the offence
You are required by law to name the person responsible for the offence if demerit points are applied. Nominating the person responsible means the fine and loss of demerit points will be assigned to them, not you.
For offences such as littering from a vehicle, you should name the person responsible, even if you were the driver at the time.
For camera detected seatbelt offences, the driver must be nominated for both the driver and passenger fines. The driver is responsible for ensuring that any passenger in the vehicle is wearing a seatbelt. You can find more information on camera detected seatbelt offences on the Transport for NSW website.
