How long has it been since YOU were in driver's ed?

The other day, I was driving along, minding my own business and obeying all traffic laws and all of the sudden, the guy behind me honks at me. He honked because he wanted me to turn right on red. But it wasn't just any ol' red- it was the dreaded red arrow. (dun dun DUN) I was at the complicated intersection of Excelsior Blvd, Hwy 100 and some frontage road, and even though I was turning right, I didn't think that it was lawful to turn on a red arrow, no matter which way you are going. Otherwise they would have made it just a regular red light, right? right.
So I didn't go until the light turns green.

Mr. Asshat was so pissed off by such lawfulness that he then had to tailgate me all the way to the gas station. He actually followed me! And then got out of his SUV! And I was totally panicking! Baby Atilla was in the backseat, and I was closer to work than to home, and god had I remembered to charge my cell phone?!?

After memorizing his plate number, I got out of my car, with my phone in one hand and my keys between my fingers in the other hand, and tried to catch the eye of the gas station clerk to telepathically let them know they should call the cops now.
And then I said:
"Do you have some kind of a PROBLEM?!?"
He said, "NO!" and then got back in his SUV to swear to himself. I could see him in there with the hand waving and the flying spittle and everything.
He got back out and said, "You can turn right on red, you know."
I said, "Nope, not on a red ARROW."
He said, "There was no sign saying that you can't."
"Yes, but it was a red arrow, so you can't."
Asshat says, "Oh.My.God. How long has it BEEN since you were in driver's ed?" and I realize that he is pretty young. I'd guess 22-23 at the outside.
And I said, "I teach driver's ed, punk." (ok, no I didn't, but that would have been funny! And part of the reason to even have a blog is so that I can have a place to use all those witty comebacks I think of hours, days and weeks too late to use. *sigh* I actually said something lame and old sounding about being a licensed driver longer than he's been alive or something.)
Then he bought his $5 worth of gas with his allowance money and we parted ways.

And then, because of how I am, I had to go home and look up the traffic laws to see if I was right.
In many states, it's a little fuzzy, and in North Dakota you can turn on a red right arrow, (but it's not like people in ND use traffic signals at all anyway, they just think the lights are there for pretty.)
But not Minnesota by god. Minnesota statute 169.06, subdivision 5, part iii, clearly states:
"Vehicular traffic facing a steady red arrow signal, with the intention of making a movement indicated by the arrow,
must stop at a clearly marked stop line... and must remain standing until a permissive signal indication permitting the
movement indicated by the red arrow is displayed, except as follows: when an official sign has been erected permitting a
turn on a red arrow signal...or to turn left from a one-way street into a one-way street on which traffic moves to the left, after stopping, but must yield the right-of-way to pedestrians and other traffic lawfully proceeding as directed by the signal at that intersection."

Ok, that's not all that clear, and I even edited for relevance, but the point is, I was right, Asshat, I was right.
