1. A method for recording discrete events of a haulage vehicle, the method including the steps of:

  • sensing two or more conditions of the vehicle having values that vary dynamically as the vehicle is in use, where one of the conditions is a weight of a load carried by the vehicle, comparing the values of at least one of the conditions to a reference value, applying one or more criteria to determine whether the comparison identifies a haulage event that is to be recorded, and, recording to a memory values of the conditions when the determination is that a haulage event has occurred.
