Passing up a weight station by mistake

December 2017, I passed up one of those old school non prepass weight stations on some two lane highway. This was in the north pole way up in Washington in the dead of the winter. This weight station looked bare. I thought it was closed or a non op. There was a brown sign that said "all commercial vehicles must enter the weight station". All I saw was a slab of cement with no one there. Of course as I passed up the small entrance, I finally noticed 4 sheriff cars parked way off to the side. I panicked and realized after the fact, that it was probably open! Once I saw the 3 semi trucks behind me pass the weight station as well, I thought "whew, I'm cool!" Well, 2 miles up the road, a sheriff came up on me with lights flashing, and pulled me over as well as the other 3 trucks. Took our licenses and made all 4 of us turn around to go over the scales and meet him in the office. $185 fine for each of us. I was so scared that it would give me points and go on my MVR. I see several fellow truckers asking the consequences of passing up a weight station. No one that I found seemed sure of the answer. Thought I'd share my results with you guys....5 months down the road, I went to get my H6 printout, and the offense was not on my record! Still to this day nearly a year later, it still is not on my DMV record! I did pay the fine immediately (which automatically means I plead guilty). I was a rookie OTR driver that made an innocent mistake. Now, I do not know if it effected my CSA score. I am still trying to figure out how to get access to my personal CSA score. I can get access to my employer's score by going to: www.https://csa.fmcsa.dot.gov/ Not sure if I got points for that even though my DMV record is clean. Not really sure how it all works yet. Hopefully I have no points if it never showed up on my driving record? Maybe this will relieve some of you who have made the same mistake. Then again, I don't know if weight station violation laws vary with each state. This incident happened in Washington. I have a California license.
