These additive amounts must be clearly shown as a flat dollar rate or as a percentage rate in the insurers' rate manual and may vary by coverage, liability limits, age and price of car, physical damage deductible, etc. The additive amount must be reasonable, not excessive, or unfairly discriminatory, however, as long as the program meets these criteria, an additive amount is not required to be assessed for every Chargeable Accident or Moving Violation.
