What New Jersey rules say
- You may get your inspection up to two months before the date on your windshield sticker. (source: New Jersey Motor Vehicle Commission)
- Bring a valid driver license, the vehicle registration and a New Jersey insurance ID card, and the driver does not need to be the owner. (source: New Jersey Motor Vehicle Commission)
- Besides state inspection lanes, you can use a private inspection facility. (source: New Jersey Motor Vehicle Commission)
- Fully electric vehicles and motorcycles are exempt from inspection. (source: New Jersey Motor Vehicle Commission)
- Before filing a new car Lemon Law claim, you must send the maker, not the dealer, a last chance letter by certified mail, return receipt requested. (source: New Jersey Division of Consumer Affairs)
- That letter can go out after two failed repairs of the same defect, after 20 total days out of service, or after one attempt for a serious safety defect. (source: New Jersey Division of Consumer Affairs)
- The maker then has 10 days from the date on the return receipt to repair the car. (source: New Jersey Division of Consumer Affairs)
- Licensed used car dealers must give a warranty based on mileage, from 90 days or 3,000 miles for cars with 24,000 miles or less down to 30 days or 1,000 miles for cars with 60,000 to 100,000 miles. (source: New Jersey Division of Consumer Affairs)
- The used car law does not cover cars sold for less than $3,000, more than seven model years old, declared a total loss, or with more than 100,000 miles. (source: New Jersey Division of Consumer Affairs)
- A used car buyer may get a refund if the dealer fails to fix the same material defect after at least three attempts, or the car is out of service 20 cumulative days, with a $50 deductible per repair. (source: New Jersey Division of Consumer Affairs)
- Consumer Affairs advises getting a written estimate, and says any change to it must be approved by you, orally or in writing, before the work is done. (source: New Jersey Division of Consumer Affairs)
