You can get your car inspected in New Hampshire up to three months (90 days) before your current inspection sticker expires. This early window is designed to offer flexibility and avoid the end-of-the-month rush. The expiration month is printed on your sticker, and the new inspection will be valid for one year from the expiration date of your previous sticker, not from the date you get the early inspection.
What to Bring and Expect Before heading to an inspection station, which are typically licensed auto repair garages or dealerships, make sure you have your vehicle registration and proof of . The inspector will check a range of safety and, for certain model years, emissions equipment. Common reasons for failure include:
It's a good idea to do a quick pre-check of these items yourself. If your car fails, you'll have 60 days to get the necessary repairs and return to the same station for a re-inspection without paying another full fee. Avoid waiting until the last week of your expiration month, as stations can get extremely busy.

My sticker says it expires in October, so I can actually go get it done in July, August, or September. I always aim for August. That way, I completely miss the crazy lines in October. I just drop it off at my local guy one morning, and it’s done. Beats sweating it out at the last minute.

The official rule allows an inspection up to 90 days prior to the expiration date on your current sticker. This is a proactive measure by the state to distribute workload for inspection stations throughout the quarter. ahead ensures your vehicle's compliance is uninterrupted and helps you avoid potential fines for an expired inspection, which can be over $100.

Check the month on the sticker on your windshield. Let's say it says "10" for October. You can get the new inspection any time in October, but you can also do it as early as August 1st. The new sticker will still be good through the following October. I learned this the hard way after getting a ticket once for an expired sticker. Now I set a calendar reminder for two months early.

You've got a solid three-month heads-up. The key is the expiration month printed on your sticker, not the exact day. If it expires in December, your 90-day early window opens October 1st. The benefit is that the new inspection’s validity gets added to the end of your current cycle, so you don't lose any time. I’d recommend calling your preferred station ahead of time to confirm their hours and if they take -ins, as some get booked up.
