Oh, yeah! Got pulled over a couple days ago for an expired registration. I don't know what it is about me, but every, single year, I forget to renew on time. My birthday was a couple weeks ago, and I knew I had to renew by April 1st, but my brain just cannot retain that information prior to expiration. Fortunately, the officer was really cool about it, saying he wasn't going to write me a citation, he just wanted to let me know he knew and nudge me to take care of it. It's done now.
Tangentially, Texas registration is on the front windshield; how do cops see it when they're behind you?? I don't know how it is in other states, but in Ohio, your registration is on your rear license plate, so it makes sense they can see an expired tag.
Anyway, I'm legal again. This time next year, expect a similar post.
