Collision Damage Waiver (CDW) provides protection for your rental against damages. CDW is offered at the time of rental for an additional daily charge. If you accept CDW, Scott's will waive or reduce your responsibility for loss of, or damage to, the rental vehicle up to $350. CDW is not insurance, it is optional coverage and not required. The protection provided by CDW may duplicate your existing coverage, therefore you should examine your automobile insurance policies or other sources of coverage to determine whether they duplicate the protection provided by CDW. Proof of insurance will be required at the time of rental.
