‘What is a deductible for car insurance?’ is not a difficult question to answer. A car insurance deductible is a part of the insurance that the policy holder must pay in the event of an accident. It is the participation fee that you must pay, which is a portion of the total cost of the damage claim. For example, your car gets damaged and the total bill is $6,000. If you chose an insurance deductible of $500, then you will have to pay that $500, while the insurance assumes the other $5,500 for the repair. It is very important that you determine the optimum amount of car insurance deductible that you are willing to pay and talk to your insurance broker about the options they can give you.
