Untrue. What you probably heard is that if the officer didn't write down what happened and you went to argue, you might win since it'll be your word against the officer's, who didn't write down his word.
When I was young and dumb, I got a ticket for reckless driving. I went to argue it since I didn't think it was reckless, I was just making a quick left and my tires spun. Regardless, when I went to go argue it, the referee just said that I won and that the ticket will be dismissed. I didn't even get a chance to argue, I was just declared the winner cause the officer didn't write down what had happened in his eyes. So since it was my word against his absent word, I was innocent until proven guilty.
It really doesn't matter what the misspell, as long as they got the driver's license # right, you're stuck with it. No referee/judge in the world would let her off for a misspelling on the street name and the wrong year on the truck.
