1) CDW (Collision Damage Waiver),
LDW (Loss Damage Waiver), PDW (Physical Damage Waiver).
Although technically not collision insurance, in return for a
daily fee, CDW or LDW waives the right for a rental car company
to recover money from the renter if the vehicle is damaged or
stolen. This does not cover damages made to someone else's car
during your rental (third party damages). Your personal or
business auto coverage normally covers this when you are renting
a car. Check first with your car insurance agent.
Some CDW's can even become void
in certain circumstances. This may happen if you drive in a
negligent manner or out of the state in which you rented the car
if geographical restrictions apply in your rental contract.
2) Personal liability
coverages such as LIS (Liability Insurance Supplement).
Besides LIS, an agency may offer supplemental or additional
liability coverage which pays over and above what your personal
or business insurance covers. If you do not already have
personal liability coverage you should purchase the rental
agency's.
3) PAI (Personal Accident
Insurance or Coverage). This provides a one-time payment for
you or a passenger in case of death or maiming from a car
accident. This is generally covered under your auto or health
policies.
4) PEC (Personal Effects
Coverage) or Personal Property Insurance. This pays if you
have something lost or stolen from your car. Opting for this
coverage is obviously something you have to decide for yourself
since your existing coverage probably doesn't include this
coverage.
Although many of these except PEC
may be covered with your existing personal car insurance policy,
its a good idea to check your insurance policies with your agent
first.
