Hold the pickle

There was a cop in an SUV conspicuously parked on the street outside the school this morning, pretty typical.

So I dropped her off and looped around the lot, and when I pulled back onto the street and slowly approached the SUV from behind, I noticed thin gold letters on the back left side that said CITRON. I was like, “Wait, what? Is that like a regular cop but with a twist of lemon?”

As I got closer, I realized it was just the word CAUTION but the letters had been partly pressure-washed off or something and that made it a little harder to read.
