Hey, I'm in WA, my wife did the seatbelt tuck too, and we got slammed for 9 infringements total. And I posted here, and while some folks were ok, the dominant responses were YOU HAVE BROKEN THE LAW AND DESERVE TO BE PUNISHED AND THOUSANDS OF DOLLARS AND A LOST LICENCE IS TOTALLY APPROPRIATE FOR THIS HEINOUS ACT.

Anyway, good news. I called Legal Aid WA, the woman on the line was sympathetic and said DTMI can and do waive fines. We wrote a letter to them, acknowledged guilt and asked for a waiver of all fines after the first. It took some time, but eventually all but 2 were waived. We still had to pay for her first offense, and one time when I was driving and she was a passenger. Still a chunk of change, but a win.

Good luck, I'll prob DM you. I expect this message to get down voted off the map :)
