Can you drive 12 hours or more and not leave the state?
Texas (yo, Alaska, does this apply to you to?)
Yes.
Also California.
Were 3 words recently dropped from the name of your state?
Yes=Rhode Island (formerly Rhode Island and Providence Plantations)
Did both Mork AND Mindy grow up in your state?
Yes: Michigan
Technically, you can drive more than 12 hours without leaving the state in every state.
Does your state have an iconic symbol that slid off the side of a mountain?
Yes: New Hampshire (The Old Man Of The Mountain/Great Stone Face)
I guess it’s “Live Free or Slide off the Mountain”? Has it made those state quarters more valuable?
Can you drive 12 hours or more and not leave the ZIP code?
Yes = Washington DC suburbs
(ok, ZIP code is an exaggeration. Area code, now…).
And I’ve got some counterexamples on the sate thing: Someone driving from Key West to Pensacola would likely take 12 hours (confirmed via Google Maps just now). Kootenai Falls, MT to Hammond, MT would also take 12 hours.
Can you dig for diamonds in this state?
Yes you can.
Arkansas.
(Murfreesboro, Ar. Crater of Diamonds State Park. And you can keep what your find. Really)
According to Google Maps, Mexico to Oregon on the 5 in Cali is just over 12 hours.
Sure. I guess they could ask “Can you drive in one direction for 12 hours and not leave the state?” I figure Alaska could change that to 24 hours since they could split into two states and make Texas the 3rd largest state.
Well you can still do that in any state, if you drive really slow. 
Do Saguaros grow here naturally?
Yes = Arizona.
Regardless of what the movies show, Saguaro cacti only grow in the Sonoran desert of Arizona and Mexico.
Did your state tourism board promote your state with a “Yes, Michigan” jingle?
Yes: Michigan
So, I guess this branding is not entirely accurate?:
Yep. I went to New Mexico for the Annular eclipse last fall, and I was looking at the T-shirts, and couldn’t help but point out all the inaccurate ones which had NM cities with Saguaros…
There are federal and state regulations for “roundabouts” in California. Stockton CA also has regulations for “traffic circles”, which are different. I assume other cities do, too.
If you’re a kid, and your parents might be nearby, it’s “hecka”.
Do you call sections of temporary concrete dividers “k-rail”? California (not generally known)
When the constant call to cut the state in half (north from south) comes up, does someone make that tired joke about the diet states? California (No.Cal and Low Cal)
Do you get a check from the state just for living there AND pay no state taxes?
Yes=Alaska
The stock response to the 12-hour claim is “Yeah, that sucks. I once had a car like that too.”
Makes me so glad I don’t live in Florida.
Can you pronounce Mackinac, Dowagiac, and Gratiot correctly? Michigan.
