Should I add CDW coverage?

When you rent a car in Guam, adding CDW (Collision Damage Waiver) is a good idea, just in case.

If the rental car is damaged in an accident, CDW limits your share of the repair bill (on repairs up to $50,000) to a $1,000 deductible. Guam's traffic rules may differ in places from what you're used to, and driving somewhere new carries some risk of a minor collision. With CDW, you can drive with peace of mind.

CDW applies only to collisions between vehicles where both have a driver. The next question explains when it doesn't apply.
