Is it necessary to buy Rental Car Insurance even though i have my car insurance policy with me?

you don't need rental car insurance. you can take it, but for the most part, its just another way for the car rental firm to make more money. if you don't take the rental insurance and you do have an accident, the claim will be filed your car's insurance. if you are driving someone else's car and have an accident, it may not be covered since you are not an insured driver under that vehicle

yes by all means buy the insurance... they can sue you.. that insurance covers you for collision and libality... the extra price is worth it .. if you damage that car or someone lets say scratches it or puts a dent in the door you are liable.... when you rented the car with all that paper work you AGREED TO PAY FOR DAMAGES.. ok buy it..

Your policy only covers your vehicle and the the drivers of said vehicle. Other specified drivers can be named on your policy (like a spouse, parent, room mate etc..). The insurance does not carry over to other vehicles unless you include another vehicle on your policy (second car, child's car). You will pay for coverage on each vehicle that you have designated to the policy. If you are looking to rent a car for travel purposes, the lease will include a charge for for the insurance coverage of the vehicle that you're renting. Companies like Hertz, have deals with insurance companies to pay a flat rate for their rental cars. The amount of coverage that you will pay depends on the amount of travel or time of lease. Again, this surcharge will be included in your rental fee. If you drive someone else' car and have an accident, the insurance of the owner or policy holder of that vehicle will have to cover the damage. Again be careful, because while a few states offer policies in which any driver of a vehicle is coverered, most states require you to list the names of drivers on your policy. If a listed person has a lot of violations or is a high-risk driver, having them on your policy will cost you more. * It is true that in states that do not require auto insurance, you are free to opt out of the insurance offered by the leasing company; however, if anything happens to the vehicle, you are financially liable. If you're spending the money to lease a vehicle, then the extra $10-20 daily coverage is certainly worth the expense and will save you the hassle of taking out year long rental coverage with your own insurance co. After all, how many times throughtout the year do you find yourself renting a vehicle?

Ok. You have asked 2 different coverage questions here. Let me answer the first one. No you do not need to purchase the car rentals insurance. They will tell you that you need there rider insurance as your insurance company will not pay for the cars rental while the car is being fixed. That is bunk. You have a deductable regardless if you are the guilty party. If you are hit by someone else then there insurance company pays the rental fee loss. Now for question number 2 if you are driving another person car you will need to look up on your auto insurance policy to see if you are cover or ask the agent. (please see your coverage for all answers above)
