This will not be an exciting story. I haven’t broken any major laws accidentally (or on purpose), but I did once leave my vehicle registration for too long, and I was driving on expired stickers. I didn’t get stopped by the cops, so no drama. I discovered the problem some two months after they expired, however, so I could have gotten stopped by the cops at any given time.

I realized I was waiting for a postcard reminding me that my registration was due, and I had never gotten one. This is not an excuse, according to the license bureau.
Fixing it was as simple as going to the license facility and standing in line, all the time hoping that a cop wouldn’t find my car parked out front with an expired sticker. They did not, but I had to pay a fine for waiting too long to get the sticker. I found out that someone had transcribed my license number wrong on a form and that was why I didn’t get a postcard.
This is definitely not one of my more exciting stories.
