§ 12728 Vehicle Weighing Certification Rules

Key Takeaways

  • •You can't weigh a truck or group of trucks if part of it is hanging off the scale. Everything must be on the scale.
  • •If the trucks are too long to fit on the scale together, you have to separate them and weigh each one by itself. Then you can add the weights together for the total.
  • •This rule doesn’t apply to weighing cotton trailers without brakes, or special weighing systems that follow other rules, or train cars carrying grain if everyone agrees in writing.

Example

A big truck with a trailer is at a weigh station.

If the truck and trailer are too long to fit on the scale together, the driver must unhook the trailer and weigh the truck first, then the trailer. The weights are added together to get the total weight for the paperwork.

(2) Multiple draft or in-motion weighing operations that comply with the regulations adopted pursuant to Section 12107.
