It should be noted that the insurance chosen on the car rental website is much cheaper than that provided by the car rental company, but if you need to compensate the car rental company for the accident, and then go to the car rental website to claim compensation, it will be troublesome, but the cost is much less, and there may be a limit. This time I rented a car on Priceline, the insurance cost was $10 a day, and the claim limit was $35,000. Generally speaking, that's enough. The premium paid at Nationals is about 20 Canadian dollars a day, or at least twice as expensive.
