How to fight a over weight ticket in CA ?

I am a licensed scale master for OR,WA,CA and ID. I have testified as an expert witness in court more times than I can remember.
From what you are describing, I think your chances of winning are about the same as winning the lottery without buying a ticket.
Scales that weigh subtractively (one axle at a time as you pull on) are notoriously inaccurate. A platform scale reads the weight distribution from each load cell underneath. Commonly, a 70' scale will have as many as 16 load cells, but as a single platform, more likely 8.
When you pull onto the scale at one end, you disproportionately stress the transducers and they read inaccurately.
Suffice it to say, a platform scale that you pull onto one axle at a time is only an APPROXIMATE weight.
If in doubt, go to to a nearby certified scale.
Most often, yard scales are not maintained and are not accurate. They often have not been recalibrated in YEARS!
A highway scale is calibrated at least once per year by law, but usually every quarter.
Sorry for the ticket. It will likely not end up on your CSA score.

 

If you show up to court, the bail amount usually gets reduce.

 

I look at scales as if we're playing Russian roulette. You hope the red light doesn't go off on you.

 

bubbles on a pittman arm is a lie that was used by the guy in the cali inspection lane to create revenue.There was no bubles due to there not being any lubricate there.Mechanics laugh when I tell them that I had to pay a guy who told me I was the 3rd truck in a hr with the same excuse,75 to take it off and wipe the dust off and put it back on.25 for ticket and more points on my csa

 

Well, I'm still not sure what it is supposed to be, but it just sounds bogus from the beginning. I'd definitely make sure the carrier fies a Data-Q challenge on that one.
