My inspection is up in September. Can I go early before that month ?

I believe 1 month in advance

I think that You are able to get the Inspection One Month in advance. But Make Sure Your Paperwork is Okay and Isn't Expired Before Or After that your Inspection is Scheduled. Thanks. Enjoy your BLESSED Day. Ⓜ️💯🙏🍀🐘👩‍👦💒🌅

I believe you can go up to 60 days in advance of the expiration

Yes

Absolutely

Yes. You can go early

Yes, the earlier the better.

You can have your car inspected up to two months early according to NJ inspection website.
