What is a Collision Damage Waiver, or CDW?
This is collision damage coverage for a rental vehicle. This is required if you do not carry any optional collision coverage on your own automobile policy. For a daily charge, this coverage is available from the rental company. You will not be reimbursed for this expense since it is coverage in excess of what your own policy provides. It is important to point out again that you do not need to purchase this additional insurance if your own policy has collision coverage and you are in a rental vehicle as a result of a claim.
