If payment was not completed on the due date of your monthly installment, your insurance policy will be placed on pending cancellation for non-payment of premium and the DMV will be notified.
INSHUR will generate a reinstatement invoice that will include your monthly installment + $50 reinstatement fee.
You will have at least 20 days to pay the reinstatement invoice before your policy is effectively canceled.
To prevent missed payments make sure you have an up-to-date default payment method entered and you are familiar with your payment schedule.
