Is a trucking company using your phone for scale bypass?

no...you don't. In order for a cell phone system to work it tracks you tower to tower. That data is stored for a period of time on the cell company's database...the only way to eliminate it from tracking you is to pull the battery, then what good is a cell phone? If involved in any kind of incident, regardless of fault, the ambulance chasers subpoena your cell records and can see your movements, within a certain grid.
