We get 30 days in California.Could be different laws in NJ. I did buy one new car when living in NJ in 2012 but I can't remember if they required me to actually list the new car on my insurance. I think in CA we get a 14 day grace period when buying a new (or used) car to add it to our current insurance. It may be different if you don't currently have auto insurance.
