If you are not at fault, you are entitled to payment from the at-fault party for a rental car similar to your own.
If fault is in dispute, check your own policy to see if you have rental coverage.
If you choose not to rent a car, you may be entitled to compensation for what is called “loss of use.” Essentially you receive a reasonable daily rate in lieu of the rental car.
At times, a car accident victim and an insurance company cannot agree on these rental terms (i.e. how long a rental car is needed, how much to pay, or how long payments should continue).
You then have the option of contacting the Consumer Affairs Unit which is a part of the Connecticut Insurance Department.
