(3)
(A) The following is an example, for purposes of illustration and not limitation, of a notice fulfilling the requirements of paragraph (1) for a rental company that imposes liability on the renter for collision damage to the full value of the vehicle:
“NOTICE ABOUT YOUR FINANCIAL RESPONSIBILITY AND OPTIONAL DAMAGE WAIVER
You are responsible for all collision damage to the rented vehicle even if someone else caused it or the cause is unknown. You are responsible for the cost of repair up to the value of the vehicle, and towing, storage, and impound fees.
Your own insurance, or the issuer of the credit card you use to pay for the vehicle rental transaction, may cover all or part of your financial responsibility for the rented vehicle. You should check with your insurance company, or credit card issuer, to find out about your coverage and the amount of the deductible, if any, for which you may be liable.
Further, if you use a credit card that provides coverage for your potential liability, you should check with the issuer to determine if you must first exhaust the coverage limits of your own insurance before the credit card coverage applies.
The rental company will not hold you responsible if you buy a damage waiver. But a damage waiver will not protect you if (list exceptions).”
(B) When the notice in subparagraph (A) is printed in the rental contract or holder in which the contract is placed, the following shall be printed immediately following the notice:
“The cost of an optional damage waiver is $____ for every (day or week).”
(C) When the notice in subparagraph (A) appears on a sign, the following shall appear immediately adjacent to the notice:
“The cost of an optional damage waiver is $____ to $____ for every (day or week), depending upon the vehicle rented.”
(d) Notwithstanding any other law, a rental company may sell a damage waiver for each full or partial 24-hour rental day for the damage waiver, subject to the following rate limitations:
