Brett, in CA the weight limit to keep an eye on at the scale head is 12,500 lbs for steers. If it's over, or close, I would stop the vehicle, check tire weight rating and re-weigh. It's not that common though because the scale alarm will only sound if it's over the tandem axle weight, so you would have to be constantly watching the scale weight as trucks roll by to catch a steer axle violation. However, under no circumstances would a vehicle be allowed to leave without first repairing any out-of-service violations. Being over the tire weight rating would meet the out-of-service criteria, regardless of any State regulation allowing it. I doubt they are allowing it. the 20,000 lb limit might be the total amount allowed on the steers if the tires are rated for it. A permit might be needed for anything exceeding that but the tires would always have to be rated to withstand the weight.
Tandem:
Tandem Axles
A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".
OWI:
Operating While Intoxicated
Out-of-Service:
When a violation by either a driver or company is confirmed, an out-of-service order removes either the driver or the vehicle from the roadway until the violation is corrected.
