A motor vehicle monitoring method for determining driver negligence is carried out by a company in order to determine a final assessment for the vehicle. The method for determining driver negligence enables the company to calculate an average revolutions per initial odometer value and an average revolutions per secondary odometer value, where the average revolutions per secondary odometer value is a direct indication about operating state of the vehicle or an action of an end user during a designated time period. Then the company is able to adjust the contact agreement for the designated time period upon the final assessment, wherein the responsible party that violates the contact agreement is only liable for the respective damages. The method for determining driver negligence also validates the odometer and speedometer values from illegal tampering.
