Generally, insurers don’t put a ceiling or restriction on the number of claims you can file with your car insurance policy in a policy period. You can file as many claims as you want if your vehicle suffers frequent damage due to accidents.
Having said that, please note that if you make too many claims in a policy period, your insurer can also add a clause in your policy while renewing it. Such a clause can restrict the number of claims you can file during a policy period.
