Does my travel insurance cover Car Rental excess? Rental insurance excess can be very high regarding, stone chips. Scratches and windscreen chips commonly occur on unsealed roads.
Take the time to walk around the car, boat or bike and take some pictures, not forgetting the cars windscreen, and avoid unsealed roads whenever possible. Dash cams are so cheap now, and are a handy travel insurance policy in themselves.
Hidden fees may be more difficult to determine, this is why you should look at reviews which may help you uncover any tricks or policy conditions, I like to use Twitter (see travel insurance reviews) which I find very useful to review almost anything.
