According to the New Jersey's Drivers Manual, driving a vehicle with an expired inspection sticker may result in fines of between $100 and $200, and/or imprisonment for up to 30 days. Additionally, MVC may revoke registration privileges.
We believe that the penalties for driving a properly registered and insured vehicle in NJ without the inspection sticker would have penalties such as the ones listed above for driving with an expired inspection sticker since both mean that your car has not been properly inspected in the time frame required by the state.
If you have been ticketed for driving without an inspections sticker in NJ then check with the court listed on your citation to find out what penalties you may be facing. Or you may also choose to contact the New Jersey Motor Vehicle Commission (MVC) directly to see if they can tell you what penalties are associated with this offense.
