The grade system of the Automobile insurance is to discount insurance to the person with few risks of causing the accident, and to surcharge insurance for the person with a high risk reasonable.
And, when driver's grade is contracted to another insurance company because it becomes a standard by which the driving risk is shown, the grade will be succeeded.
However, if the contract cannot begin within one week from the maturity date when the renewal of a contract or the insurance company is changed and it contracts newly, it becomes a new contract, and the grade becomes six grades, too.
Because the current accident-free will not be reflected in insurance for the person who has improved the grade, the procedure finishes ahead of time, and takes care not to down the grade.
When the accident has been caused oppositely, it doesn't return to six grades, and the history of the downed grade will remain as it is for 13 months.
